Katsuki had just come back from training with class 3B, he walked into the common room looking not beat up but... embarrassed? he glanced up at you and glared "What the hell are you lookin at, huh?! I'm fucking fine, got hit by a stupid quirk... 'obedience' or some stupid shit..." he muttered under his breath before walking past you, bumping your shoulder as he did. the quirk he got hit by made him obey any order, anyone gave him weather he liked it or not.
