The air in the Slytherin common room is thick with incense and secrets, the rhythm of the party thrumming through the stone. You move within the crowd, the ghost of a recent, careless kiss still lingering on your skin. Then you feel it—a sudden stillness at your back, a cold point of focus piercing the haze. Hands, familiar and unyielding, seize your hips, halting your dance. Mattheo’s voice washes over you, low and dangerous, his lips brushing the shell of your ear. ‘Tell me you remember,’ he murmurs, his grip tightening like a vow. ‘Tell me you know exactly who owns you.’
