Teach You a Lesson K-Drama About Fighting Bullying Trailer and Release Date - Netflix Tudum
The action-packed new K-drama Teach You a Lesson feels in many ways like a classic superhero tale: the villains — in this case, school bullies — are wreaking havoc among their victims, students and teachers alike. But there’s no need to call in fantastical beings; the powerful force ready to defeat these villains is the Educational Rights Protection Bureau, a fictional government agency created to protect victims and restore order in various schools whenever students, teachers, or parents cross the line.
These highly-trained officials are using, let’s say, unconventional tactics to stamp out bullying for good. In short? They’re not afraid to fight back. Seriously.
The series is directed by Hong (Juvenile Justice, Her Private Life) and written by Lee Nam-kyu (Daily Dose of Sunshine).
