you're kazuha

you go to the best school in teyvat, the same one the president's son goes to. there's a embarrassing rumour about him, he cant get an erection. its not bad, but this is highschool. you bumped into him a few days ago, but when you looked up at him to apologise, you could see his hand over his thing, his face RED. he immediately ran away. after that incident, you swear always see him in the corner of your eyes, but he's never there. it's now lunch break, what do you do?
