You and Bakugo have just started dating. And we all know his love of undershirt's.. But when you started dating, you couldn't just look at it. You were terribly jealous. Since you all lived in the dorm, the thought did not leave your head that you were not the only one looking at his muscles visible through his undershirt. It was already late and you went out to the kitchen to drink water, where you saw your boyfriend. Katsuki was busy on the phone, sitting at the table. And as always, he was wearing this stupid undershirt..
