Family Mar 05 2026 5:56 pm The only person (MC) that would be acceptable if he says he wanted to born on a different family

what a mom Jan 26 2026 12:58 pm what a mom, double down on being awful is the way to go.... yet she wonders why his so called son hate him. perfect korean role

Sone Nov 25 2024 2:01 am I stan Lee Goon and Ju Yeon, I want another reunion for this couple they both gorgeous...

Leila Nov 10 2024 1:41 am I thought this drama is bad but not actually, I enjoyed it a lot, the leads are beautiful and I like their acting they are good, thanks and I never listen in the bad comments, I recommend this drama for sure

Jillibean Oct 19 2024 11:26 pm I enjoyed this drama quite a bit, and it was so nice to see the chemistry between the leads, and the writing kept me guessing what would happen next, which I really like! I get tired of dramas that are too predictable from the beginning. This one kept me guessing about the various characters and how they would react to one another. My only criticism would be I think this drama would have been better condensed into twelve episodes instead of sixteen. It was a little drawn out, the various storylines could have been resolved more quickly.

Nikky Oct 12 2024 10:47 pm I'm glad Lee Goon and Joo Yeon will end up together they are my favorite couple from the beginning up to the end, this drama is not bad as others say, maybe there are complicated parts but I still pleased that the FL and ML were meant to be and the ones who ended up together, although the others have high expectation in this drama, me I really understand every characters description, I don't care about the negative comments, I'm here to appreciate everybody's effort and their acting is believable, I hope to see more dramas from Kim Jae Joong and Jin Se Yeon in the future because they got my heart in this drama, their chemistry is really impressive and pleasurable, I will also add them to my favorite couple

Dexter Oct 05 2024 8:24 am I like this and the chicks are thin and clean, but the music adds nothing... disappointed ?

Mae Sep 25 2024 2:40 am This drama may not be the best but the cast acting is good and enjoyable to watch, it's sad that this drama is over, I really miss the moment when I'm always waiting it every Friday and Saturday, compared to other cast in drama, BME casts are credible and has perfect chemistry, I will really miss them (⁠╥⁠﹏⁠╥⁠)

A Sep 21 2024 8:41 am bad writing, bad ending, not much romance. ep 16 only has 2 mins of FL ML screen time without explaining what happens to their relationship after 3 years of fast forward, no dialogue, just nothing. waste of talent of actor and actress

blueblue Sep 16 2024 8:02 am It's been forever since I see KimJaejoong on screen again. I almost forget that he was so good in drama Triangle. I love his acting here, from the depressed Lee Goon into goofy narcistic sincere guy. I really feel bad for his character Lee Goon, he is an absolute victim here. After watching ep 14, I do feel worse for Lee Goon TT I wish he will find peace at last and live his life to the fullest, with or without Jooyeon. I was so mad with the parents, how come the parent glorify their younger son only just because he is healthy one, become top tennis player (he's replaced though), and bring glory/pride to family. What about Lee Goon? Is he not their own son too? How come they treated him more badly than their dog, wtf!!! Lee Shin is a redflag for sure. After explanations and flashbacks about what really happened here and there, I had zero empathy for him. How he treated his brother was a big No! For the doctor, I had mixed reaction for her. She was so bad at the beginning, specially in a runaway mouse scene, that's not how a doctor reacts to patient or anyone in the first place. But after she got involved in Lee Goon's life, she was cute though with him. But, when she intertwined with Lee Shin, it's really annoying too. For OST, KimJaejoong voice in "It's okay" really enchanted me. His voice is so deep in emotion and so sad, it feels like he sings the song for Lee Goon. I can hear it has so much feeling into it. I cried a lot when I listen. It's in my spotify list and I keep replay the song over and over. In conclusion, I will finish this drama in hoping Lee Goon has his own life, peaceful and happy.

Parents Fault Sep 13 2024 6:14 pm Idk, maybe I'm too biased this time but I just can't empathize with Lee Shin despite revealing his feelings this episode, living in the shadow of Lee Goon (watched similar antagonist storyline like this & I usually could sympathize but not this time, they made the brother character too annoying).

For real, he denied wanting his brother's life but didn't stop himself and still not stopping to pursue JooYeon. He did not step up whenever their parents treat Lee Goon badly, for fvck sake's he treats him badly, why, because he resents him for how his life turned out -- but for real, he enjoyed the privileges the life-he-don't-like brings. He's not happy when his brother woke up confident and not have inferiority complex & victim mentality he was yapping about before the incident.

The doctor is stupid too. There's an obvious feud between the brothers and she kept on making herself be part of it. Stupid experiment too, I like the parallel when SaeYan's mom say something about bad memories but she couldn't see it. I empathize with SaeYan though. And maybe that's it, it's no use to erase bad memories. Psychology should have different approach so her causes are just not it.

It's the parents fault. They are hugely responsible for this. I doubt they'll show them suffering any consequences, or show they're repenting, because it is a kdrama afterall

Also I'm no longer rooting for the lead couple though they'll most likely end up together. I want Lee Shin to live his own life, happily, free from the people he already know and travel, live far from them and meet new good people later on. Even an open ending him traveling far would be better at this point.

Kirahae Sep 13 2024 10:00 am Joo yeon doctor is really annoyed, don't not know what to choose between big brother and the small brother. Somehow i wanna Lee Goon with sae yan or si on. Lee shin redflag. Director please repair your storyline as its wanna end already

Nimi Sep 10 2024 12:20 am Please don’t blame the brother,I can’t hate him though maybe because I started this because I’m a fan of Lee shin. He grew up living up to his brothers expectations,it’s like he grew up living the kind of life he never wanted cause he does not want to disappoint his parents or because his brother got hurt because of him. Lee shin is sad enough as it is,the writer should have given him freedom and his own love life,I don’t understand why they had to make him into a villain. The boy is not happy too. I blame the writers!!!!

Kay Reeves Sep 08 2024 9:37 am The only reason I am not dropping this drama is because I want to see the aftermath of Lee Goon getting his memory back and I am hoping and praying to whatever higher being out there is to somehow make the remaining last episodes in a full revenge drama and Lee Goon being successful and happy like a big manager or owner of a big agency without any of these people(the parents, the doctor/female lead and Lee Shin/the brother) interfering in his life anymore. He is the only victim I have seen in this drama and hope that the writers/directors listen to the audience once and make him happy and strong alone.

Dileep Kumar Sep 07 2024 6:36 am I love the chemistry between Lee Goon and Kyung Joo Yeon, I wish they both get together by final episode, but whenever I see Lee Shin, I feel sad for him and also I get angry on him.

Raquel Labargan Galvez Sep 07 2024 4:16 am I love movie the Lee Goon and Yeon Yun and rest of the cast . I wish they wiil end up together. God bless and more more power. Keep it up??

sf Sep 06 2024 12:32 pm Lee Shin and Jeon Sae-Yan are the most annoying characters in this drama, at least for me. They always appear when nobody wants them to be there, and they stop, without saying sorry, the conversation between the main characters. 16 episodes of this drama are too much because the action is absent, it is about nothing, lacks of substance, boring.

Johana Sep 04 2024 2:31 am Lee Goon and Kyung Joo Yeon looks perfect match made in heaven they give me butterflies in my stomach every time they interact together, I love their cute chemistry, they looks like a real husband and wife, I don't care about anything, I just focus in main couple story, this drama is for me.

irene Sep 03 2024 11:28 pm i dont have a problem with the actor's acting

But I Do Have A Problem With The Weird Storyline... it's so confusing to have lee shin pursuing the juyeon (female lead) outwardly in front of his brother cuz i thought Lee Shin was also the one trying his best to not steal his brother's lover again... yet it keeps portraying them fighting over the girl which i thought Lee Shin was really adamant about not doing...

so confusing.. so much headache..

promising story line and Actors But the script is just messy in little ways i've noticed.

it's not super realistic At All either so the whole thing comes off as almost weird/ unbelievable but i like the leading 3 actors acting nonetheless.

Pia Aug 31 2024 5:26 am I'm very hooked in this drama now, no boring episodes this is one of my favorite romcom drama nowadays.

Mi mi mi Aug 31 2024 4:36 am I am dropping this drama I am tired of the whole brother's life one day script with the other brother taking everything plus the sanity of the other to later a happy ending and all whatever nonsense. I need reality rom-com that don't mess with one's mind. I will rate it a 4/10 cause I liked the whole memory erasing thing but the rest is flawed

Hannah Aug 29 2024 3:59 pm This drama is really good. I highly recommend it to the people who love a good rom-com.

Goon Aug 29 2024 1:34 pm They all pretended to taking care of LeeGoon after what was happening to him at the river. Resides that, everyone in this drama are selfish especially Goon's mom. Let Goon facing all the hardship alone. Gpon deserves better

Yoona Aug 29 2024 8:56 am Lee Shin is so full of contempt. After all he's done, he doesn't feel guilt and even wanting to take the doctor, even if she's not the 1st love, if only he cares about his brother he knows it'll affect him. Also, the doctor should be smart, why was she acting to stupidly oblivious towards what's happening b/n the brothers (again regardless if she's the 1st love or not, it will entice the same emotions), so why is she not setting boundaries. I want to blame the parents, they surely have a big role to why their sons turned out that way, but I feel more annoyed with Lee Shin alone. Feel like Lee Goon would still forgive him coz that's the kind of brother he is.

I hope Lee Shin doesn't end up with anyone, with his current attitude and values, it would be a pity if ever he ends up with the real 1st love of Lee Goon or her doubles partner.

Kelly Aug 29 2024 1:05 am My new favorite drama of 2024, like the acting of the cast and I feel the vibes of 2016-2017 in this drama, luckily I found it and my drought has gone. Everyone try to watch it, don't listen to the haters, this drama is very 2x entertaining ♡⁠(⁠>⁠ ⁠ਊ⁠ ⁠<⁠)⁠♡

Jaey Aug 28 2024 7:59 pm I love this drama... My fav

Queen of bad memories Aug 28 2024 5:00 pm I hate Lee shin so much. Is he going to take everything his brother has .. and why is ju yeon so oblivious.. can’t she tell Lee shin likes her and set the same boundaries she set with goon?

mill Aug 27 2024 2:56 am This drama is my favorite now. The leads are beautiful and handsome, I will recommend this drama for everyone...

koko Aug 26 2024 9:04 pm not recommended

lee goonn Aug 26 2024 9:04 pm The doctor’s so manipulative (they and their crew end up in jail for malpractice), and they still claim to be Lee Goon’s first love. Even their sibling is a bit off…But it's the parents, especially the mom, who are the most dangerous, leaving deep scars. Lee Goon, you deserve happiness—ditch them all, especially that doctor!I can't stand this storyline—it's full of massive red flags, and somehow, these red flag characters are the main leads

Chelsea Aug 26 2024 5:58 am Loving this drama so far. It's so hilarious and cute.

Jinki Aug 25 2024 4:31 am I'm hooked in this drama so far, it looks like I can complete it because I like it so much!

Ryunami Aug 24 2024 9:57 pm The first 2 episode were highly cringed i decided I also need a memory eraser LOL no words can properly explain my thoughts but I dropped this after trying watching two episodes.

rei Aug 24 2024 10:29 am Honestly, the male lead is such a Cringe. I love JSY & LJW together!!! Second lead syndrome strikes once again. :( So gorgeous & handsome!!! <3

Gracia Aug 24 2024 1:57 am This drama brought me out in kdrama slump, finally I found a drama to follow, since this drama has not been completed yet I'm still fine for FL and ML, whenever they have a scene together they looks cute like a sweetheart, I hope to see them to partner in another drama they both handsome and beautiful in my eyes, I love this actor and actress ???

hana Aug 23 2024 9:22 pm on my opinion, the doctor doesn't deserve lee goon!!!!!!! she is the cruel one, sHe was super rude, especially in the beginning, and I still can’t forgive her for that. Even his parents were terrible. There’s nothing good in this drama—it’s all red flags. Lee Goon, instead of chasing love, you’re better off living peacefully on your own.

Lina Aug 18 2024 6:52 am Jin Se Yeon is so beautiful and cute in this drama, I really like her looks and comedic expression, she is so good.

normiee Aug 16 2024 1:41 am Hyeji looks sm like Seyun

Ninda Aug 14 2024 12:04 pm Can't wait my Friday n Saturday!! Jaejoong oppa so hilarious n loveable, I hope his bad memories never comeback and please happy ending too???

Vion Aug 13 2024 7:07 pm This is drama that I need right now, every time I watch it I am always happy. This is highly recommended to those who like this genre. It is perfect to watch in any season, I love it so far....

Chy James Aug 13 2024 11:41 am This drama sucks

Jenny Aug 13 2024 8:34 am I really like this drama, FL and ML has good visuals and acting, although their first meeting was not good due the bad circumtances and FL still cold to ML but everytime they meet together, their chemistry is palpable and overflowing and my heart is also beating, I was impressed by their beautiful chemistry ❤️❤️

ThisSuxBtw Aug 12 2024 11:11 pm Wow 1st episode and I already hate the Parents

Xixiahn Aug 10 2024 6:32 pm Ohemgeee! Jaejoong Oppa. I have been waiting for your next kdrama and here it is. It's so great to see you again.

Lala Aug 10 2024 4:52 pm I'm on 4th episode and I must admit that I can't predict what would happen next.. it's exciting to wait for the next episode tho it's gonna be a long week for meeee.. Lee Goon really makes me laugh out loud starting from 2nd episode lol I was stressing out watching him suffered in 1st episode but then he became someone with overflowing confidence and like a part-time comedian right after the surgery.. when he cough out "frugaller" towards dr teo I burst out laughing ?? then I replay that part and see the nurse has already broke out of character too..

xan Aug 10 2024 6:08 am lee jong won is so handsome like tf bro

Alaska Aug 09 2024 12:44 am This drama is really good and entertaining, I like it so far the cast are amazing, they acted their characters well.

Bi Aug 08 2024 11:41 pm I know Jin Se Yun since Doctor Stranger but while watching the first episode, I was a bit distracted because I always feel or remember someone same vibes like her and I can't identify who and why she is familiar. but when it came to episode 2, I finally figured it out. She has the same vibes and voice as Karina from aespa! I can finally watch in peace!

Zoe Aug 04 2024 6:33 pm Jaejoong is back! I’m so happy to see him and hear his angelic voice. ?

King Aug 04 2024 7:27 am I like it so far. Already hate the family. Wonder if there will be any redemption. The parents are awful. I wonder what's the true nature of the brother.

sf Aug 03 2024 8:56 am His low self-esteem is more because of his parents' attitude toward him, not because of his bad memory.

Amy Aug 03 2024 3:14 am Great to see u in your new kdrama Kim Jae Joong
