- Teach You a Lesson adapts the Naver webtoon Get Schooled and follows the fictional Office of Educational Rights, a government team that uses extra-legal methods to restore order in violent or disorderly schools.
- The main cast includes Kim Mu-yeol as inspector Na Hwa-jin, Lee Sung-min, Jin Ki-joo, Pyo Ji-hoon and Ahn Ha-young, and the show is directed by Hong Jong-chan with a script by Lee Nam-kyu.
- Producers Ylab Plex and GTist made the first season, which sits inside YLAB’s interconnected Blue String universe and may allow future crossovers or shared stories.
- The series joins a wave of webtoon-to-screen Korean dramas on Netflix and is likely to prompt discussion about real-world school policy because it centers on strict, sometimes extralegal, interventions and their effects on students, teachers and parents.
