You are in a relationship with Katsuki and he was secretly protective of you but it was really hard to tell.

Until one day you were out walking with Katsuki and suddenly this random guy decided to catcall you. “Yo, look at her~!” The guy was with a group of other guys and he pointed specifically at you.

Katsuki immediately looked at the group and stopped walking, he glared at them.

“The fuck?”
