Comments

Afua Jan 28 2026 8:19 pm This series had great potential but the excessive fight scenes where the ML takes an unrealistic amount of punches to his head were hard to watch and did not enhance the story. Gratuitous violence is unnecessary to make a drama believable

Kim Chiu Dec 21 2025 12:36 pm Weird how some people are complaining about the kdrama lol. I saw someone hating on the villain being an ordinary person. News flash: your bestie could be the one ruining your life. Main characters need not be perfect. Humans have flaws. If you've met an athlete, you'll know that most (if not all), are single minded and hyper focused on winning. For those complaining about the action scenes, go watching something else.

I love this drama. At first, I was complaining with how PGM was acting tough because his real personality kept on showing. But, as I see the effort he put in this drama, I have no right to complain. FL also did her work. Her action scenes were executed very well. The sabre guy frustrates me the most coz he kept on getting hurt lol.

This is a good police drama for athletes whom people forget if they don't become celebrities. Respect to all the athletes reading this.

Kdrama Stan Dec 07 2025 12:15 pm This drama started off great but after ep 7, it became boring. It should have been 8 eps long. 16 was just a stretch. Everything became so repetitive. The constant temper tantrums from the main lead were so annoying. Him constantly getting beat up and coming up with whatever motivational speech was just too annoying. The only well written character in this show was the villain. The lead couple had zero chemistry and they both had unlikable personalities. This show had so much potential. Drugmon should have been given more to her character. She started off strong but ended up being a weak character. I was so disappointed. She should at least have been a bad ass in a fight. Overall I'd give this show a 4/10 and that's me being generous. Idk what the writters were trying to come up with but it didn't work

Elyu Nov 29 2025 6:39 am Main character cops of this series are so dumb-stupid and always get outsmarted by the main villain.

Yeruchii Sep 03 2025 6:37 am I was so excited because we have another KSH dtama plus PBG is here. But episode 10 onwards was a struggle to finish. The heart of the plot got lost elsewhere and never came back. It started good but became a mess as it goes on. Usually fight scenes excites me but this one was just borderline ridiculous. It's.just fight after fight that the story just became a backdrop. The romance was also unfulfilling. It needs something more. I didn't even felt it. There are also a lot of parts unexplored. It took me a while to finish this because I go somewhere to refresh my brain before I continue. I only managed to finish this because I can't let a drama I watch go unfinished and because KSH is my fave.

Ban Aug 28 2025 7:06 pm At some point PBG taking head shots over and over again just gets boring and annoying. The show definitely has highlights but it’s really dragged down by repetitive and completely unrealistic action scenes.

Ardi Aug 28 2025 12:53 am This series has a good premise, where an athlete becomes a police officer. However, it’s quite disappointing that the villain is written as a perfect character he even disguises himself as an ordinary civil worker. Meanwhile, the main character is portrayed as reckless, has anger issues, and isn’t smart, even though he’s a boxing athlete and an Olympic gold medalist. His character feels completely at odds with his background.

Ddeonu Aug 24 2025 1:13 pm I just finished watching this drama. I found it exciting, entertaining, and spiced up with a romantic comedy. All the actors in this drama played their roles very well.

Especially our villain, Oh Jung Se. In real life, he's introverted and very shy. But he played his role very well. He didn't even repent until the end, haha.

But I was a bit annoyed by Dong Ju's character, who kept getting battered even though he eventually won.

A drama that never gets boring. 8.5/10

Mywoman_Yeaji Aug 23 2025 5:15 pm I watched this movie because of PBG and yep I definitely loved seeing him on my screen but gosh I hate how hotheaded his character was and how he kept getting punched.

Phewwww... If you want an emotional rollercoaster, can ignore plot holes and you have a love action. Then you should watch this.

It's a great movie but it could definitely be better. It's great if you're seeing it just once because it keeps you wondering what happens to the villain to the very end and wraps it up nicely.

I doubt it can be watched twice though you'll most likely not be able to ignore plot holes and the lack of character development.

Jamse Aug 16 2025 3:01 pm Has anyone kept track of how many times per episode the Dong Ju character gets punched in the head? I couldn’t keep up.

clara Aug 11 2025 10:47 am who is the actor that plays young leo in the flashback from episode 13?

Jiso Aug 06 2025 10:24 pm Please make season 2 or another movie/drama that park bogum and kim so-hyun are paired i like the movie

Osh Aug 04 2025 12:40 am Hate the ML character, he is very annoying, especially when he act cute and smile, don’t know why write a character like that in a non romance focused show. And I don’t think the olympic setting has anything to do with the rest of the plot, an ordinary police team like other show will still work for this storyline, badly written.

IlovePBG Aug 03 2025 7:39 am

SPOILER ALERT*

The only reason we watched this was because of PBG. I don’t understand what the writer and director were thinking. They keep letting the enemies win—an unlimited wave of them armed with knives, axes, and pipes. There’s even a scene where PBG was drugged, hit by a car, stabbed, and then became a fugitive—all in one day. They could have wrapped up the series in 12 episodes, but they dragged it out to 16, which made it feel unwatchable and unlikeable. I feel bad for PBG for taking on this project.

But still hats off to PBG for his great fighting skills - his boxing skills are really good and you can tell how much he prepared for this show.

Neil Jul 30 2025 2:47 pm This was a very hard show to watch for many reasons. The ML and FL had no chemistry at all. The ML is played as very hot-headed and reactionary which is a handicap to the investigations The group is fighting an international group of mafia with very few weapons. The mafia people are all carrying knives, guns, pipes or sticks in every fight scene. But the cops are incompetent by not arming themselves or calling for backup before going up against them time after time after time. The FL is the only one that has access to a gun that shoots paintballs or tiny sandbags, but keeps getting beat up because she keeps hitting people in the leg out missing. The writers and director should apologize to the actors who had to carry out this plot hole laden show.

Tililing Jul 30 2025 9:53 am I did enjoy this series, but PBG’s character is such an annoying little prick.

Crackers Jul 27 2025 11:05 pm Let me start with a public service announcement: if you're the type who pauses scenes to spot plot holes, zooms in to check timeline inconsistencies, or treats dramas like crime scenes—please, for your own peace of mind, skip this one. You'll just give yourself a headache.

But if you’re here for the vibes, the emotional rollercoaster, the theme, the heart, the friendship goals, and the kind of moments that make you smile at your screen like a fool—congratulations, you’ve found your next obsession.

Now, I’m a mix of both worlds. I did have a few “wait, but how—?” moments. The logic gaps? Yep, I saw them. Did I care? Honestly, not that much. Because the characters? Loveable. The friendships? Solid. The weekly episodes? I anticipate them like it’s my favorite meal.

It’s kind of like loving someone deeply—you start seeing what matters most, and the little flaws just blur out. So while it’s not a perfect 100, it’s a strong 98/100 from me. Would watch again. Would cry again. Would recommend.

Jaeseon Jul 27 2025 7:21 am Done watching episode 1 to 9, all episodes are down moments, villain always win, its really annoying dont know if i will continue watching, this kind of story/plot kdrama, will not worth to watch and you cannot think to rewatch it again. They should have pu up moments in between episodes.

SeventeenWorldTour Jul 22 2025 12:47 pm If you're a highly detailed person who takes every part seriously don't watch this because you'll get stressed out. However if you're here for the theme, the story, the fun, and how it makes you feel in general— this drama is memorable and enjoyable, so you should definitely watch. I'm both, I have lots of questions, but it matters less than the experience. I love the characters, their friendship, their perseverance, and I look up to the new episodes every week. Might be imperfect because of the plot holes, but you'll get to ignore it as you watch, just as how you see the beauty (not physical) of the people that you love and care less about anything else. So this drama 97/100.

Mythoughts78 Jul 21 2025 5:20 pm Just finish ep16.. Drama was strong in the beginning, then draggy,, then a lot of unnecessary/impossible things happened. But notice in ep15/ep16 ,, there’s a truck, full of explosives etc.. why have 5 police officer run after it? IMO, actors are a bit exaggerated again directors and writers.., and drama got boring later in the episodes,, like it was great from ep1-12,, Plus chasing 1 guy,, but the writers could’ve done better,, example, all the time Dong-Ju met up with Min Ju-Young privately, that wasn’t needed at all,, but then they chase after Min Ju-Young, through out the whole drama.. whats the point of that.. I really only enjoyed the funny humor the characters threw out there.. ‘’ ohh anyone notice how cheesy it was every time the actors had to promote something in the drama, like the kopiko coffee candy, coconut water, and the sandwiches.. lol. either way top notch actors in this drama.

Pasing Jul 20 2025 10:01 pm So annoying,why they dont have guns to protect themselves since they are dealing with mapia

z Jul 20 2025 7:58 pm the ml is so impulsive and always going head-first into situations without giving it a second thought. isn't being level-headed and rational major requirements to being a good police officer.. ? genuinely don't understand how ppl can stand watching him but ig they're too busy tearing the main actress apart to notice or care

Lord V Jul 20 2025 3:06 am Okay, drama could be shorter, but that's not that important. Can anyone help me find one song from this drama? There's one which I can find nowhere, nobody even say about this. This song were for example at the end of 15 episode. Why I can't find even the author of this song? I know it maybe weren't publicized official, but why it is nowhere????

LC Jul 19 2025 4:25 am Initial few episodes with funny scenes, thinking should be not bad watching. But getting more draggy, why must have so many fighting scenes which make it sooo boring! Baddies like never ending, will never die, always with weapons but good guys fight bare handed. It seriously so annoying watching it! 16 epi is too much for this drama, reduce to 8 should be enough. Can fast forward those fighting scenes actually to save time and frustration. Took up too much time! Watch when you are super free!

GM Jul 18 2025 9:35 am Title should be “Annoying Boy”

shevi Jul 18 2025 6:48 am Too Dragggggy! Some other kdramas w only 8eps deserve more but this deserves less. Main leads have no chemistry at all. Sohyun acting too cringe and meh. Cant believe bogum took this project. Really, 16eps to defeat mjy??? Too repetitive plot!' If u want to annoy urself, go watch this

shevi Jul 18 2025 6:45 am Too Draggy! Other kdramas with only 10eps deserve more; but this, this shouldve ended at 8eps or less. Repetitive plot, no chemistry between main leads. So hyun's acting is sooo meh. Cant believe bogum took this project. So many of them but 16eps to defeat min ju yeong?? Come onnnn. If u wanna annoy urself, go watch this

Mywoman_Yeaji Jul 18 2025 6:30 am I like the movie especially because it keeps us on our toes wanting to see what will be the end of "Min Ju Yeong".

But goshhh ... I think it dragged. I think it could have been a 12 episode series because it's just all a new twist that has them fighting and fighting.

Plus I think that Dong Ju's character didn't grow throughout the movie... At least till Episode 14. He's still hotheaded and thinks with his fist not his head. I mean we don't mind the fact that he fights but one thing that's recurring is how he fights without thinking of the consequences to him and the people around him.

The Storyline isn't bad and I think the drama is great but would have been nicer of Dong Ju's character grew and the episodes were shorter.

All in all, I'm looking forward to see the end of Min Ju Yeong

Meanie Jul 18 2025 6:01 am I am so excited for the finale of Good Boy!

Everyone is saying that Hanna missed Min Ju Yeong in episode 13. But she did not! She deliberately shot him to get his attention because her main goal is to expose him, not to kill him. What's the point of installing a body camera and asking her senior to livestream if she will shoot him from afar? It's all pre-planned.

And Kim So Hyun's character is supposed to be nonchalant, so why is everyone pointing out her facial expression? Although it's not surprising, because almost all leads who played a "non-vibrant" character receive this type of hate, Lol.

Park Bogum's role is gullible so he shines more compared to Hanna's personality, but I still hope people will stop slandering So Hyun as if she did not match how her character was written.

Anyway, it's 100% a must watch and re-watch for me! Goodvengers are amazing!

Imchopsuey Jul 15 2025 5:33 pm Ok,, let’s be real.. and this is just my opinion. From ep 1- to like I say 10, was great.. I love the funny moments and the team as one but,, it was draggy, and Dong-Ju does not need to fight like 20 guys all the time, he was drugged almost killed and then. A few days later he’s back to kicking butts again.. and really Han-na the top sharp shooter misses - Min Ju Yeong, it’s getting to where it should have ended at 12 or 14 ep. I had to go back and google how many episodes the drama had, with the all fighting in ep 13/14,, I thought 14 was the end.. But what do you all think about Kim So-Hyun acting, in this?? She’s really bad, even her crying was not so great. It’s the same facial reaction in most of her drama she plays. Emotionless, nothing great to rave about. But I’m going to finish since I came all the way and love the rest of the cast. Especially the Funny moments they throw in between.

Comets Jul 15 2025 7:12 am Not a rant. Rather odd situations in this drama where:

- Min Ju Yeong had plenty of chances to kill Dong Ju. He's giving him chance to live every single time.

- Sometimes there are guns, sometimes there's not. Drama could've ended if they fought with guns.

Nevertheless, those things makes the drama. It's just confusing to think about.

Jef Jul 14 2025 12:19 pm 10 episode drama storyline dragged to 16 episode. Too draggy and boring.

Pip Jul 14 2025 9:13 am I like Leo and Drugmom :') They're kinda tragic and complicated

Shairli Jul 14 2025 8:25 am Hope I can finish this drama. Really want to drop but really want to see the end of Min Ju-yeong.

Agree on one thing though, action for the bad ppl but comedy for the athletes aka police. Ridiculously not using their brains that much.

Sorry scriptwriters, terrible storyline, confusing characters build-up, weak plot... disappointing to the max.

Dongjuuuuuu Jul 14 2025 4:57 am Guys, would he survive? Dongju

Phoebe Jul 13 2025 4:46 pm Didn't finish I was saying ( yea yea yea I'm in the USA watching kdrama. It's the only thing keeping my sanity. Love and Peace !

Phoebe Jul 13 2025 4:32 pm I just love kim So Hyun in this drama so much, she just show talent to the MAX! I think all of the male leads used too much fist and baton but at least she made it looks so realistic. The writers should do better jobs. Park Bo Gum should have died long ago and I'm at episode 14. I know it's Fiction but come on, only So hyun acting makes sense. They better lucky I love Park Bo Gum and So Hyun so damn much. Enjoying it just the same ! Ps.did not enjoy the glasses dude Lee Sang Gi need to tone down his acting. His character is too serious ( laugh and lighten up) or maybe that's who he is in real life ! So Hyun for more action Kdrama. And for the record I'm watching it on Prime in the USA (yea years yea I know

Chae Soo Jul 13 2025 1:45 am I love episode 13! I am so happy that Ji Hanna had a longer action scene, and Kim So Hyun totally pulled it off. I am so in love! The trailer for episode 14 is exciting! I can't wait for the action-packed and reunion of all the Goodvengers! Must watch! #JiHanna_Is_Love

mahdiye Jul 11 2025 3:43 pm It was boring from the very beginning. Park Bo Gum is extremely off-putting, stubborn, and clueless and childish like a babygirl. In the early episodes of the drama you can't even connect with the 'good guy' character enough to feel any hostility toward his enemy.

It’s like we don’t even care whether the criminals get caught or not because we never connected with the main character.

And now they’re dragging it out for 16 episodes—it should’ve ended in 10."

rOb Jul 11 2025 11:47 am Why with the 16 episodes? With the main storyline, 10-12 episodes would bw enough. And i am annoyed with dong ju's actions. He always put other people at risk with his actions. So immature for a lead character.

Zeila Jul 11 2025 8:13 am Watched for Lee Sang Yi, but have to agree with others that the script is quite weak. Not holding my attention span very well. Great cast though.

Sus Jul 11 2025 7:57 am Too much gratuitous violence. Repetitive fight scenes & not only accomplishing nothing in the vague & weak storyline, but So S0 unrealistic! It’s not like it’s a super hero movie. As it’s unbelievable enough for the four olympians to take on dozens of criminals without proper backup, Dong-ju takes on a room full of ruthless gangsters all by himself, not once, but over & over again? To collect the watches to make…a point? All of the actors, as always, are very good. I think it’s better to take the time to get a great, or even good, script rather than crank out dramas. My husband refused to keep watching, I’m watching now & then & fast forwarding through the fight scenes.

Zin Jul 11 2025 6:29 am Def watch this for Oh Jungse. Superb acting.

anon Jul 09 2025 6:38 am The actor who plays young Min Ju-young was brilliant he matched upto Oh Jung-se level

mina Jul 08 2025 12:19 pm now how would they know what drug he took lol, and he clearly can be seen chased and stabbed at least try to make it realistic if something is supposed to be a tragedy dawg

mike Jul 07 2025 7:48 am bad scriptwriting. i dropped at ep2.

might pick up once this ended and watch all in a day.

Like why Part 2? Jul 06 2025 11:39 am What the H E L L did I just watch??? It was endless gory torture??

:P Jul 06 2025 7:41 am Batty theories--

-Geum Nam is the real godfather of the smuggling world and has been playing the police as an informant.

- the friendly cop is the mole in the police and he covered up Hanna dad's death.

- The bumbling police chief is entirely innocent but caught in a trap and will get shot but survive due to the new bulletproof vest.

- Shin Jae Hong fell into a trap by Min Ju Yeong due to needing money and betrayed by mistake

- Oh Jung Gu was Oh Bong Chan's son and is plotting to avenge his father and establish himself in the place. He might get the other three men to destroy or kill each other.

- Baek Suk Choon's right hand man will betray him.

- Hanna and Sarah were Leo's daughters or nieces and the neighbourhood store granny is the mother.

- Or the mysterious woman who worked in customs is the sister.

- Drugmon is DEA. Or Leo is a Korean undercover in Russia pretending and Mama is his handler.

- Ji Ho Cheol was undercover in Russian mafia. Or Hanna eomma has ties to Russia and will end up with the informant Sergey.

- Man Sik will be the one hurt badly and SCIT will reunite as avengers. Or his daugher and wife will be in danger.

Absolute bad theory--

- Jae Hong will be badly hurt and his family target

- Dong Ju will go into a coma due to punch drunk syndrome and FL and SML will look after him

defakhairy Jul 06 2025 5:26 am Goog boy.. good movie.. good romantic

Protect the Pawnshop gang! Jul 05 2025 12:56 pm My 1 greatest fear about Jae-hong being in danger has returned with the next episode preview (ᗒᗣᗕ) The shadow looks like Leo with a gun. This episode was cute because of Gwang-se and Sergei. I like Oh jung-se's backstory.

Russell Jul 05 2025 11:37 am Is Oh Jung Se in Everything??? It's hilarious that practically every new drama I watch now he pops up in. Lol!

Like why? Jul 03 2025 3:56 pm I don't get the point of why uri Good guys have to suffer so much just for a payoff- especially physically- Dong-joo has head injury complications that keeps getting worse and they are amping up deathflags(plz the drama doesn't have the tone to be ktrauma ending), Hanna has Meniers ig and Jong-hyeon had a ankle injury that got worse & ptsd from being stabbed during the match that keeps him from fighting to his potential & now his shoulder had two consecutive major injuries. Man-shik keeps getting tortured and abused. Jae-hong is the only one nothing happens to and it worries me but he is almost a mascot character same as how he is for the traffic department.

Harere Jul 02 2025 10:30 am Episode 9 the worst episode. Bad plot ever.

So Much Filler Episodes Jul 02 2025 9:11 am This could be shorten to 8 episodes lol So much filler eps. They can actually target the mayor by using the public opinion lol. Could have ended soon

Nana Jul 02 2025 8:06 am The scene with the bald informant and Mama's boy's Mama's call is one of the funniest things ever. Mama is the ultimate boss!

Nagihan Jul 02 2025 4:03 am One of the best ones I've seen. It's great to see Park Bogum in such a role. You are a great actor, Bogum. We're always keep supporting you from Türkiye. More love to Good Boy Team, love you guyss!!

anonymous Jul 01 2025 2:41 pm I can't believe Heo Sung Tae is the same age as Oh Jung Se and Go Joon

FilaWhite Jul 01 2025 2:35 am I have watched a lot of Kim So Hyun dramas but this one made me love her a lot. She's so cool!!!

gyuandrain Jul 01 2025 2:33 am I didn't find it interesting the first episodes but really glad I stayed because I love them so much now ?

I love their team, I'm gonna miss them when this ends.

Hanahana Jul 01 2025 1:43 am I don't mind it having 16 episodes though. I'd get to see them for a longer time.

Jaya Jun 30 2025 2:23 pm I'm sorry good boys, but I'm obsessed with the baddies. Drug Mon is the cutest, Russian cat is the hottest, Baldie is the funniest. The ordinary customs psycho is the baddest vegetable-hater but I dislike only the ex-coach the most. Unfortunately they always kill the more interesting ones ToT especially after they switch sides or turn against the final boss

seokjinie Jun 30 2025 10:32 am The plot is getting too long, they could've end this at 10 or 12 eps, but still great, park bo gum in an action role

Ninawm Jun 30 2025 8:43 am Is it just me or anyone else annoyed at the ML’a reckless and hot headed behaviour ? his fists are always quicker than his brains .. i really wish he thinks before he acts. Maybe research the criminal more before accusing him with all the things he did do so that he can have irrefutable evidence against him.. I know its just a drama ?

Zee Jun 29 2025 2:51 am I really love this drama. The first few episodes were all heart-fluttering, despite the conflicts. I love PBG and KSH scenes together. Although I hope to see flashbacks of KSH and LSY too! Now that we're on the intense scenes, I'm still loving it. The staffs did amazing, it seems like we're starting the "dating" era, then they introduced the "non-romance" episodes! I love it!

Jojo Jun 28 2025 4:52 pm Start of Ep 9 was just stupid, nobody cares for your boxing skills, pick up the pipe and beat them over the head with it, and the girl she had a gun and couldn't even beat them, lol. This fighting scene was the worst I've seen in a while. LOL

The only thing the girl did right, was sacrifice her clothes for a "Hansel & Gretel" move, im surprised she was still moving after that, she would have been freezing her neh-neh off, lol. I still love the cast, they make me laugh, its the script writing I hate the most.

Dongju Jun 28 2025 7:36 am Dong ju won't d*e right?

Why does he keeps on getting dizzy?

Mythoughts78 Jun 27 2025 11:34 am This is great! I can’t I can’t… I laughed from episode 1-8. If you have a sense of humor and want to enjoy some laughs, you will love this. Every actors n actress portray their character perfectly. I love the, “ who has a flat tire” but buys a used tires? And the stare down between Dong-Joo and Jong-Hyeon over Han-na, little stuff like that is funny. A must watch for sure. Very refreshing, and love the chemistry between Dong-Jo and Man-Sik.

Sheila Jun 27 2025 8:54 am @Jojo have you been watching? Man Sik and Dung Ju couldn't possibly rescue the team with their car because the tunnel is blocked with people lol and Jae Hong with RUI team was ambushed. Even after Dung Ju and Man Sik subdued those men in the front, they eventually got up so Dung Ju left Man Sik to go further. Unless you are talking about other characters, I can't really understand such dumb writing you're referring to.

Anyways, I'm loving this. Not a fan of any of the leads but I like the action. The fl is strong and although she got captured in the end, she didn't go down without a fight haha. I don't really believe she could take down all those men by herself but I really love how she could last that long. And Dung Ju is strong too but he doesn't get rest. After that warning from the doctor, he went to receive punches and hits from here and there. I really wish it will be a happy ending.

anon Jun 26 2025 9:53 am Kyung-Chul should be the traitor please not Jae-hong

Jojo Jun 23 2025 1:41 am Ive enjoyed it, up until i was watching Episode 8.... the fight scene where they try to obtain the container in the tunnel was really pathetic, whoever wrote this part of the story was stupid... I mean why not stay in the vehicle to protect themselves while they go in and rescue their team in the tunnel? Wasted energy fighting ppl when they should have just used them for target practice and run them down with the car - this is what happens when you exaggerate the script, and it ends up looking dumb.

kiky Pertuz Jun 22 2025 5:14 pm I was really enjoying this drama until episode 7 came and they used The Our Father prayer as well as the blessing of oneself during a murdering scene. This is seriously offensive to Christians especially Catholics. That was so sad that they did that.

Yeruchii Jun 18 2025 12:42 am Kim So Hyun is an absolute badass here! I hope she gets more popular and recognized here!

Es Elle Jun 17 2025 8:30 am Highly recommend this drama, it has all your genre in one. It’s refreshing to see Bo Gummy play a part like this, and he’s totally killing it! Can’t wait to see how this drama unravels, and love that it’s going to be 16 episodes!

Love Jun 15 2025 9:58 am Love this drama. BoGum in police uniform is so Hot! What I'm worried is sad ending for Dong Joo. He keep getting hurt and he always take it lightly. Really hope I was wrong because this drama need a happy ending. Jebal!

Donny Jun 12 2025 8:56 pm Park Bo Gum usually always looks cool with an idol aura but here he become silly and reckless. Love to see him playing this character. I almost forget he is a very handsome guy. His arch enemy character played by Oh Jung Se. This guy could be anything or anyone. We can sense a creepy aura only by the look of his eyes. It is very enjoyable watching this movie since I can feel angry and also funny at the same time. The director and screen writer I think do a great job mixing it.

Rainy Jun 12 2025 12:56 pm This drama is so good.

Hara Jun 09 2025 11:30 am I'm in love with this drama, I can't wait for the next episodes.

Park Bogum and Kim Sohyun have it Jun 08 2025 5:16 pm Whenever Dongju and Hanna have romantic scenes together, I can feel the tension. It's like what I'm seeing is a real people (not actors) developing a romance. I can't wait for more.

Mansi Jun 05 2025 2:40 pm Like always , KimSohyun is nailing it. And bagging all the praises

Sally Jun 04 2025 11:55 pm I heard that this drama is getting positive feedback in SK. The cast is pretty cool though, Park Bo Gum, Oh Jung Se. Hope the script is good Finally, Kim So Hyun can get the attention she deserves.

Will go watch this tonight...

Anders Jun 04 2025 3:13 pm There are a lot of famous actors in this show, but the script is boring... In my opinion, the first 30 minutes of any show is vital to get the viewers attention but this show wasn't even remotely able to do this. The story jumps seemingly random from scene to scene, and made me lose interest completely, and don't get me started on the stupidity of the characters - it's beyond believable. - I don't know what genre this show is supposed to be?

Ahjumma Jun 04 2025 12:59 am Loving this all star cast drama! Most of my favorite Korean actors are in it!

Dayah Jun 03 2025 7:51 am I love this k-drama already

Good Boy Jun 02 2025 10:09 am ahh when i hear the doping issues i just think windbreaker ahh love it

Yeruchii Jun 01 2025 11:35 am I'm just here for Kim So Hyun <3

Chloe Jun 01 2025 8:46 am Lee Sang Yi is super cool, cant wait for him to be a ML in a drama. I liked the first episode. PBG is versatile, I enjoy watching different angles of him.

Russell May 25 2025 12:34 pm I am looking forward to this after the confusion of Heavenly Ever After, the drama before this on the same station. Lol

Nan May 17 2025 9:23 am Are we watching it for Park Bo Gum or Park Bo Gum? Yes. For both.

Yeruchii May 15 2025 7:54 pm Finally, PBG and KSH in one frame! I'm so excited for this!

Miri May 01 2025 10:58 pm Can't wait to see PBG, KSH and Oh Jung-Se act together in this. Oh Jung-Se is in everything these days, and completely inhabits his characters. They're all so different from one another.

Izzie Apr 29 2025 10:14 am omg!! I'm so excited to see Park Bo Gum and Kim So Hyun in a drama together!!!

Nervana Apr 28 2025 12:26 pm Finally! it is said to be released on May31, been waiting forever for this drama

azie Mar 24 2025 12:04 am can't wait to watch it

Jillibean Mar 09 2025 3:55 pm Great cast. Will definitely watch. :)

Sudha Malhotra Jan 24 2025 2:33 am Looking out for it.. Bogumny is one of my favourite actors across all nationalities! ‘Good Boy’ is the perfect title for him! All the Best!

Nunu Dec 23 2024 7:15 am Urii Sso and Uri Bogumii!! I am waiting uu two?? Kajja!! Fighting our new couple?

Hadiss Nov 14 2024 12:56 am Soo(Kim so hyun) you are so good and you are best in Korean

LEESangYi_Fan Oct 16 2024 1:13 am Im here for my boy Lee Sang-Yi!

Beena Oct 13 2024 5:36 am Waiting, waiting, waiting… park bo gum to appear ???❤️??

Feb Lee Sep 14 2024 2:29 pm For those who are wondering the premiere is Nov. 30. 2024.

Libay Aug 27 2024 6:16 pm looking forward and excited for this series with Park Bogum and Kim So-hyun! hoping that this will be shown on Netflix...pls!

Hazel Aug 09 2024 10:46 pm I can't wait to watch kim so hyun new drama again with park bo gum im so excited ?❤️?

Fansof_heo Jul 31 2024 3:56 pm Heo Sung-tae as Go Man-sik! I can't wait to see our bronze medalist in wrestling! ♡♡♡♡♡♡♡♡♡♡♡♡♡

seokjinie Jul 23 2024 8:23 am sooo this is why bogum is building up his body

Yeruchii Jun 21 2024 1:14 am This is what I like about KSY, she never does the same genre. It's always different everytime. She explores and grows each time as an actor. So excited for this drama.

kirsten Mar 24 2024 8:11 pm It's good to know how the writer chose Kim So Hyun again to be one of the leads in her series. Let Fight Ghost is a fun series.

kirsten Mar 24 2024 7:30 pm Excited to see KSH in this type of role for a modern drama. Her dream role is act as a doctor in a show so I think this is a good start.

Daphney Mar 24 2024 7:09 pm Couldn't be more excited for this series. Can't wait to see Ji Han-Na and Yoon Dong-joo. Hope this series have decent storyline, choreography and action. This series seems unique based on its description. Fighting team

GoodBoy.

Kei Mar 21 2024 11:25 pm Great to know the tags don't include romance or romcom troupes though when it comes to KSH romance may still be included. Excited for this series!

Ai Mar 21 2024 11:03 pm Police and action-comedy are solid genres if combined well in the narrative. This writer had experience with the later. The storyline matters plus the casts themselves. Couldn't wait for this to be aired.

Shinyshiny Mar 03 2024 10:11 pm Omg why did I just found out about this now my girl sohyun never disappointed

Gg Feb 27 2024 7:03 pm The casts are already complete! So so excited for this drama, all casts are perfect, finally we can now watch bogummy and soyuni. So hyun would be cool on her role as goddess shooter and bogum is hot as boxer. A very super new plot this year! Super duper excited! Pls. Release this in Netflix pls . A lot of international fans are waiting this drama. The word Avengers is super cool and a blast, when is the announcement of it’s relese pls? Cant wait already:(

Tin Feb 27 2024 7:12 am Finally, kim so hyun and bogummy, so excited to see them both onscreen. The plot is also interesting and something new in kdrama. We will definitely watch this. Really hoping that this will also be aired in Netflix pls! Im a fan of both so hyun and bogum. Both good actors with nice personality

Benny Feb 27 2024 5:18 am So excited for thier tandem! Hope this will also be aired in Netflix. This is one of the most unique and total package kdrama with action, thriller, comedy,drama. Hope they will be focused more on action and solving cases. This will be surely a big hit! Hope this will release early this year so so excited!

moksolhee Feb 23 2024 6:45 am One good thing about Sohyun is she chooses dramas that are all unique. From twin sisters in Who Are You, the drama about love alarm application, a woman who can hear lies and now this one (Good Boy). I haven't heard about drama that talks about athletes who became police officers which I think is very unique.

Kaoro Feb 22 2024 11:39 am So hyun and bo gum are the best choice for this role and this is the best tandem and hopefully one of the best kdrama for 2024 considering its unique plot story and many characters, hope they add up good actors for the remaining casts. I am super duper excited for this drama, hope there will be more action, thriller and a lil fun comedy om this genre. Thank you for choosing sohyun and bogum as maim casts:)

Vin Feb 19 2024 5:42 am Kim so hyun is so perfect for this role, she already played an assassin in RWTMR. Super duper excited for this two tandem specially for kim so hyun. @kira,FYI kim so hyum dras are almost have good high ratings, goblin, school 2015, River where the moon rises¹ The Tale of Nokdu, emperor owner of the mask.

Chuzu Feb 19 2024 5:36 am This is the best tandem so far for 2024. Hope this will be aired in Netflix. We are so so much excited for our one and only so hyunni. She is a very good actress, she already played as assassin im RWTMR. Hope the writers and Directors will be focusing on action special mission rather than any romance. This is your time to shine Kim so hyun and Park Bo Gum. This is your year to shine. We will always be supporting you both specially kim so hyun

Shairli Jan 28 2024 10:41 am Skeptical on story & actors chosen but looking forward.

marusha Jan 27 2024 5:37 am wow a nation's boyfriend with a nation's little sister in one frame. finally!!!! the pairing doesnt disappointing at all.

moksolhee Jan 24 2024 6:43 pm @Jajang Lol have you seen Sohyun in River Where The Moon Rises? She fits the role as an assassin and princess at the same time, and Good Boy is an action drama so the role fits her. She just looks so young because of her full bangs in My Lovely Liar but without the bangs, she looks matured. Y'all are complaining as if Good Boy is a romance drama. And of course the production will probably style her as 25+ police officer, unlike in My Lovely Liar, her character always acts bubbly and cute that made her look like a little girl.

jan Jan 22 2024 4:49 pm Kim Sohyun fits the role. With her past experiences in action dramas, she will surely give life to this character well. Can't wait to see her nail this type of character.

Jajang Jan 21 2024 8:30 pm Cant they cast a more mature looking girl? She's pretty but looks like a little girl.. :/

Stiff Jan 17 2024 7:16 pm Can't wait for this drama. Hope it has a promising supporting actors as well

Kim Jo-Jo Jan 16 2024 1:32 am Finally..... can't wait!!!!!!!!! ❤️❤️❤️

Kat Jan 15 2024 3:28 pm Their visuals are crazy

ai Jan 13 2024 10:26 pm Excited for this pair. Hope this is the start of Kim Sohyun being paired with established actors.

NJNJ Jan 11 2024 8:56 pm Can't believe this is happening ? After how many years of Sohyun's struggle, she finally gets paired with an actor that has the same caliber as hers when it comes to acting. Not trying to be mean but mostly, she gets paired with rookie actors or idol-actors which is so disappointing sometimes because Knetz are so harsh to kpop idols turning into actors and Sohyun will not grow if she is consistently paired with them but honestly speaking, Sohyun has overflowing chemistry with rookies or idol-actor like Taecyeon, Sungjae and Hwang Minhyun. I don't mind if Bogum-Sohyun will have a siblings chemistry since Good Boy is a non-romance drama. As long as it has well-written plot and lots of action scenes and crime solving, Im Seated!!!

I hope Oh Jung Se is the additional cast for this and it will be perfect. I hope writers and producers will not waste the talents of these two. I hope they promote it well and put it to Netflix for wider audiences.

I have high hopes for the combination of good writer and PD especially Sohyun had worked with the writer before in Let's Fight Ghosts, and she had lots of amazing action scenes there. This time we will see Sohyun in different light. More mature role, more physical movement and Sohyun holding a gun is what I am anticipating for. Fighting Good Boy team ??

Seu Jan 11 2024 7:53 pm Just realize the writer is the same writer of Let's Fight Ghost. Sohyunie can do this well.

Kate Jan 11 2024 7:51 pm KSH's role is nice as well as Bogum's.

ana Jan 11 2024 12:29 am Can't wait for this series. And the plot sounds promising.
