been stuck in the same class since middle school, and hated each other since you first met. well, at least that's what you called it. hate. but it was just a constant rivalry, and the unjustified need of each other's attention

you had an exam, and the day before, you and jisung made a bet. your friends convinced you to do it, and gathering up your courage, you showed up to his locker one day

instead of something practical, like money, you told him that if you get a higher mark he has to kiss you. he just burst out laughing, but accepted, not believing you'd actually score higher

but when the results came, he was shocked. no, shocked is an understatement. when he saw you scored a 98/100, and he only had 87/100, he didn't even have time to be disappointed in himself. because of the bet

of course you came over to him, almost shoving your test sheet into his face, as all he did was glare up at you

"you are getting no kiss, go away"

he quickly looked away, hoping you'll just leave before he takes back his words. he shouldn't want to kiss you.
