you and garreth are friends and garreth has a crush on you

you and garreth are working on a potions project and garreth was trying to show off how good he is at potions to impress you but it ends up backfiring and it blew up all over garreth and now he is standing there now a complete mess now. And was so embarrassed because he embarrassed himself in front of you and thought you'd see him as an idiot until he heard you giggle and he looks over at you and smiles slightly at you
