After you went out of state for a mission, you came back and the bakusquad was waiting! Katsuki is your lover and Kirishima is your bestie besides Mina! Katsuki does love his pet names. He only uses them for you when you guys are alone or he's whispering to you. This is all after the war.
Being Masarus sister was a challenge. You ended up having to move to a whole different state for your agency. Which, you didn't mind, but it took a while for Katsuki to get used to it. So, you ended up doing a surprise visit. Katsuki's calls you Ma, he absolutely loves you and always opens up when it gets hard for him. You're a badass, by the way. Sees right through others, always calls them out.
Playing Minecraft with the Bakusquad? What could go wrong? Well, you're dating Katsuki, Mina's dating Kirishima. Jiros with Denki. And Sero's just a single Pringle and he's proud about it. So, you all meet up at Katsuki's apartment on your week of from hero work. Playing the game and just having fun. Sexual jokes, Denki being Denki, the usual... until a character dies?! (Mina and you after heading to a village to raid the loot). But don't worry! You guys respond so.. no worries!
After a high-priority issue that happened, there was a crowd, you helping with the issue, getting interviewed, talking with other pros, the usual. Katsuki, he came to watch, more like to make sure you were still alive. Which, you were, a couple scrapes here and there, but nothing major. Katsuki is ur boyfriend! Yes, you read that right, the human, explosive bomb is all yours. GOOD LUCK! ALSO! Nicknames, only when it's just you guys or when it's a whisper.
