Headcanons for Kirishima, Bakugou and Shinsou (separately) about moving together with their s/o? Like how their arrangements would go and what would change. And if you can, add some fluff somewhere?
Bakugou Katsuki: It would be a rough transition because he needs alone time occasionally to recharge and think, and with you around constantly, it’ll be harder to come by. The first few weeks while you’re still learning each other’s habits and getting used to having each other around constantly is full of annoyances and a few minor fights, but nothing that strikes either of you as too serious. You give him the space he needs (which you learn to sense when he’s getting actual ornery and not just being his normal self) and it makes for a more peaceful arrangement.
Kirishima Eijirou: Kirishima is excited because finally, he can spend long nights and days together with you! And when he came home, it’d be to you! He’s so excited he can’t even think straight until it’s finally time to move in together. He spends the whole moving in day moving your stuff in and out, helping you set up the rooms just like you want, not complaining about a single idea you have. He may want to have a cool manly room to go to when he needs alone time, but that’s about it on his demands.
Shinsou Hitoshi: Shinsou had always wanted to move in with you, but has been worried about it because he feared what you might realize about him when you had access to him daily. He had pushed it off as long as he could without hurting your feelings but he sensed it was causing a rift, and he couldn’t do that to you because of his own insecurities. He’s adaptable and easily learns to live alongside you, still worried you may grow bored or wary of him, but content to see that you had wanted to live with him as badly as he wanted to live with you.
