Teach You a Lesson

Teach You a Lesson (Korean: 참교육) is a 2026 South Korean action school drama television series written by Lee Nam-kyu, Kim Da-hee, and Moon Jong-ho, directed by Hong Jong-chan, and starring Kim Mu-yeol, Lee Sung-min, Jin Ki-joo, and Pyo Ji-hoon. Based on the Naver webtoon Get Schooled by Chae Yong-taek and Han Ga-ram, the series follows 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. It was released on Netflix on June 5, 2026. The series achieved commercial success and generated strong domestic attention in South Korea, where it ranked highly across multiple buzz and popularity metrics, despite controversy surrounding the original webtoon. Critical reception was generally positive, with most reviews being favorable. In July 2026, it was reported that a second season was under discussion, with production details such as filming schedule and cast yet to be finalized. The show topped Netflix's global non-English television chart following its release, which was cited as a factor supporting the potential renewal.
