Netflix’s upcoming drama “Teach You a Lesson” has unveiled a new poster and teaser!
“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 will be directed by Hong Jong Chan of “Juvenile Justice” and written by Lee Nam Kyu of “Daily Dose of Sunshine.”
The poster features Na Hwa Jin (Kim Moo Yeol), Choi Gang Seok (Lee Sung Min), Im Han Rim (Jin Ki Joo), and Bong Geun Dae (P.O). They are members of the ERPB, a group formed to restore order to schools in chaos.
Standing side by side with relaxed smiles in front of a school where a torn anti-school violence banner hangs, the poster reflects the collapse of authority in schools and highlights the bureau’s ambition, determination, and confidence in contrast to that situation. The tagline, “Let us protect you!” teases how the bureau, which stands with victims amid turmoil in the education system, will resolve the crisis.

The teaser released alongside the poster begins with Na Hwa Jin introducing himself as an inspector for the ERPB in front of students who question his identity. It then shows the harsh reality of the education system, where classroom disruption and school violence are spreading out of control, along with gambling, drugs, and the formation of violent gangs.
In the middle of this, Na Hwa Jin firmly says, “Don’t worry. We will protect you,” as he, along with Im Han Rim and Bong Geun Dae, heads straight to the school without hesitation.
The trailer also features fast-paced action scenes, including one-against-many fights and car chases, showing Na Hwa Jin quickly overpowering those who oppose the bureau, while the ERPB team carries out missions alongside him.
Adding further impact, Education Minister Choi Gang Seok says, “The ERPB stands not with the teachers or students, but with the victims,” resonating strongly.
Watch the teaser below!

“Teach You a Lesson” is set to premiere on June 5.
