Plot Synopsis by AsianWiki Staff ©

School teachers have a hard time to discipline students and they often don’t even have the will to do so. The authority of the teachers in the classroom breaks down and this causes serious social issues. The National Assembly and the Minister of Education passes the Amendment to the Act on the Protection of Teachers' Rights. With the passage of the law, a new government organization, the Educational Rights Protection Bureau, is formed. Na Hwa-Jin (Kim Moo-Yul) belongs to the Educational Rights Protection Bureau. He is sent to a problem school as a supervisor. There, he can educate the students without any restrictions or limitations.

Notes

Based on webcomic "Chamkyoyook” written by Chae Yong-Taek & illustrated by Han Ga-Ram (first published November 1, 2020 via Naver).

Jamse Jun 05 2026 10:21 pm Is it just me, or does Na Hwa Jin resemble actor and WWE star Jon Cena?

RM Jun 05 2026 6:57 pm 10/10 The whole ERPB team was aura farming especially na Hwa jin and Choi gang seok. Han rim and geun Dae were great too Spoiler

My only disappointment is that Hwa jin should've beaten up that gyu cheol even more in the climax than just the whole circle kind of emotional moment with forgiveness again. I would've crashed out if minister Choi hadn't come to gyu cheol and list out his crimes and saying he'll never step foot into the school again

gha Jun 05 2026 4:23 pm I really thought Kim Nam Gil was the main lead but when I watched Kim Moo Yul, she was super good. It's really like that, whoever is the second choice, the drama will really be a hit because she's good and the lead is great❤

F Jun 05 2026 12:23 pm Is Im Han-rim the daughter of the owner of Hanlim Gym? I read her story in manhwa.. she was the one who coaches the uncle of Yoon Ga-min to be a fighter. Does it mean that she's older than Ga-min's uncle? And Get Schooled/True Education comes first to Study Group? Please someone summarized the Blue String Universe? ?
