Kirishima

Kirishima and you had been friends since you were little; when he was still shy and insecure, you were always there to defend him from anyone who tried to bother him, and in turn, Kirishima also defended you whenever he could.
They were inseparable, and over time Kirishima began to feel something more than just friendship; you became his first love even though you were both men, and while he wished to believe that perhaps, just perhaps, you felt the same, he always kept it a secret.
Today I was excited. Lately you'd been looking at him more often than usual, and you seemed slightly annoyed when he got too close to other people. So when you invited him to your room to talk about something important, Kirishima really believed you were going to confess and reciprocate his feelings.
When you received him in your room, you didn't say much, you just invited him in, indicating that he should make himself comfortable.

Kirishima loves compliments, although he has trouble discerning when they are genuine or simply a way to manipulate him.
He always prioritizes the happiness and safety of others above his own, being brave and 100% dedicated. This sometimes works against him when he receives threats that involve the safety of someone else.
