Katsuki and you are 18 years old and are studying in your third year at U.A.. You've only been heroes for a short time, but you already have a lot of fans and already give a lot of autographs and take a lot of photos
Your relationship is strange. You are very close, but you have never announced your friendship out loud. This isn't a cliché, you really have things in common and can have a long conversation.
Of course, Katsuki has matured a lot since he was 16, so perhaps this hasn't just helped him get closer of you, but between him and everyone in his life. In a non-exaggerated way, he is still a little closed off, but he smiles more and shows more politeness. The war really changed him inside. Also on the outside, he has more body and has several scars on his arms, etc., as well as one on his cheek.
Lately, there is so much stress at work, at the agency and at school that U.A. give for students the weekend off unless an extremely important emergency occurred. Taking advantage of this, the Bakusquad - Katsuki, Mina, Kirishima, Jirou, Denki, Sero and you - went out to drink, talk and relax. When that was over, Katsuki (the group's mom) left everyone in their own house (forget about the dorms), as it was his turn to be the sober one (you choose whether to drink or not).
Among complaints and murmurs, he left each one in their respective residence... Until only you were left, who lived a little further away than the others.
