From the director of Juvenile Justice and the writer of Daily Dose of Sunshine comes a Netflix drama about a government task force sent to fix a broken school system — and judging by the newly released stills, the ERPB means serious business.
What Is Teach You a Lesson About?
Teach You a Lesson is a sharp, cathartic series about the fictional Educational Rights Protection Bureau (ERPB), a government task force created to restore teachers’ authority in an era of unruly students, demanding parents, and struggling schools. The series is directed by Hong Jong Chan of Juvenile Justice and written by Lee Nam Kyu of Daily Dose of Sunshine
The pedigree alone is a massive green flag. Juvenile Justice was one of Netflix Korea’s most acclaimed social dramas, and Daily Dose of Sunshine was celebrated for its emotional sensitivity — the combination of these two creative voices promises something genuinely special.
The systemic challenges facing teachers in South Korea — from parental pressure to student rights debates — have been a growing national conversation. Learn more about the broader education culture on Wikipedia – Education in South Korea.
Meet the ERPB Team
The newly released stills show the hero group ERPB stepping in to fix a failing education system, building anticipation for their upcoming actions. soompi
Here’s who’s on the task force and what they bring to the table:
| Character | Actor | Role & Personality |
|---|---|---|
| Na Hwa Jin | Kim Moo Yeol | Former special forces inspector; blunt but always stands with victims |
| Choi Gang Seok | Lee Sung Min | Education minister who founded ERPB; the bureau’s steady, sharp center |
| Im Han Rim | Jin Ki Joo | Junior supervisor; bold personality hidden beneath a polished exterior |
| Bong Geun Dae | P.O | Genius data analyst officer; somewhat naïve but steadily growing |
Na Hwa Jin is always seen in a black suit and is expected to deliver decisive action against those threatening the school environment. Choi Gang Seok delivers sharp rebukes to those who oppose the bureau, stressing the importance of its existence. Im Han Rim surprises others with bold actions that contrast with her polished first impression. And Bong Geun Dae, with his strong data analysis skills, works steadily to grow within the bureau over time.
The Director’s Take
Director Hong Jong Chan shared: “I remember the scene where the ERPB team first operates as a complete unit. When the four characters’ distinct personalities came together, I found myself clapping on set.”
When a director is spontaneously applauding on set, you know the ensemble chemistry is something special. This is precisely the kind of team dynamic that makes workplace dramas so satisfying to watch — four very different people, one impossible mission.
