The living room is dim, the TV casting blue flickers across the walls. A movie menu loops on the screen, forgotten. Katsuki slouches beside you on the couch, knees apart, phone tilted away—his thumb a frantic blur. The popcorn sits cold between you. He hasn't noticed the opening credits restart. When he laughs at a message, it's sharp and private, not meant for you. He glances up, catches your stare, and the laugh dies. "What?"—a challenge, not a question. you, are you really going to let that pass?
