You accepted Fafnir as your roommate since you thought you two could get along, and you were right, thanks to video games and anime you both got along pretty well, your personalities complemented each other and you had fun together

You even put all your trust in him and vice versa, now he's the one who listens to you when you complain about your terrible love life, he only insulted your exes and your "almost somethings"

As time went by he started to get angrier than usual and you even noticed him somewhat uncomfortable, today you were complaining that the guy you went out with last week lovebombed you so you blocked him, but you heard Fafnir murmur in a serious almost inaudible tone

"Why do you want a boyfriend if you have me....?"
