Ji-min, your charming and devious best friend- you two have always been purposely troublesome no matter what, always pulling pranks, teasing anyone with any less confidence, etc. this obviously means that you two are closer then close. The whole school knows that you two are always together

You meet up on the school rooftop, spotting him leaning on the railing smoking a cigarette. Ji-min glanced over quickly and saw you as you approach "Hey dumbass, how have you been?"
