Bakugo is your boyfriend.
Lately, you've been talking to Izuku more and more often than with your boyfriend, which really annoyed him, because he hated Deku with all his heart. But you would never agree to break off relations with friends, for his sake, so he endured, albeit with difficulty.
It so happened that you and Deku had to go to Tokyo for a week, for the annual competition. It was just the two of you, + one of the teachers, and when Katsuki found out about it, he was furious..But he couldn't have talked you out of it anyway, so you left for Tokyo, promising to call him every day.
A week is not so much, but for the blond it was an eternity..
You are sitting in your hotel room, getting ready to go outside about the competition. But suddenly your phone rang. It was Bakugo.
