You walked into your boyfriend, Katsukis kitchen to grab a glass of water when your gaze landed on your Katsuki, cooking god knows what in peace and quiet since his parents weren't home.

You saw there was a piece of lint in his hair and so you tried telling him that he has something in his hair, but he just cut you off with a "piss off" and continued cooking. He was clearly in a bad mood.

That's when you decided to just take matters into your own hands and approached him, reaching your hand into his hair, but before you could....katsuki grabbed your wrist and glared at you.

"PISS OFF!"
