A government agency whose inspectors are legally allowed to use physical force on school bullies sounds like pure wish-fulfillment, and that is precisely the nerve Teach You a Lesson presses for ten episodes. Netflix released the entire season on June 5, 2026, and the show — adapted from the combative Naver webtoon known in English as Get Schooled — arrives carrying the same argument that made its source material a lightning rod in Korea. Here is what it is, where to watch it, who is in it, and the debate worth knowing before you press play.
The premise, without spoilers
In the series, the South Korean government sets up an Educational Rights Protection Bureau with an unusual mandate: its inspectors may use physical force and psychological pressure to discipline delinquent students. Na Hwa-jin, a former Special Forces captain, becomes one of them, moving school to school to dismantle the hierarchies that violent students build and to clean up the administrative corruption that lets them thrive. Director Hong Jong-chan keeps the tone blunt and the confrontations physical — this is a school drama shot like an action series.
The Korean title, 참교육, literally means “true education,” but in everyday slang it has come to mean giving someone the hard lesson they have been asking for. That double meaning is the whole show in two words, and it taps a real and ongoing anxiety in Korea about declining teacher authority and how schools handle violence.
Where and how to watch
Teach You a Lesson is a Netflix original, so it is available wherever Netflix operates, with the usual subtitle and dub options. All ten episodes dropped at once on June 5, 2026, in a simultaneous global release, so it is built for a weekend binge rather than a weekly wait.
The cast
- Kim Mu-yeol as Na Hwa-jin — the ex-Special Forces captain turned bureau inspector at the center of the story.
- Lee Sung-min as Choi Gang-seok — the Minister of Education who founds the bureau.
- Jin Ki-joo as Im Han-rim — a former Special Forces sergeant who becomes an inspector alongside Na.
- Pyo Ji-hoon (P.O of Block B) as Bong Geun-dae — a civil servant assigned to the bureau.
It is a notably grounded ensemble for a premise this heightened. Lee Sung-min in particular brings the kind of institutional weight that keeps the bureau from reading as a cartoon, and casting two former-soldier leads signals where the show puts its emphasis.
From webtoon to screen
The series adapts Get Schooled (참교육), the long-running Naver webtoon written by Chae Yong-taek and drawn by Han Ga-ram. The comic built a large readership on a simple, repeatable engine: a seemingly untouchable bully or corrupt adult is set up across a few chapters, and then the protagonist delivers the comeuppance the system never would. That structure is catharsis by design, and it maps almost directly onto the show’s episode rhythm — each installment building toward a confrontation the audience has been primed to want.
The controversy you should know about
This is not a frictionless feel-good watch, and it is worth going in informed. The original webtoon drew significant backlash over its handling of race, including racial slurs and stereotypes and what critics described as “reverse racism.” On the adaptation itself, the Korean Teachers and Education Workers Union publicly called for it to be canceled, arguing that the premise glorifies corporal punishment — which is banned in South Korean schools.
That objection sits at the heart of the series. The same scenes that play as satisfying payback are, read another way, an endorsement of force as discipline. Whether the show genuinely interrogates that tension or simply rides the catharsis is the question every viewer will end up answering for themselves.
Is it for you?
If you want a fast, physical, righteous-anger story in the vein of Korea’s school-revenge wave, Teach You a Lesson delivers exactly that, with a stronger cast than the genre usually gets. If you are uneasy about a story that frames violence as the fix for violence, the show will not soften that for you, and the on-screen brutality makes it a poor fit for younger viewers. Either way, watch it knowing what it is arguing, not only what it is selling.
What to watch next
If the “justice against school violence” theme is what pulls you in, The Glory remains the genre’s benchmark on Netflix, trading this show’s vigilante action for slow-burn revenge. And if you came for the webtoon-to-screen pipeline itself, it is worth remembering that Korea’s comic shelf is now where a great deal of the next wave of dramas is being scouted — Get Schooled is one more data point in that shift.
The real test for Teach You a Lesson is not its fight choreography but whether it provokes abroad the same argument it set off at home. Stream it, and you will know within an episode or two which side of that argument you land on.
