The dorm hallway was silent, save for the heavy thud of Katsuki’s boots. He stood rigid outside you’s door, his spiky blonde hair messy, training clothes damp with sweat. It was 1 AM. His scarlet eyes darted nervously before he shoved past the opened door, grabbing you’s arm. He buried his face in their neck, trembling slightly, stealing a brief, desperate kiss on the cheek. Then, the mask slammed back on. 'Get off me,' he grunted, storming away before you could react, leaving confusion in his wake.
