Plot Synopsis by AsianWiki Staff ©

School teachers have a hard time to discipline students and they often don’t even have the will to do so. The authority of the teachers in the classroom breaks down and this causes serious social issues. The National Assembly and the Minister of Education passes the Amendment to the Act on the Protection of Teachers' Rights. With the passage of the law, a new government organization, the Educational Rights Protection Bureau, is formed. Na Hwa-Jin (Kim Moo-Yul) belongs to the Educational Rights Protection Bureau. He is sent to a problem school as a supervisor. There, he can educate the students without any restrictions or limitations.

Trailers

Comments

Debonair Jul 20 2026 8:16 pm Oops, got cut off. Going back, the characters are perfectly casted. Thank you once again, the staff and all involved in the making of the drama.

Debonair Jul 20 2026 8:09 pm I’ve watch a lot Kim Mu Yoel movies and dramas, he is precise in the character roles he plays, very versatile and debonair which ever is given to play. Whether a villain or a good guy, he is great. I do prefer him as the lead good guy and comedy film. Also Lee Sung Min is excellent actor,practically watch all of his films, never a doubt, this actor can make you laugh or cry, just love helm.

Chocolate love girl Jul 18 2026 7:45 am Please put additional cast Yang Ah-Reum as Park Soo-Jin episode 3

PP Jul 15 2026 1:16 am I always watch Jin Ki Joo's movies because the story and her acting good But why does in this movie her acting to much over.make me ill feel ? I actually chose this movie because of her and Lee Sung Min.

Ddeonu Jul 03 2026 9:31 am Wow, what an amazing drama. I really like all the actors in this drama. This drama also reminds me of Taxi Driver. I was actually not interested in watching this. But because of the advertisement where RAP's mouth was full of curses from HanRim, I was immediately tempted and I just finished watching it. It's really cool. I think their revenge method is based on the perpetrator's actions towards the victim. So the agents did the same thing. Wow. I was emotional, laughing, wincing, and also really sad. I really can't wait for season 2 to arrive. My rate is 10/10

Hiro Jun 28 2026 7:04 am As a teacher, this is so satisfying to watch! Definitely recommending this to my co-teachers. ? Off to Episode 2! ?

Love LAMI again Jun 25 2026 7:50 am I think this is one of the most K-drama who is get more and more lover... 10/10

Noonim Jun 24 2026 10:51 am Love Love Love this drama~! Must watch! The cast, storyline was great! From our heroes to the villains, everyone did an amazing job. 10 Stars!

molly dash Jun 21 2026 9:52 am great drama !!

waiting for the next session !!!

Nik Jun 20 2026 5:26 pm I've just finished this drama a moment ago.

After watching The WONDERfools I didn't think I'd see another blockbuster drama that soon, but then I decided to watch Teach you a lesson. And wow, yeah, I love it! I know it's based on reality, but I often wondered how close to reality it really is, for example: a place like the tech school. Was that really close to reality? I'd really like to know :o

But what I want to say after watching this drama: I would Love to have such a system change here, too. An official organization that cleans up all of these problems and helps to make students go back to training their brains. We clearly need more brain when I look at the world ...

Fantastic cast, acting, writing, camera work, humor and everything else. It's never boring, it was a pleasure to watch! And I also Love revenge dramas, I'm such a fan of Mobeomtaeksi already :)

I really want to see a 2nd season!

Oh, and also: if there's S2, give Jin Ki-joo more screen time, I love her screaming ;)

Notice Jun 17 2026 9:37 pm I notice how pretty smile, cute Ha Young is.

Mel65076 Jun 17 2026 6:10 am This drama is woww... Superb.. I think kstudent can relate with this. So sad about kindergarten teacher.

P.O s acting mucchhhh better now.. He can convey his role perfectly... Sorry to say... For me.. Jin ki joo acting is just screamiinnng.. Bit annoying..

trebuchette Jun 16 2026 5:21 am Ga Yun's character is so badly-written! It's actually so stupid & naive for her to think that she can handle Gyu Cheol's problems on her own. Can you imagine all the secrets she kept from her own fiance, just to protect GC. This was the only complaint I have. I mean, I guess we have to thank her naivety because if she used her brain in the first place, we wouldn't get the ERPB.

Ako si Jisoo Jun 16 2026 4:56 am Bruhhhhh Episode 2 and 4 are my favorite Episode, sooo many satisfying scenes, Hoping for season 2,3,4,5,6….. pleaseeee give us more season we’re willing to wait

Yerimshi Jun 16 2026 4:53 am This would be the best drama in mid 2026!!! We badly need season 2!!!! It reminds me of my fav drama Taxi Driver kudos to all the characters and actors on this showww. The main male lead is so damn hot especially on Episode 2!!!! Cant wait to watch s2 Kim Mu Yul’s SLAAAAP is so damn fine HAHAHAHHAHA

azuki Jun 15 2026 4:12 pm i loved it!!!!

TYAL Jun 14 2026 1:59 pm One of the best series! I absolutely love the actors, the plot, the staff, the director, and the writer, everything is perfect. Highly recommended! Please give us Season 2, 3, 4, 5…”

Cecilia Jun 13 2026 11:08 am Darn great drama!!! Don’t miss it ❤️❤️??❤️❤️??

Enjoyed Jun 12 2026 9:55 pm Excellent stories, at first I thought it would be just another bully school stories. This has extra context that kept our interest throughout each episode, well written, and lots of good humor, too. Each of the four ERPB group characters role were excellent, and deserve an AWARD. I applaud the writers, staff and all involved in the making these drama. Thank you and sequels should be something to look forward to.

Nivin Jun 12 2026 5:25 pm Literally perfect a Mix of sadness of the reality of the world with some comedy in between, making you cryy because of this cruel story and laugh on small things. All the actors did a great job and a very convincing performance bravooo. Everyone should watch it fun with a Strong message. Honestly very good editing, music, colours, the choice of the actors and all the stories are insane and mind blowing, I cried of the idea that this is happening in our real world !! It makes it more killing. Strong series don’t stop making masterpieces like this !!

Buchay Jun 12 2026 1:52 pm The hand pose ? right before the slap is epic! Hoping for a season 2!

webtoon reader Jun 12 2026 12:37 pm Ya'll should read Get Schooled webtoon, that's the webtoon for this series. it has 240+ chapters, and each are soooo satisfying!!

Waiting for Gu Sera on this series soooon!!

Riri Jun 12 2026 10:00 am After Teach You A Lesson, I had to rewatch Hospital Playlist for a 3rd time coz there was nothing good and new to watch. Lo and behold, the annoying mom in TYAL who didn’t want her child to solve a problem on the board is in S1 E1 of Hosp Playlist.

kimhaewon Jun 12 2026 7:51 am There's bound to be a lot of comments asking for season 2.

Even though everyone here is watching illegally.

What a crap...

Gawon Jun 12 2026 5:00 am Season 2 pleaseeeee! This series truly deserves the top spot! I was completely hooked after the first 10 minutes. No boring episodes it reminds me of my Fav series Taxi Driver, PDnim please we badly need Season 2 for thisss amazing showww

N Jun 11 2026 6:08 pm Was this series filmed a year ago? Actor Song Young kyu appears in this series, but he passed away a year ago!

Kpocchaco Jun 11 2026 4:19 pm An absolute 10/10 masterpiece. If you loved 'Taxi Driver' but want something grittier and completely focused on the dark realities of the school system, 'Teach You a Lesson' is a must-watch. It handles incredibly heavy, realistic topics like intense university entrance stress, schoolyard extortion, drugs, and bullying with unmatched intensity. Each of the 10 episodes has a distinct, powerful feel, and the pacing is brilliant. The chemistry between the four main leads—Na Hwa-jin, Im Han-rim, Bong Geun-dae, and Minister Choi—is fantastic. Perfect balance of high-stakes action, social commentary, and a touch of grounded romance. Highly recommended!

JL Jun 11 2026 2:09 pm All i can say is, Season 2 Pleaseeeeeeeeeeeeee

Riri Jun 11 2026 11:37 am Dang this series! Whew! KIm MU-yelo is not only cool, but Wayyyyyy cool! Love the full circle milenya in thr last Episode. Listen and Learn. listen and learn! Chihuahua!!!

Ze Jun 11 2026 9:40 am Probably the best kdrama in 2026, the pace, the action & the comedy are spot on. Highly recommended

SiliconValley Jun 11 2026 3:50 am I am a teacher and I approve this drama!

Gio Jun 11 2026 2:59 am ex military + good at fighting + handsome.. sounds like someone i know in a taxi company xD cant help but thinking if theres a crossover between the 2, facing the big bad of all time. the budget gonna be huge but it will be worth it imo

Jade 1960 Jun 11 2026 12:42 am Amongst the best dramas so far. Probably the best and long overdue.

Definitely deserves best drama of the year.

I’m torn between this drama and we are all trying here, However these two dramas are exceptional, in a different league from the rest.

Can’t wait to find out the results.

Daesang to the lead actor in we are all trying here, Best actor to lead actor in teach you a lesson.

Best drama, teach you a lesson.

We’ll see:)

BN Jun 10 2026 6:53 pm Best drama of 2026.

One of the biggest challenges teachers face is parents... the kids they raise and the way they treat teachers when the teachers address the behaviors of the kids they raised. Having watched dramas with South Korean parents and their kids abusing teachers or teachers having no power to defend themselves against unjustified behaviors of students and the parents who raised them, this drama was soo cathartic. Hands down the best drama of 2026.

I love dramas like this and Taxi Driver (all 3 seasons). I hope to see more.

Jane Jun 09 2026 7:01 pm Hands down to the actors/actresses. This kdrama is just so cool and can really teach you a lesson. Thank you for showering us a good show, fighting!

Hala Jun 09 2026 6:00 pm We need season 2 teach you a lesson

Laura Jun 09 2026 5:34 pm Probably best kdrama I watched in 2026 so far. No boring episodes . Good acting with little comedy with much action . Unique amd really discussed about several topics which are hidden in education industry . Yp this is fiction and really not all bad kids are extreme specially those ep 2 fighters really got some sense they really didnt became criminals . Issues about teens who are manipulators,killers,bullies, drug lords, teacher harassers and teachers who abuse their power,parents who make teachers and child's life hell

Jess Jun 09 2026 2:43 pm The best drama ever I have watched. I’m sure this show gives some countries especially the U.S an idea to create an organization like the ERPB. Don’t you think? I bet.

This show deserves more than 5 stars!

Mira Jun 09 2026 12:34 pm Totally the best 2026 kdrama…there’s alot of bullying cases in Korea,things like that should be paid attention to!!!

Clk Jun 09 2026 9:54 am Best of the best! Good job!

Reese25 Jun 09 2026 9:42 am Kim moo yul, Lee sung min, Lee sang hee, Park ji yeon they were together in juvenile justice ?

Priscilla Remedios Jun 09 2026 6:58 am I really want thank the director who created such a brilliant topic about what really happens in schools and colleges.Right time to improve what was lost because of bad institutions of rules.Many talented teachers and brilliant students lost their life because of bad discipline and bad behavior and bullying. Cast of the Teach you a lesson brilliant choosen and very happy for them. Hope all school children and the teachers see this whoever harassed and done this is a time you realize and change. I too once was bullied so I know how it feels. Good Luck To All For Team Of Teach You A Lesson hope we get see more of it. Next hope the topic be on politics people because of their children rules the school just because they pay for the fund for school and college. I just want to say one thing be brave and and face the person directly dont give up and don't make your choice as suicide is the only option. There are many who like to help if only you ask for Help.

Yesil Jun 08 2026 11:09 pm Highly recommended! Every episode is exciting!!!

algorithms06 Jun 08 2026 6:16 pm I got soo emotional watching this. Everyone has such a sad story. The acting is also very good. One of my favorites in 2026.

Lina Jun 08 2026 12:35 pm What a great surprise this series turned out to be! I started watching it without many expectations and ended up completely hooked. The storyline was engaging from beginning to end, with the perfect mix of action, suspense, humor, and emotion. What I appreciated most was that it wasn't just entertaining—it also carried important messages and lessons that made the story feel meaningful. The characters were well developed, the performances were fantastic, and the dialogue felt natural and refreshing. There were so many moments that were oddly satisfying to watch, and every episode left me wanting more. It's rare to find a show that keeps you invested while also making you laugh and reflect at the same time. Definitely one of my favorite Netflix watches lately. Now I'm crossing my fingers for a Season 2 because this is a story I'd love to continue following.

Eri Jun 08 2026 10:42 am I hope there's a second season! There's so much to explore in the plot (I haven't read the manhwa), and my Geundae-Hanrim ship is just starting to sail. T_T

Lyd82 Jun 08 2026 10:40 am "Teach You a Lesson" is a highly engaging K-drama with a fantastic storyline and great writing. But, the actors playing the middle and high school students look visibly mature, appearing more like they are in their mid-twenties than actual teenagers.

Aeryn Jun 08 2026 7:49 am I've never gave any comments here but this drama is so good that I couldnt move on! Kim Moo-Yul really nailed this character! Probably will be my best kdrama of the year!!!

Kdrama_nerd Jun 08 2026 7:23 am Jo Hyun Woo (EP 7) is so immersed in his character. I actually felt so much and cried for a father character, for the first time. This also made me look into more of his other work. Big Fan

Lucy Jun 08 2026 7:06 am Wow!

Another great drama! It does feel like *TaxiDriver ????

G Jun 07 2026 7:58 pm U Jin’s mother is the scourge of the earth. Toxic parents like her should have their mental health evaluated before even being allowed to conceive. Mad woman.

Bimini Jun 07 2026 2:06 pm Impressive. Tackles a difficult subject matter from many perspectives. Well written and constructed script and story line. Presents one possible alternative way in which to handle each of these cases. Believable acting, with little build up to each scenario.

K-li Jun 07 2026 1:26 pm Does anybody knows who plays the soundtrack "Chihuahua" in the show?

shanks Jun 07 2026 8:46 am as a standalone it's decent but knowing the webtoon.. it's such a shame because I really did enjoy the webtoon in the beginning :(

Anna Jun 07 2026 7:47 am This drama is so amazing kinda giving Study group's vibe. I love it

Maria Jun 07 2026 7:31 am I love the series so much. I feel like I'm watching Taxi Driver meets Juvenile Justice. ?❤️

Riri Jun 07 2026 7:15 am This has the feel and vibe of Trauma Code where there is one main character who defies the norm and is supported by a slew of his or her loyalists. Somebody mentioned about John Cena. Now , I cannot unsee it.

Qweerty Jun 07 2026 4:01 am @Dimitra was right. @kcecece is the actress who plays Oh Yun-Jin

Virtusa Jun 07 2026 12:51 am Love the series!!! Hope it’s sequel to Brave Citizen movie and Hope Shin Hye-Sun would appear here. ???

Saranghae Jun 06 2026 4:31 pm I want to retract what I wrote below. I'm on episode 4 and only now I can say that the whole story makes sense. Great series.

someone Jun 06 2026 4:12 pm Kim moo yul is so atractive here?????. Btw this is my first time kim moo yul kdrama ?

Mr Jun 06 2026 3:04 pm This was surprisingly the best kdrama. I love this kind of drama. This is the reason I watch kdrama. There is message, moral and fighting against corruption and fighting for the victims.

dludiodioo Jun 06 2026 12:28 pm Oh.My.God The MC is literally look like the exact copy of the Manhwa. I'm so down for this. I hope it has 100 more episodes

AC Jun 06 2026 11:44 am The story is incredibly relatable and reflects today's reality remarkably well.

ac Jun 06 2026 11:42 am The story is incredibly relatable and reflects today's reality remarkably well.

Best Kdrama of 2026 Jun 06 2026 11:04 am This is one of the best Kdrama I've watched this year 2026. The topic was so heavy and heartbreaking and I always cried at the end of each episodes but still I enjoyed watching this series, it was perfectly blended with funny, action, great acting, heavy scenes and heartfelt scenes with this Kdrama. It deserves all the love, recognitions and awards soon in. Kdrama acting in Korea.

squi Jun 06 2026 7:44 am @Saranghae tbh, i don't even think this drama is exaggerated. Teachers are cowards. And this does happen in real life. There are alot of bullying cases in korea, especially with hierarchy involved, and even worse than this. Maybe you should do more research.

Saranghae Jun 06 2026 7:00 am What I think is that this drama is exaggerated and unreal. Where is this happening? Moreover, where are all the teachers????? Doesn't anyone see that in the classrooms and in the hallways of the school there are children being abused????? Come on, give me a break ?‍♀️?‍♀️?‍♀️

augmentedmelon Jun 06 2026 4:59 am now that we got study group and true education, we need a to not die drama (cast me as dajun please), also to not die the webtoon was shown in the gambling episode

maria.georgianne Jun 06 2026 1:32 am is it just me? i find hwa jin and han rim's chemistry sooooo??? please i'm hoping this will end with them

Jamse Jun 05 2026 10:21 pm Is it just me, or does Na Hwa Jin resemble actor and WWE star Jon Cena?

RM Jun 05 2026 6:57 pm 10/10 The whole ERPB team was aura farming especially na Hwa jin and Choi gang seok. Han rim and geun Dae were great too Spoiler

My only disappointment is that Hwa jin should've beaten up that gyu cheol even more in the climax than just the whole circle kind of emotional moment with forgiveness again. I would've crashed out if minister Choi hadn't come to gyu cheol and list out his crimes and saying he'll never step foot into the school again

gha Jun 05 2026 4:23 pm I really thought Kim Nam Gil was the main lead but when I watched Kim Moo Yul, she was super good. It's really like that, whoever is the second choice, the drama will really be a hit because she's good and the lead is great❤

F Jun 05 2026 12:23 pm Is Im Han-rim the daughter of the owner of Hanlim Gym? I read her story in manhwa.. she was the one who coaches the uncle of Yoon Ga-min to be a fighter. Does it mean that she's older than Ga-min's uncle? And Get Schooled/True Education comes first to Study Group? Please someone summarized the Blue String Universe? ?
