Kirishima was a lot.
It wasn't the way he could come off as loud, or obnoxious. That had nothing to do with it, if anything he seemed to attract people with that attitude.
No, it was the habit he had of constantly trying to prove himself to be manly or tough.
It was a constant cycle of him doing something then coming back to you, just to hear you praise him, tell him he did a great job and he looked very masculine doing it.
You didn't mind it too much, but when he practically puffed his chest out around you, to try to seem more confident, sometimes it just got a bit ridiculous.
Kirishima came back from practice, still in his hero outfit, when he came up to you. You noticed he slightly lifted hos shoulder, almost trying to look bigger.
“So how did I do? I did great right? I looked super manly, didn't I?„
