“Let us protect you!”
An inspector from the Educational Rights Protection Bureau (ERPB) who is authorized by the government to use physical intervention and unconventional methods to discipline delinquent students and reform the educational system.
Latest episode: S1 E10 Episode 10 (Jun 5, 2026)
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 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.
I didn’t expect to cheer for a man who slams a teenager’s head into a locker. But by the third episode of Teach You a Lesson, I was doing exactly that—leaning forward on my couch, pulse quickening, a guilty grin spreading across my face. There’s something intoxicating about watching a system that has failed so many finally deliver consequences, even if those consequences arrive in the form of a black-suited inspector’s knuckles.
The show knows this. It wants you to feel the thrill of justice served hot, then spend the rest of the hour questioning whether you should.
Hong Jong-chan’s series is a revenge fantasy dressed in the crisp uniform of a procedural, but its real subject isn’t bullying—it’s power. Who has it, who abuses it, and what happens when the people meant to protect you are the ones holding the knife. The Educational Rights Protection Bureau (ERPB) isn’t just a fictional agency; it’s a wish-fulfillment machine, a corrective to years of headlines about teachers too afraid to intervene, parents too entitled to care, and students too broken to hope.
Na Hwa-jin (Kim Moo-yul), the bureau’s enforcer, isn’t a hero. He’s a man with a badge and a grudge, and the show’s most unsettling trick is making you root for him anyway.
The first case sets the tone. A high schooler, bruised and shaking, confesses to being extorted by a gang of classmates who’ve turned his life into a living hell. The school’s response?
A slap on the wrist and a warning not to “escalate.” Enter Hwa-jin, who doesn’t just escalate—he detonates. In a sequence that’s equal parts John Wick and Stand and Deliver, he corners the ringleader in an empty classroom, flips a desk with a single shove, and delivers a monologue that’s less speech and more sermon. “You think rules are for other people,” he says, voice low, almost gentle.
Then he breaks the kid’s nose. Not with a punch—with a textbook. The camera lingers on the blood spatter, the way the boy’s body crumples.
"A brutally satisfying school-bullying revenge saga that pairs explosive action with charged social commentary, even when its morality and romance get messy."
The show lands as a hugely cathartic revenge drama, with each episode dismantling a new school hellscape and serving swift punishment to bullies, entitled rich kids, and complicit adults. Kim Moo-yul and Lee Sung-min are widely praised for anchoring the chaos, and the episodic cases keep tension high across diverse forms of abuse, from physical assault to cyberbullying. Graphic violence, a divisive stance on punishment, latestnetflix.com contends, and a tacked-on romance subplot leave some feeling conflicted or frustrated even as they binge through the whole season.
Gyeonggi education superintendent Ahn Min-seok watched all 10 episodes of Teach You a Lesson, then posted that the violence unnerved him and the school crisis did not. He called for a public debate on a real teachers' rights protection office. The limited series, adapted from the Naver webtoon Get Schooled, latestnetflix.com maintains, dropped worldwide on June 5, 2026. In its first three days it logged more than 6.4 million views and sat at No. 1 on Netflix's global non-English TV chart.

That is a messy win for a title that arrived with a protest already booked. In 2023, Webtoon's English site pulled Get Schooled after a chapter drew accusations of racist caricature. Korean teachers' groups had a different fight. On May 20, 2025, the Korean Teachers and Education Workers Union issued a statement titled "Violence Is Not True Education" and asked Netflix to halt the live-action. The union said a government inspector who assaults students in the name of protecting teachers would treat corporal punishment as policy. Civic education groups later held a press conference outside Netflix Korea in Seoul. ,
Netflix shot it anyway. Director Hong Jong-chan brought back Kim Moo-yul and Lee Sung-min, his Juvenile Justice pair, as inspector Na Hwa-jin and education minister Choi Gang-seok. Jin Ki-joo and Pyo Ji-hoon complete the Educational Rights Protection Bureau, the fictional squad licensed to use force in collapsing classrooms. Principal photography began in the first half of 2025. Netflix's own mission line is blunt. "We are not on the teachers' side or the students' side. We are on the victims' side." The trailer is car chases, hallway brawls, and that slogan sold as public service. , ,
Classroom groups split on the aftertaste. The Korean Federation of Teachers' Associations said it shared the show's sense of urgency, then drew a line. What teachers need, the federation said, is "not fists, but legal safeguards." A sixth-grade teacher in Jeonju told The Korea Herald that the malicious parent complaints and false abuse reports looked like the classroom next door. Student-rights advocates repeated an older warning. Physical punishment teaches the weak that violence is allowed. Parent organizers accused the series of turning school conflict into a criminal case. July 2026 reports of a second season remain reports. No filming dates, no locked cast. The policy argument did not wait. ,
