What Is the Show About?
Teach You a Lesson is set in a fictional version of South Korea where school discipline has completely collapsed. Teachers have no power, influential parents shield students from consequences, and youth gangs effectively run school campuses. In response, the government establishes the Educational Rights Protection Bureau (ERPB), a fictional special task force authorized to intervene in the most severe cases of school violence and institutional abuse.
Leading the bureau is Na Hwa-jin (Kim Moo-yeol), a former Special Forces operative who takes direct action against both student perpetrators and connected criminal elements. He is joined by field agent Im Han-rim (Jin Ki-joo) and digital forensics expert Bong Geun-dae (Pyo Ji-hoon), with the unit operating under Education Minister Choi Kang-seok (Lee Sung-min).
The story centers on student Kim Hyung-joo, whose case exposes deeper systemic failures in the education system. Director Hong Jong-chan has clarified that the ERPB is entirely fictional and should not be interpreted as a real-world policy proposal.

Why Is Teach You a Lesson So Controversial?
The controversy did not start with the show. It started with the source material.
Teach You a Lesson adapts the popular Naver webtoon Get Schooled, written by Yong Taek Chae and illustrated by Garam Han. The webtoon built a large following for its stylized action and sharp social commentary, however, it consistently pushed boundaries in ways that eventually caught up with it.
The breaking point came in 2023, when the webtoon’s 125th chapter drew intense international backlash. The chapter, which explored themes involving a Korean-American teacher and a mixed-race student, faced widespread accusations of racial stereotyping and harmful characterization. Critics pointed to offensive portrayals of multicultural communities, exaggerated character designs, and the use of racial slurs.
The response was swift. WEBTOON removed Get Schooled from its North American platform entirely and issued a public apology. The Korean version was placed on indefinite hiatus. The creators also apologized, acknowledging that while the intent was to highlight discrimination faced by multicultural families in South Korea, the execution caused genuine harm.
Beyond the racial controversy, the webtoon had also drawn ongoing criticism for:
- Mocking feminist viewpoints and social movements
- Depicting physical punishment of students as a justified solution
- Presenting authority figures using violence as acceptable discipline
- One-dimensional portrayals of secondary characters due to its episodic school-hopping format
Korean teachers’ organizations publicly called for a boycott of the Netflix adaptation, arguing that the series could glorify school violence and present unrealistic approaches to genuine classroom struggles.
Why Did Kim Nam-gil Turn Down the Lead Role?
When the Netflix adaptation was announced, actor Kim Nam-gil (known for The Fiery Priest) was first offered the lead role of Na Hwa-jin. The casting rumor immediately triggered significant fan backlash, with many urging him to decline due to the webtoon’s past controversies.
In November 2024, Kim Nam-gil addressed the situation publicly on social media, confirming his agency had received the offer. He stated that he needed personal time to review the decision, but at that point had no energy to focus on anything other than The Fiery Priest. Later, at a press conference for The Fiery Priest 2, he explained his position more directly, saying that if audiences were uncomfortable with a project, declining such roles was the responsible choice.
Why Did Kim Moo-yeol Accept the Role?
Following Kim Nam-gil’s exit, Kim Moo-yeol stepped in as Na Hwa-jin. At the June 5 production presentation, he addressed the casting controversy directly. He cited his previous collaboration with director Hong Jong-chan on Juvenile Justice, a series that also tackled difficult and sensitive social issues, as the reason for his trust in the project.
He said he hoped viewers would judge the final work on its own merits and evaluate his performance through the series itself, adding that actors ultimately communicate through their projects.
Clips of his performance went viral on social media following the premiere, generating significant online discussion.
How Did the Production Team Approach the Adaptation?
Director Hong Jong-chan, who previously directed the acclaimed legal drama Juvenile Justice, acknowledged the controversies surrounding the source material and spoke openly about the changes made during production.
According to Hong, the team deliberately removed the webtoon’s most divisive elements and approached the adaptation with extreme caution. He described the core appeal of the project as the fantasy of an organization that stands beside victims and supports them, rather than the controversial framing of the original work.
Netflix Senior Director Bae Jong-byeong also addressed concerns ahead of release, stating that the team was fully aware of the criticism surrounding the webtoon and had worked to approach the story with a more responsible and refined perspective.
Hong added that the series was inspired by real-world reports of school violence and aimed to spark reflection rather than provide simple answers, drawing on his own observations of school life through his children.
How Did It Perform Before Release?
Despite the controversy, Teach You a Lesson topped pre-release audience interest rankings. According to a May 2026 OTT content survey by Consumer Insight, the series ranked No. 1 in viewing intent at 10%, significantly ahead of competing titles such as Genie TV’s Doctor Seom Boy, which registered 3%. The combination of controversy and genuine audience curiosity proved to be a powerful draw ahead of the June 5 premiere.
