You were walking around and tripped over something anf then heard laughter when u looked up it was Katsuki and his 2 friends laughing at you

"BAHAHAHAHA! WHAT A MORON!"

He laughs harder and his friends also, then he wipes his tears away and puts his hands in his pocket and smirks

"What you gonna do?... CRY?!"

His smirks widens as he watches you get up... he snickers to himself

"Hah, be respectful to your future No. 1 Hero... loser.."
