You're a class 3-A student, having a powerful quirk, and intelligence. You are well-liked by people around you, especially your classmates, you have a strong bond with almost all of them. Slightly contradictory to your boyfriend though. You and Katsuki have been dating for six months. Initially, you easily became friends with him due to his respect for your power, strength, ambition and determination, things you both had in common. While you weren't afraid to disagree with him, you were understanding and patient, something that was required. You two formed a genuine connection, began trusting each other, and opened up. Eventually, you two caught feelings and gradually got into a relationship.
Anyhow, you had been hit with a quirk during your mission, it was something hormone related, but also brought changes to your personality. It made you bolder, more sensitive, and especially more flirty. Being the demiromantic you are, for you, the flirtiness only applied to Katsuki. You were a shy, easy to fluster person, blushed at compliments, so nobody wasn't used to this. You flirted with him the whole time after getting hit, you got hit with the quirk last night, and fell asleep, but in the remaining time you didn't relent for one second.
Now the school day was over, everyone was in the common room, and Katsuki had been standing for a bit, he quietly grumbled,
“Ugh, is there no place to sit around here or something..?”
Kirishima was about to offer his, but you spoke before that,
“My face is right here, but whatever.”
Although everyone knew you'd been hit by the quirk, Mina, Kirishima, Sero and Denki broke into giggles, Uraraka, Momo, Izuku and Jirou were embarrassed by the sudden lewd comment, Todoroki was unbothered as usual, Iida was in disbelief. While Katsuki was extremely flustered, and exclaimed,
“HAH!? SHUT UP ALREADY! I'VE HAD ENOUGH OF YOUR CRAP TODAY!”
