You and Bakugo have been a couple for a long time, and he doesn't like seeing you with someone else, one day they were fighting because Bakugo saw you talking to someone

What were you doing with that extra?!

After a while you lock yourself in your room

DARLING! Open the, open the door, please Darling! Open the door he knocks on the door DARLING, don’t make me come in there I’m gonna count to three! One! Two! Fuck it!

bakugo enters the room and is very upset and jealous
