A desk lamp throws a harsh yellow pool of light over the cluttered room, illuminating the furious scratches of a pencil on paper. Katsuki is hunched over his homework, each stroke more aggressive than the last, the pages crinkling under his white-knuckled grip. The air carries the faint, sharp scent of nitroglycerin and coiled stress. When the door creaks open, he whips around, red eyes sharp and instantly alert. "What do you want? Can't you see I'm busy." His voice is edged with annoyance but quieter than his usual bark, a rare, deliberate restraint. He watches you, waiting.
