Netflix's new viral K-drama Teach You A Lesson has arrived with some baggage. The K-Drama is based on a webtoon by the same name that has come under scrutiny for featuring violence, physical punishment, and racism within the classroom. Director Hong Jong-chan addressed this head-on, collaborating closely with the screenwriter to strip away those problematic elements and craft something more thoughtful and purposeful — and the result is one of the most compelling dramas of 2026 so far.

Storyline

The series is built around a fictional South Korean government body — the Educational Rights Protection Bureau (ERPB) — established under the Teacher Rights Protection Act in response to rising school violence and weakening administrative authority. Leading the charge is former Special Forces Captain Na Hwa-jin (Kim Mu-yeol), a sharp and physically formidable investigator. The entertaining Inspector Hanrim (Jin Ki-joo) and nerdy District Deputy Manager Geun-dae (Pyo Ji-hoon) assist him with their boss from the Ministry of Education, Chief Choi Gang-seok (Lee Sung-min), who is using his experience as a father to help find ways to address issues related to education. Each episode showcases a distinct instance of corruption or abuse that happens in a public school and has a similar format to a courtroom drama.

Positive Points

Every single actor involved in the production delivered superb performances over the course of the full series, which is exceptionally well written and paced. Kim Mu-yeol's performance is so intense and powerful, comparable to John Wick's, that it is surprising he hasn't yet starred in any major roles with Hollywood. Lee Sung-min's character is multi-faceted and brings emotional depth to his performance, while Jin Ki-joo's humorous performance steals all of the scenes he appears in. The series expertly balances between these two types of performances.

Negative Points

The series explores many significant social issues, including cyberbullying, parental pressures placed on children, and economic inequality; however, these serious issues are handled in a sensitive manner that presents these issues as necessary, real-life issues rather than merely opportunistic.

Overall: Teach You A Lesson is a smart, emotionally engaging drama that uses entertainment as a vehicle for meaningful social commentary. Despite minor missteps, it's a must-watch — and absolutely deserves more seasons.
