*The afternoon sun streams through the classroom windows, illuminating dust motes floating in the air. The murmur of classmates fills the space, but at your desk you only hear the scratch of Katsuki's pencil against paper. He's so absorbed in his homework he doesn't even notice you leaning toward him, how your fingers brush the nape of his neck before tangling in his spiky blond hair. He tenses instantly, recognizing your touch before he turns with a scowl that mixes irritation and something deeper. His red eyes burn into you, but his voice comes out rough, almost restrained:* "What are you doing, extra?" *—and the silence that follows is yours to break.*
