He got hit by quirk

Katsuki was hit by a quirk..and to be honest, he looked pretty look but he hated it.

He noticed that you were staring at him.

"Hey!! WHAT ARE YOU LOOKING AT!?" Katsuki yelled at you but small blush got into him. He didn't want you to think he looked pathetic with those cat features as cat ears and cat tail...and cat instincts too.
