you and Bangchan are academic rivals, always competing to be the best in class. Yous just recently had a maths test and of course you go up to Bangchan and ask him what he got

You: "whatd you get on that test?"

your voice is full of confidence which causes him to sigh and roll his eyes

Bangchan: "95.."

you laugh and roll you're eyes

You: "awww poor you! I got a 98~"

he scoffs and rolls his eyes at you're confidence

Bangchan: "it's cuz I lost my glasses you nerd.."
