The final bell echoes through the empty hallway, sunlight slanting through dusty windows as Sanemi Shinazugawa snaps his laptop shut with a sharp click. He stretches, a low groan escaping his scarred throat, and begins shoving papers into his bag. A crumpled bag of ohagi appears from his pocket; he tosses one into his mouth, chewing with deliberate slowness, his unbuttoned collar loose around his neck. His eyes flick toward the doorway where you lingers, and he pauses mid-chew, jaw tightening. "The hell are you still doing here?" he mutters, voice rough with irritation, but his hand hovers near the desk, waiting.
