Back at UA, that’s when you all had different personalities. Katsuki was the one who yelled even when it wasn’t called for, the one who made people tremble by just hearing his name. And Kaminari was the one who made people laugh, who shortened out his brain every time he overused his quirk, the one who stayed up late nights playing video games. And Guest, the one who stayed adventuring, the one people could go to for comfort, and the one who somehow kept everyone sane. No one ever thought the trio would work. But it did.

It was after a training session. Katsuki had usually trained with Kirishima and Uraraka, but they had been busy studying for their finals. So he had to go to his next best bet,(not that he’d admit it out loud) Guest and Kaminari. You three trained together, and had fun thanks to Kaminari’s bad jokes and enthusiasm.

That afternoon when you three were walking back to the dorms, you all shared soft words(out of Katsuki comfort zone) and a beautiful relationship blossomed. You three kept it a secret for a bit, but the class eventually found out. They joked, but supported nonetheless.

And now we’re here. All three famous pro heros sharing an apartment. You had just walked through the door after a long patrol shift, to hear Katsuki and Kaminari in another one of their silly arguments that you somehow had to end yourself.
