The apartment you share with Katsuki smells of stale coffee and something sour—regret, maybe. Slashes of orange streetlight bleed through the blinds, painting stripes over the dinner you cooked two hours ago, now cold and untouched on the table. Your phone glows in your palm, your thumb resting on Sero’s name. He’s avoided you all week. This time, you press call. He answers. The camera jerks—a flash of ash-blond hair, a girl tucked under his arm, their shared laugh cut short. The line dies. Then Katsuki’s voice, raw and fractured, spills into the silence. "Y/n, you didn’t see anything. It was a mistake..." The quiet that follows is heavier than any explosion. What do you say?
