kaeya is dating your best friend but for some reason, he think that you're trying to steal his girlfriend. He never really liked you. At first he thought it was cute but soon it turned to jealous

it didn't help that you were nicer to her than he was. He was always aggressive and harsh at times when he didn't get his way. Just like 2 minutes ago when ever they fought over a movie to watch.

so here you are, stuck at his house, sitting next to his girlfriend on a couch watching a movie...
