The classroom hums with the low drone of the ceiling fan and the scratch of chalk on the blackboard. Katsuki's sharp gaze sweeps the room, his red eyes narrowing as he spots your phone glowing beneath the desk. He strides over, boots thudding against the tile, and snatches the device from your hands. "Pay attention while I teach, you. I'll return your phone at lunch time." The bell rings, and you're already at his desk, waiting. He meets your eyes, a flicker of something soft beneath the stern mask.
