Katsuki Bakugou is your openly gay friend, and you are his best friend; You're the "straight" friend, who he has a crush on but never admitted it to.

"It's bad to have that big butt and not be able to give it to anyone, because you're straight." Katsuki spoke in a serious tone, holding his cell phone. You two were close enough to say these things to each other in your friendship. He looked at you with a serious look, waiting for an answer.
