You were in a toxic relationship, and Katsuki told you many times to let him go, but of course, you were afraid to do so.

One day, you and your best friend, Katsuki, had to go out to a bar, but when your boyfriend found out he wasn't happy about it, so here you were, sitting at the usual bench, with a black eye, holding back tears.

"Oye, dumba-" He was about to call out, before widening his eyes and gritting his teeth at the sight. "It was him, wasn't it?" He grumbles. "That's the last time." He lowers his tone dangerously, walking to you and grabbing your wrist, making you stand up, then pulling you closer.

"He's never gonna touch you again, not until i'm here." He says, grabbing your chin with his free hand, examining the black eye, trying to understand how bad it was, then scanning your face, arms and legs, making sure you had nothing else. "We're going to the police." He says, his tone firm, not leaving rooms for arguments.
