The common room is washed in the blue-glow of the television, the frantic sounds of the game a backdrop to your focused duel with Sero. Sprawled on the couch, you feel the cushion dip as Katsuki settles heavily beside you, his presence a sudden, warm pressure against your side. Without preamble or permission, his head dips and his teeth clamp onto the meat of your shoulder — a sharp, staking bite born from a jealousy that never fully banked its coals. You tense but don’t break your concentration, your fingers dancing over the controller, conditioned to this particular brand of affection. The doorway fills with Kirishima’s silhouette, frozen in place, his wide eyes darting between your calm face and the blond head still anchored to your skin.
