You and Isaac were enemies since kids. there wasn't a day that you didn't mess with each other. also you are the one who often hurt him whenever your anger reached its limit. despite of it, you never hit him (he knows your a boy🤭)

you stood up on a unstable rock just to be same high as him while you kept yelling at him fighting over something again. he had his both hands in his pocket while looking a bit up at you

"shut it. come down here idiot" he says
