“Sometimes, saving a victim takes more than teaching. It takes the courage to stop those who choose to do harm.”
Some K-dramas tell stories of love. Others revolve around revenge, family, dreams worth chasing, or second chances. Then comes Teach You a Lesson (참교육), internationally known as True Education and based on the acclaimed webtoon Get Schooled, taking viewers down a completely different path. It is a difficult, uncompromising, and often shocking journey that forces audiences to confront one of the deepest wounds in modern society: school bullying.
The series refuses to approach the subject lightly. It doesn’t seek easy compromises or offer comforting moral lessons. Instead, it asks a question that is bound to divide viewers from beginning to end: How far should society be willing to go to protect a victim? That is the very essence of Netflix’s 2026 K-drama, directed by Hong Jong-chan, the filmmaker who had already earned widespread acclaim with Juvenile Justice, where he explored juvenile crime with remarkable honesty and emotional restraint. Once again, Hong chooses to examine the darkest side of Korean society, adapting one of the most controversial manhwa of recent years—written by Chae Yong-taek and illustrated by Han Ga-ram—into a gripping, provocative, and strikingly relevant television series.
The Korean title, 참교육 (Chamgyoyuk), literally translates to “True Education,” while Netflix has chosen Teach You a Lesson as the international title. In Italy, many fans refer to it as Lezioni Vere (“True Lessons”), an unofficial translation that captures the spirit of the story despite not being its official title. The series envisions a South Korea that feels alarmingly close to reality, where the educational system has gradually lost its ability to protect students. Teachers have been stripped of their authority, school administrators are more concerned with avoiding public scandals than addressing serious issues, and victims are too often left to suffer in silence.
Out of this institutional failure emerges an extreme solution: the Educational Rights Protection Bureau (ERPB), a special task force created to intervene in the most severe cases of school violence. ERPB inspectors are granted extraordinary powers. They can enter schools without warning, investigate ongoing cases, infiltrate student communities, gather evidence, and employ highly unconventional methods to stop those responsible for bullying. It is important to clarify one essential point: the ERPB does not actually exist. The agency is entirely fictional, created specifically for the original webtoon. In real life, South Korea has disciplinary committees, government agencies, social services, and police departments dedicated to protecting minors. However, no institution possesses powers comparable to those portrayed in the series. The ERPB serves as a provocative narrative device, inviting viewers to imagine what might happen if the State decided to fight violence with equally uncompromising measures.
This is precisely what gives the drama its extraordinary power.
Every episode tells a fictional story, yet none of the cases feels unrealistic. On the contrary, the writers draw inspiration from decades of real-life incidents involving physical assaults, extortion, cyberbullying, group violence, psychological abuse, intimidated teachers, and students forced into silence. Rather than recreating a single true story, each episode blends together numerous real-life events, creating narratives that feel disturbingly authentic. It is this delicate balance between fiction and reality that makes Teach You a Lesson so unsettling—and so impossible to ignore.
At the heart of the story is Na Hwa-jin, portrayed by Kim Moo-yul, arguably one of the most charismatic characters of the year. A former member of a highly specialized military unit, he is now the lead inspector of the Educational Rights Protection Bureau (ERPB). He is not the typical K-drama protagonist. He speaks very little, observes everything, and exudes an almost unsettling sense of calm. Every time he appears on screen, he commands authority and complete control. He has no interest in compromise and wastes no time with lengthy speeches: his only goal is to protect those who cannot defend themselves. Kim Moo-yul brings to life a tough, seemingly impenetrable character, yet one who is deeply driven by an unwavering sense of justice. Alongside him is one of Korea’s most respected actors, Lee Sung-min, who plays Choi Gang-seok, the Minister of Education and the visionary behind the creation of the ERPB. It is he who conceived this controversial initiative, convinced that when every institution fails, someone must have the courage to step in. More than a politician, his character embodies the moral conscience of the series, constantly torn between legality and effectiveness, giving rise to some of the most powerful and thought-provoking dialogues in the entire drama. Completing the team is Im Han-rim, portrayed by Jin Ki-joo, a former military officer who joins the ERPB. She is highly skilled, determined, and capable of handling any situation without ever losing her composure. Beneath her discipline, however, lies a deep compassion for the victims, making her one of the most emotionally compelling and well-rounded characters in the drama.
Completing the team is Bong Geun-dae, portrayed by Pyo Ji-hoon, better known to audiences as P.O. He serves as the agency’s deputy director and is the team’s true technology expert. Digital surveillance, evidence gathering, hacking, and undercover operations are his areas of expertise. His sense of humor manages to lighten certain moments without ever diminishing the drama’s narrative tension.
Hong Jong-chan’s direction also deserves special recognition. Following the success of Juvenile Justice, the director once again explores the responsibility of institutions toward young people. Once again, the true antagonist is not a single criminal, but an entire system that has failed to protect those who need to be heard the most.
The series is based on one of South Korea’s most controversial webtoons. Get Schooled, published on Naver Webtoon, captivated millions of readers thanks to its fearless approach to highly sensitive social issues. However, this very narrative style also sparked widespread controversy, ultimately leading to the temporary suspension of the webtoon after criticism surrounding several particularly contentious episodes. As a result, the television adaptation became one of the most anticipated and debated Korean productions of recent years.
The setting plays a crucial role in enhancing the drama’s realism. Most of the story unfolds throughout the metropolitan area of Seoul, inside schools, gymnasiums, hallways, government offices, and urban neighborhoods that faithfully portray everyday life in South Korea. There are no glamorous sets or postcard-perfect locations. Every environment is carefully designed to make viewers feel that everything happening on screen could just as easily take place in the school next door.
Yet what truly makes Teach You a Lesson remarkable is not merely its action sequences, physical confrontations, or relentless pacing. It is the courage to raise questions that television rarely dares to ask. Is it right to fight violence with more violence? How far should the State be allowed to intervene in students’ lives? At what point does justice cease to be justice and become an abuse of power?
The series offers no easy answers, and perhaps it never intends to. Instead, it invites viewers to reflect, episode after episode, on an issue that continues to affect thousands of young people—not only in South Korea, but across the world. Because behind every statistic lies a human face. Behind every act of bullying is someone who simply wants to be heard. And behind every seemingly quiet school hallway may be a story that no one has yet found the courage to tell. This is where Teach You a Lesson strikes its hardest blow. Not because it depicts violence, but because it reminds us how devastating indifference can be. It is a K-drama that entertains, moves, provokes discussion, and above all forces us to confront a reality that we too often choose to ignore. And perhaps that is the most important lesson the series has to offer.
The fact that Teach You a Lesson is based on a manhwa is far from a minor detail. In recent years, manhwa have become one of the primary sources of inspiration for some of the most successful K-dramas, giving rise to acclaimed productions such as Itaewon Class, Sweet Home, The Uncanny Counter, Moving, True Beauty, and Business Proposal.
But what exactly are manhwa?
The term manhwa (만화) refers to Korean comics, the South Korean equivalent of Japanese manga. Although they may appear similar at first glance, they have several distinctive characteristics. Unlike manga, which are traditionally printed in black and white and read from right to left, modern manhwa are primarily published digitally as webtoons. They are presented in full color and designed to be read vertically by scrolling on smartphones and tablets. This vertical format creates a far more cinematic reading experience, with framing, pacing, and cliffhangers carefully crafted to immerse readers in much the same way as a television series.
Today, South Korea is one of the world’s leading producers of webtoons. Platforms such as Naver Webtoon and Kakao Webtoon publish thousands of new chapters every week, reaching millions of readers worldwide. The international success of these works has encouraged Korean production companies and streaming platforms, including Netflix and Disney+, to adapt many of the most popular titles into television dramas, playing a major role in spreading Korean culture across the globe.
Teach You a Lesson is a perfect example of this phenomenon. The drama is adapted from the webtoon Get Schooled (참교육), written by Chae Yong-taek and illustrated by Han Ga-ram, originally published on Naver Webtoon. The series gained millions of readers thanks to its uncompromising storytelling and its bold decision to tackle highly sensitive issues such as school bullying, abuse of power, the erosion of teachers’ authority, and the responsibilities of public institutions. Because of the intensity of its subject matter and several scenes that were considered controversial, the manhwa also ignited heated public debate in South Korea, becoming one of the country’s most discussed comics in recent years.
The television adaptation preserves the provocative spirit of the original work, transforming the pages of the manhwa into an intense and realistic drama while retaining its central question: What happens when the very system that is supposed to protect students stops doing so? It is precisely this ability of manhwa to explore complex social issues through compelling storytelling that has made them one of the most important creative driving forces behind today’s K-drama industry.
