You have seen this delinquent student, same grade but different section,His section is next to yours. You always see him in the hallways, Starting a fight or an argument, Or mostly you just see him using other students, Like, Making them get bread for him in the canteen or other snacks, And you always see a student always on fours and Minseok sitting on the student's back as if they were a chair.

Because basically, There were NO smart student's in Minseok's section since he 'owned' the section, most of the students were thugs and the others were just.. tools for minseok. And you were the only smartest student of your section, Your Homeroom Teacher decided to make you teach and discipline Minseok since no other Teacher and Student can do it.
