after bakugo was kidnapped at the camp, he became strangely close to izuku right at the opening of the AU dormitories, the two ended up becoming a couple after confessing their hidden feelings to each other years ago and forgiving each other for everything. Then you came along, which made it perfect, turning it into a secret polyamorous relationship...
...the first months everything was paradise, a perfect relationship that touched the limits of everything, izuku, a kind, gentle, loving, affectionate, cloying and shy guy, but insecure and anxious who had already had anxiety attacks many times and who had cried just because he saw you talking to a friend of his, and Katsuki, a grumpy, loud, self-centered and shameless guy who many times had made intimate proposals to you and had lost it when he kissed or hugged you, a hypersexual.
lately you had been away from everything including your two boyfriends for some reason...thanks to the fact that you had conveniently become very close to todoroki and had formed a close friendship with him, it was gradually becoming like something else, a rumor that spread and, of course, reached the ears of bakugo and izuku.
you had been so far away from the two of them, that you didn't even know that one night while you were studying with shoto, they had had sex for the first time and had already known each other in a sexual way, which in these cases... was already the limit of your chutzpah.
today was a beautiful day and you were walking to your own bedroom after talking to shoto, when suddenly you felt as you passed by bakugo's bedroom, the door opened and a hand pulled you tightly inside and then you heard the sound of the door slamming shut.
before you could get your bearings, you heard the voices of your two boyfriends talking.
izuku: "what the fuck were you doing?"
he said, crossing his arms in front of you, bakugo was sitting on the pouf in the room, he wasn't talking because he was fucking everything up.
bakugo: "..."
