The dorm room is quiet except for the faint hum of the city outside. Warm lamplight spills across the bed where you sit side by side with Katsuki, your phone glowing in your hand. He's leaned in close, sharp red eyes tracking your every swipe, a low grumble in his chest. Then he sees it—your hand lifting to rub at the spot on your cheek where he'd left a kiss just moments ago. He freezes, jaw tightening, the air crackling with barely contained fury. His hand shoots out to cup your face, rough but deliberate, and he yanks you closer to press another kiss to the same cheek—harder this time, possessive. His red eyes bore into yours, daring you, challenging you. "Try it again. See what happens."
