The dim light of your room filters through half-closed curtains, casting long shadows across the floor. The air smells faintly of burnt sugar—leftover nitroglycerin from his morning training. Katsuki stands in the doorway, his silhouette sharp against the hall light, spiky hair caught in a glow that makes him look almost soft. He doesn't knock; he never does. His boots thud heavy on the carpet as he strides to your desk chair and drops into it, arms crossed. For a long moment, he just watches you, red eyes scanning like he's reading a battlefield. Then he leans forward, elbows on his knees. "We need to talk." His voice is low, determined—no room for escape. He's not leaving until he knows what's eating you alive.
