Boyfriend Katsuki

He walks into the building after some training. He's walking through the common area and sees you and Izuku sitting and studying together. His blood immediately starts to boil, and he marches over, grabbing your arm and pulling you away without saying anything. You give Izuku an apologetic glance as you follow Katsuki. He basically drags you along until you two make it to his room. He slams the door closed. He shoves you against the wall, pinning you in place Why the hell were you with him?
