Fight back, we’re here to know why and solved the root cause.
I felt bored and fed up from the beginning. I'm honestly tired of bullying-centered stories, especially when they keep reinforcing the idea that this is simply how the whole world works. In reality, isn’t like that. These narratives often normalize and perpetuate hierarchical mentality rather than challenge it.What I find most disturbing is how these dramas can indirectly influence young viewers who are still developing their sense of self-worth and identity.
Constantly portraying cruelty, power imbalances, and social dominance as unavoidable realities can leave a harmful impression, especially on those who are vulnerable to internalizing those messages, hah.
I don’t want a savior, I want to learn why I should save myself and that’s why I think I like this drama because the lead actor is implying that he’s ain’t here to be the savior but yourself and he’s here to guide you how you can.
About the females lead who’s a teacher. I am utterly disgusted who’s saying she’s too much involved, she’s ain’t. She’s being her, she’s being a teacher. Just like the kindergarten/elementary teacher. It’s part of Asia culture to care for their students deeply just like ‘bullying culture’ it is in the culture. They just showed the focused on the boy because they want you to sympathize with him. But, no. I will only said it twice. No, she literally does that to her all students, that moment is just highlighted. In Asia, teachers are literally the second parents, in their off time they visit students that didn’t attended the class and even provide for them. In my country Philippines currently it’s a part of job.

2Rage healing and glorious slaps.
Let’s start with the fact this drama is borderline fantasy. This is not a show you watch for realism. This is a show you watch for rage healing. Half of these teens would be dead or in coma after even one of these slaps delivered by one and only Na Hwa Jin. With that in mind, you just cannot take the delivery seriously, but at the same time, you can appreciate the serious and realistic themes presented.Teach You a Lesson is the purest form of entertainment. Gripping stories presenting many social issues that we all struggle with one way or another. Great heroes with fun and distinctive personalities. Complex dynamics between being victim and perpetrator and the moral dilemmas of rightful punishment and empathic help. Villains that are rage inducing enough it’s worth paying attention to their schemes, but not powerful enough to feel like the stakes are greater than life. Amazing fighting choreographies, great styling, soundtrack that makes your heart race and slaps that make your head spin. What more can anyone wish for?
This is by all means an easy binge watch type of a drama. While the bullies and abusers are awful, the way the stories are structured makes it easily digestible. No matter what, you know Na Hwa Jin will deliver his lessons and justice will be served. And the way he serves it is just magnificent. I have never seen better slaps in any drama ever. I am a strong believer that a good slap is better than a punch.
What’s more, I really like how balanced the characters were - cool Na Hwa Jin, professional Choi Gang Seok, crazy Im Han Rim and adorable Bong Geun Dae. Their personalities mixed and matched in all the right ways creating this unique and energetic synergy. While we had a rather meaningful and clear set up for Hwa Jin, Gong Seok and Han Rim and their involvement with ERPB, I wish we got the same clear answers for Bong Geun Dae. They hint what his background is, but it’s never as well stated as the others.
As a team they had their small conflicts and hiccups, certain disagreements on how to deal with presented situations and problems, but at the end of the day they always knew how to unite and work together.
For the cases, I’m not gonna sit here and pretend like they were well explored analysis of complex social issues, but I do appreciate how even with the simplicity they were able to highlight, even if just one the suffice, how complex these environments and dynamics between people are. Things like why do bullies bully? How much of them being prior victims should be considered when delivering punishment? Is resocialization always an option? Does everyone deserve a second chance? Do parents always want the best for their kids? Do kids bear sole responsibility for their actions? How much should the system be blamed for failing these kids? These are just a few examples of the themes tackled in the plot.
While Teach You a Lesson for sure highlights the bad deeds done by kids/teens and the lack of protection and authority teachers have, I do appreciate how we still got few examples of kids being the victims, teachers and parents being the abusers, and the system not protecting anyone - if the system does not protect the teachers, it does not protect the children either. If people who are supposed to educate and help raise these kids cannot do their job, at the end of the day it will mostly fail the students who will grow up into awful adults. Nothing was truly black and white (well, maybe some characters were closer to one or the other end of the spectrum), it was not all kids are evil and all teachers are poor victims. Everyone took part in upholding that failed system.
What I liked others can see as a flaw, so it’s worth pointing out. They don’t stay in one school for more than one episode. They are all one time close cases, there is not that much time for deeper exploration. This is not a character driven drama. The structure is simple, the set up is simple, the solutions are straightforward. But all that simplicity is just well crafted and delivered and that’s why it works.
On the actual flaws (though this is gonna sound bad), I hate how the female perpetrators did not get the same treatment as male. Ain’t no equality here - not one slap was delivered even if the girls were just as vicious as the guys. Especially since I heard it’s not the case in webtoon and there Im Han Rim does not hold back. It was especially evident with the set order of the episodes and the cases presented - one episode teen boys get their fingers broken, the other episode the girls get their collars grabbed and shoved a little bit.
For the more technical aspects - the performances were phenomenal. Shallow of me, I know, but Na Hwa Jin was extremely hot in this role. After every episode I kept thinking how attractive Kim Mu Yeol is in this role. Add actually amazing acting skills - that’s a whole package. Whenever empathy, ruthlessness, sadness, excitement, annoyance - no matter the emotions needed, he delivered. I don’t think I need to convince anyone that Lee Sung Min aced the role. I’m here just stating the obvious. Jin Ki Joo and P.O also shined in their own way - the roles they were playing were a bit less rooted in reality and extreme - nice contrast that worked well on screen. And then we have Lee Bong Joon - I am sorry, but I am going to question the goodness of any character he ever plays, this role had quite an impact.
Then we have production - I don’t think I have any complaints. The fighting scenes were perfect. That one cinematic experience in rain? I rewatched it a number of times. Not only was it exciting to watch, it was also shot in a truly aesthetic way. I also really like when dramas use light as a framing tool. The soundtrack? Perfectly matched to the scenes and emotional impact it’s supposed to have - “First And Last” being my favorite song for sure.
Overall, eye for an eye does not work in real life but damn it's healing to watch it in fiction. Na Hwa Jin literally treating the bullies and abusers 1:1 how they treated their victims was such a blast to witness. I was honestly having a huge grin on my face watching the episodes.

What lesson are they trying to teach?
I caved and watched Teach You A Lesson. Let me tell you: a student getting slapped around should be the least of your concerns about this kdrama.There are some serious WTF moments and the way some issues are dealt with are definitely laced with korean right wing ideology.
Spoilers ahead.
As usual, when talking about social issues from other countries, disclaimer: I am not Korean. Just an art curator studying asian cultures and histories to better understand the creative processes. I am not here to put my western POV into this story, just to point out some things I found interesting.
Yes, Teach You A Lesson is a fantasy-action kdrama about confronting severe school bullying and protecting victims when institutions fail. I will also say it puts in the table school violence and educational issues that are rarely dealt with in a proper way in South Korea.
First, you should approach it as part of the kdrama family of Weak Hero Class 1 and Study Group. Except here, it’s a government agency doing the dirty work and not students beating the lights out of each other. The power dynamics are not the same.
Second, some episodes are really well done. I liked the one about a primary teacher being harassed by an overly critical parent telling them how to treat their “precious” children. There’s been several reports primary teachers taking extreme desicions because of it and government remains inactive.
I also liked the episode dealing with a mother pressuring her son to get into one of SKY med schools. It shows how children are pushed to extremes (mentally, emotionally and physically) to the point of pill dependency and burn out before they are even in university.
There are other issues such as online game gambling, something that has become a problem for high school student and parents around the world. Also, wealthy parents paying teachers to get exams ahead of time to the detriment of middle class/poor families whose children work and excel on their own.
BTW, the kdrama treats all kind of addictions as a crime and uses prison as “rehabilitation” but never questions if there should be new legislation to deal with this crisis, nor offers any message about access to psychological treatment.
And sure, a few episodes are pure fantasy.
With that said, let’s move on to the episodes that made me rise by eyebrows: A teen influencer accuses her male teacher of sexual harassment that leads to his death. Spoiler, she lied. This my first red flag.
Teach You A Lesson ot once takes this girl’s accusation seriously and offhandedly writes it off as a bully acting out. Using THIS particular issue to make a point about “teachers right to protect themselves against kids” is wild.
This episode could have been a good opportunity to explore the complicated relationship between teachers and students in a hyper-mediated environment. How both are left to become victims due to lack of government legislation or the naturalisation of a culture of online shaming, doxxing and harassment. Some reports published lately could have been enough for a solid episode if Teach You A Lesson really wanted to lean into a more realist approach. But this is not that kind of kdrama and you should be aware of that when watching it.
There’s also a direct or underhanded commentary, depending on the story, about kids hierarchy according to social status and economic circumstances. As well as “broken families” being an excuse to dwell into crime, even when we see some of these rich kids are probably the worst of all.
There’s a lot of talking about violence when it comes to this kdrama but I don’t see anyone saying anything about corporal punishment becoming an issue in South Korea only in the 2000s. And it was only by 2021 that all corporal punishment of children was banned under South Korean law. This means that, until 5 years ago, physical punishment was widely accepted in families, schools, the military and the justice system. And it’s likely still very much a thing today (when people are not looking… or not). Just giving context for those following the discourse of Teach You A Lesson.
Now, the most WTF moment of them all (for me): a governmental office illegally holding in prison four juvenile delinquents (shaved heads and all), refusing their parents habeas corpus, and exposing them to hardened criminals for bullying and dealing drugs is perhaps a right winger’s wet dream.
The fact this comes in the coattails of Shinsegae Group’s Starbucks Tank Day campaign leaves me speechless. This episode is truly tone deaf or outright propaganda.
Teach You A Lesson’s production team had no way to know this “controversy” would happen weeks before the release of the kdrama. But it does give pause, to say the least, they everyone involved in this kdrama thought that practices usually seen during dictatorships or extreme right wing regimes was a proper resolution to the issue of juvenile delinquency. Characters are criminals or victims. There’s no middle ground.
I said at the beginning this kdrama belongs to a particular genre of kdrama but, unlike those, Teach You A Lesson seems to want to deliver a message about the education system. That’s why I think it’s a missed opportunity to point out the need for legislation and educational reforms.

A unique, if unrealistic, take on school bullying
On the one hand, this show is deeply satisfying if you enjoy watching bullies get a taste of their own medicine, especially when those bullies are snot-nosed kids who think they're above the law. It also addresses a wide range of issues that affect students, teachers, and parents alike, including students bullying fellow students, students not respecting their teachers, teachers favoring students with connections and rich parents over students from poor backgrounds, parents bullying teachers, and the enormous pressure students face from their parents to perform well academically.On the other hand, this show is also ridiculously over the top and not at all realistic. The ERPB itself is government overreach to an absurd degree, and I found it really hard to believe that, in South Korea of all places, where public scrutiny of celebrities and elected officials is almost suffocating, there was not an immediate outcry over adults physically assaulting literal children, no matter how much the children deserved it. Not to mention the invasion of privacy and constant surveillance by the ERPB. Honestly, as much as I liked the main characters individually, I was actually rooting for the opposition party to disband the ERPB entirely. There's also the fact that the Bureau was founded after the murder of a teacher at the hands of her student, yet somehow no one knew that Ga-Yun, the murdered teacher, was actually the daughter of the Minister of Education who founded the Bureau and the fiancee of the Bureau's lead investigator until well after the ERPB was established. Han-Rim and Geun-Dae both routinely going undercover as students makes for some funny scenes and I get that they both look young but COME ON, you're telling me none of the students ever suspected them of being narcs?? Do not even get me started on their "romance," the negative amount of romantic chemistry they had should be studied. Also, what the actual HELL did they do to my girl Jin Ki Joo with that haircut?? South Korea's obsession with bangs should also be studied, my god, they treat foreheads like the Victorians treated ankles.
The last two episodes center around the student who murdered Ga-Yun as the big bad who has set up an extensive drug ring that spans multiple schools and goes so far as to commit multiple murders to maintain said drug ring. And yes, murder is bad, and yes, kids are capable of committing horrific crimes, but like, he's literally in high school. His brain's not even fully developed. I'm not downplaying his actions but there's a reason juvenile offenders often get lighter sentences and that is because their brains are literally not fully developed yet and as a result, they don't always know the consequences of their actions. Again, I'm not downplaying the actions of the bullies in this show, but it does make it hard to really root for the good guys when you remember it's literally a group of grown ass adults beefing with a bunch of teenagers. There's another episode earlier in the show where a group of kids who are also dealing drugs get thrown in a juvenile detention facility and basically get the shit scared out of them by the other prisoners who are legit murderers, and frankly, it's hard to really view this as justice when you consider that there's a very real chance they will get murdered before they get released. Maybe this is just my American worldview showing, but juvenile detention is not really considered a rehabilitative success here when most juvenile delinquents just end up becoming adult delinquents and commit further crimes.
As someone who doesn't particularly enjoy school bullying dramas primarily because it's so frustrating to watch the adults sit by and do nothing, I initially felt like this show was a breath of fresh air. The first episode in particular is fast and fun and I loved seeing an adult actually stand up to the school bullies and bully them back. But as the show progresses, it becomes harder and harder to stomach some of the extreme lengths the ERPB goes to to deliver justice. I've seen a lot of people compare this show to Taxi Driver because they're similar stories about people using violence for a good cause. Unfortunately, vigilante justice can only actually be delivered by vigilantes, and the ERPB is not that, they're literally a government agency. And when the government does it, it feels less like vigilante justice and more like the beginnings of fascism. I'm sure this show has more appeal to its native audience, but as an American, it hit a little too close to home for me, and not in a good way. If this show came out in 2024, I might've been able to just enjoy it for what it is and not think too much about it. But in 2026, when the U.S. government is figuratively and literally waging war on its own citizens and weaponizing different government agencies to do so, it's a lot harder to watch this and feel like it's anything other than a particularly insidious form of propaganda.

I didn't like ML and FL. FL is so annoying and always talks by shouting stupidly. ML constantly has the same facial expression, just smiling. But he is so good looking.I wish his acting was good.Even the students' acting was better. I actually liked him, but I didn't like him here. Maybe the director is bad.It’s too overdone. And by overdone, I don't mean the fight scenes but the students and the events.It didn't feel like a high school drama to me(For example, the students and the state of the school in ep2 are very exaggerated) Every episode has the same vibe. Overall it's soulless, not funny, and boring.

teach you a lesson is basically taxi driver set in schools, and honestly, it was ridiculously entertaining. the case-of-the-week format kept things fast-paced, tackling everything from bullying and cybercrime to toxic parents and academic pressure, while still tying it back to the tragedy that started it all. it's definitely unrealistic and leans heavily into wish-fulfillment justice, but watching the erpb give bullies a taste of their own medicine was undeniably satisfying. the cast had great chemistry, making this a fun, cathartic watch even when its message occasionally became a little too heavy-handed.Was this review helpful to you?

# MyDramaList Review**Headline:** A Disastrous, Cringe-Inducing Power Fantasy That Robs the Real Victims of Their Voice
**Status:** Finished Watching
**Spoilers:** Yes
**Language:** English
### My Ratings
* **Overall:** 1.0 / 10
* **Story:** 1.0 / 10
* **Acting / Cast:** 1.0 / 10
* **Music:** 1.0 / 10
* **Rewatch Value:** 1.0 / 10
### The Review
I completely forced myself to finish all 10 episodes of this show, and it is hands-down one of the most frustrating, poorly conceived dramas I have ever watched. If you are looking for a meaningful story about school life, bullying, or systemic reform, stay far away. This show is nothing more than an edgy, unrealistic adult savior fantasy that completely misses the point of what makes school stories compelling.
#### The "Cringe Teacher" Problem
The absolute worst part of this entire show is the Educational Rights Protection Bureau (ERPB). Watching Na Hwa-jin, Im Han-rim, and Bong Geun-dae crash into these schools like some knock-off Special Forces superhero squad is pure, unadulterated **cringe**. The show tries so hard to make these adult teachers look cool, badass, and dark when they interfere in student bullying. Instead, it just looks ridiculous.
Every time Na Hwa-jin stands in a classroom smirking, delivering an edgy monologue before physically assaulting a minor, I rolled my eyes. It feels like it was written by an adult who has a bizarre, power-tripping revenge fantasy against teenagers. The adult characters are completely unlikable, overpowered caricatures who never face real stakes because the plot completely bends over backward to make them look right.
#### The Victim Should Have Been the Protagonist
This show completely robs the actual victims of their agency. **I desperately wanted the victim students to be the actual protagonists of this story.**
Instead of watching a traumatized student find their inner strength, learn to stand up for themselves, navigate the harsh realities of school social hierarchies, or grow as a human being, the narrative completely pushes them into the background. The victims are treated like helpless, pathetic props just to justify the ERPB coming in to throw punches. We don't get to see the kids overcome anything; we just watch a grown man with Special Forces training beat up a bunch of high schoolers. It’s lazy writing and completely unsatisfying.
#### A Trainwreck of Cartoonish Plotlines
Every single arc across this timeline is cartoonishly exaggerated to try and make you root for the ERPB's extreme methods:
* **The Politician’s Son & Cyber-Clout Influencer:** The villains are completely one-dimensional. A teenager running a school like a military dictator? A girl destroying lives entirely for internet fame without any real nuance? The show lacks any understanding of real human psychology.
* **The "Monster Parents" and Drug Conspiracy:** Shifting the blame to toxic parents and underground academic drug rings just felt like an over-stuffed mess. The escalation from simple school bullying to a massive, multi-million dollar juvenile mafia run by Assemblyman Hwang Gi-tae was utterly laughable.
* **The "Going Rogue" Finale:** Episode 10 was the final nail in the coffin. The government freezes the ERPB, so these grown adults decide to go completely rogue and launch an off-the-books assault on a student-run syndicate. It completely throws away any realism the show pretended to have left.
#### The Toxic "Philosophical" Core
The show tries to pass itself off as deep by claiming that "true education requires accountability" and that the Juvenile Act just breeds monsters. In reality, it’s just an excuse to glorify violence and state-sponsored fascism in schools.
The acting across the board was stiff and over-the-top, the music was generic and forgettable, and the rewatch value is absolute zero. This is a massive miss. Avoid it at all costs unless you want to watch adults have a massive power trip over fictional teenagers.

Better Than Expected
I started watching this drama on a whim and ended up loving it. It gave off the vibe of early 2020s kdramas, largely because the writer mixed comedy and drama so well. The highlights were the acting and chemistry of the main cast (the core four), the intriguing plot, and the ending.However, the story telling it self isn't flawless. There are a few minor issues, and some of the casting choices regarding the supporting and guest characters were questionable. Overall, it was an enjoyable watch from start to finish.
I'd recommend this drama to anyone who has been missing good justice dramas.

The Most Satisfying Slaps Ever
➥ WHY I STARTED THIS DRAMAI started this drama as soon as it dropped on Netflix, without doing my usual ritual of checking trailers, reviews, or ratings beforehand. All I knew was that I love larger-than-life stories that tackle socially relevant issues. Within minutes, I was hooked. The action sequences immediately grabbed my attention, & seeing four actors I absolutely adore - Kim Mu Yeol, Lee Sung Min, Jin Ki Joo, & PO - made the experience even better. Having loved many of their previous works, I was already invested.
While watching, I checked MDL & found the ratings and comments quite promising. Then I discovered that this drama exists in the same universe as "Study Group". My reaction was simple: "No wonder!" I absolutely loved that drama & had even mentioned in my review that any sequel, spin-off, or side story from that world would likely be just as enjoyable. Turns out, I was right. [My review for STUDY GROUP: https://mydramalist.com/profile/omo-omo-omo/review/426780]
➥ BRIEF DRAMA SUMMARY
This drama is built around a highly idealistic premise. A special unit is formed to protect victims - whether students, parents, or teachers - & ensure that the right to education, fairness, & happiness is not taken away by those in power. While the story begins with a personal incident, it gradually expands to tackle deeper social issues, particularly those affecting the education system.
Like "Study Group" & "Trauma Code: Heroes on Call", it presents a world where people are willing to fight back against corruption & injustice. As unrealistic as that may sound, that's exactly what makes stories like these so satisfying to watch.
➥ MY FAVORITE PARTS OF THIS DRAMA
In reality, corruption often runs too deep & those who try to challenge it are frequently silenced. So even when these dramas push the boundaries of realism, I can't help but cheer when justice is served & get emotional when victims finally get the victory they deserve. Maybe that's why dramas like "Teach You a Lesson", "Study Group", & "Trauma Code: Heroes on Call" resonate so strongly with me.
The acting, comedy, action, & emotional moments are all incredibly effective, elevated further by sharp direction, background score & strong cinematography. The four leads are impeccable - as expected. Whether making you laugh, inspiring admiration, or pulling at your heartstrings, they make every moment count. Even within the drama's larger-than-life setup, they deliver memorable performances.
I also appreciated the recurring focus on juvenile offenders & how often they commit crimes yet escape meaningful consequences. It reminded me of "Juvenile Justice", & a small part of me would have loved a crossover. Then again, having Lee Sung Min in both dramas is satisfying enough in its own way.
➥ SHOULD YOU WATCH IT
If you enjoy this genre of drama, this is an easy recommendation & a must-watch. It is highly entertaining, emotionally satisfying, & delivers exactly what it sets out to do. Even if you have not watched similar dramas, but want to try - do it give a go.
Just like "Study Group", I hope this series receives a sequel & expands further. From what I understand, the "Blue String" universe is quite vast, & even though I haven't read the source material, I would love to see more stories from this world brought to life.

One of My Unexpected Favorites!
Teach You a Lesson was honestly such a fun watch. I started it without expecting much but it ended up surprising me in a good way. I was honestly hooked front one point and then binged watched like crazy. The story keeps things interesting and all the main characters feel relatable enough that you actually care about what happens to them. They were probably the strongest part for me because they felt real and easy to get attached to.What I liked most was how balanced each moment was. Some scenes in the eps genuinely made me laugh(especially FL's swearing rap lmao) and a few had me really invested in the characters' growth.
The pacing was pretty good overall and I never felt bored while watching.
If you’re looking for something entertaining with likable characters and a meaningful message I’d definitely recommend giving it a try. I had a really good time watching it and would happily watch it again.
And also it's a 10 for me!

If Violence Isn't Solving the Problem, You're Not Applying Enough of It
Don't get me wrong, I love seeing bullies get what they deserve. The revenge in this show is genuinely satisfying, and that feeling of payback is exactly what draws you in. But let's call it what it is: in this series, violence solves everything. The unspoken rule is simple, if violence isn't solving the problem, you're just not using enough of it. The government-backed team beats, humiliates, and terrorizes abusive students and corrupt adults because the legal system keeps failing. Every episode proves that going all out with force saves the day. The finale tries to get deep with a moment of restraint, but after eight episodes of rewarded beatdowns, that feels empty. So yes, 'Teach You a Lesson' is cool, satisfying, and deeply wrong. Watch it for the guilty fun, but don't pretend it's anything other than a show where the answer to every problem is a fist, and the only mistake is not punching hard enough.Was this review helpful to you?
