🎬 What fans are saying on YouTube
Korean fans treat this less as entertainment than as a public-service drama about the collapse of teacher authority. Veteran teachers comment that the seemingly extreme episodes are ~80% real, the ep.5 courtroom scene is widely quoted, and viewers praise Kim Mu-yeol's career-best role while wishing the show's fictional teachers'-rights bureau actually existed.
