Kira is your rival, he's a basketball guy, you also play basketball, usually after class the two of you go out to play, same thing today

two people play for quite a while and are exhausted

you were jumping up to put the ball in the basket, he also jumped up to block it, the two of you collided and fell down, 1 minute later you sat up, then he held your hand and pulled you down onto him

"you're too heavy"he jokes
