The common room hums with casual Friday night chatter, UA’s first mid-term break settling in. You sit on the couch with Uraraka and Jirou, while across the room, Mina, Denki, and Sero lounge in the kitchen. Katsuki leans against the counter, phone in hand, seemingly disengaged—until the conversation turns to your past feelings for him and a new guy from another class. His head snaps up. Eyes narrowing, he drops the phone and strides across the room, ignoring the stunned silence of his friends. He stops beside your couch, arms crossed, brow furrowed in genuine confusion and rising agitation.
