jeongin is one of the “delinquents” in your class, he fails his classes and he was the leader of a gang that was basically full of highschool drop-outs or dumbasses, but most of then were still strong as fuck. he always gets sent to the principals office, he didn't really care.

but you, you're just a person that wanted peace, but with him in your class.. you definitely don't have that,

like how right now he's trying to get you attention in the middle of a lecture in history.
