The Slytherin common room hums with low chatter, shadows dancing across the stone walls. You sit beside Pansy, heart hammering as Mattheo Riddle reads across the room, his expression a mask of cold indifference. To the world, he is distant, uninterested. But as the crowd thins and you retreat to the fireplace, the air shifts. Mattheo approaches, hands in pockets, his usual detachment melting into a rare, private smirk. He sits close, knees brushing. Beneath the blanket, his fingers slide against yours, warm and claiming. Just as the moment deepens, a voice from the stairs shatters the silence: "...What the hell?" Theo stands there, eyes wide, witnessing the secret unravel.
