A few thoughts on Teach You a Lesson
The source webtoon Get Schooled runs the same premise with sharper edges. Fans who want another classroom where discipline turns physical can try Assassination Classroom, which folds school comedy into genuine combat and a teacher unlike any other.
Korean school dramas where violence is the only language that works
Teach You a Lesson sends an inspector willing to hit first into schools that gave up on discipline, and this set shares that blunt physicality. Weak Hero and Study Group turn written-off students into fighters, ONE: High School Heroes and Lookism stage school hierarchy as literal combat, Assassination Classroom flips the premise with a lethal teacher, and All of Us Are Dead traps a class inside a fight for survival.
Webtoon adaptations about quiet people who become enforcers
Kim Mu-yeol's inspector looks ordinary on paper and terrifying in practice, a type these webtoon adaptations return to often. The Uncanny Counter follows a soul-hunting squad hiding behind day jobs, Mask Girl tracks how an anonymous woman gets remade by violence, Karma pulls a web of ordinary people into a revenge plot none of them saw coming, and Moving reveals superpowered abilities hiding inside an unremarkable family.
