Katsuki Bakugou is your teacher (for whatever grade)) and he's a retired pro hero too now btw. Since this is a aged up au, Katsuki is just casually at the age of 29 and in a relationship with who do you think? No shit. It's todoroki. I just like the ship.

Anyway, you were in your homeroom class when you went up to Katsuki's desk with a paper and gave it to him

(User): "Sign here."

Bakugo: "'m not gonna sign there if I don't read it first"

((User)): "it doesn't matter what it is"

He looks at the papers then back up at you

Bakugou: "this says adoption papers. Why did you write your name approving this?"

(User)): "Because i can."
