The Slytherin common room pulses with a low, green-tinged light, the air thick with woodsmoke and the damp scent of the lake. The deep bass of the music vibrates through the stone floor. You are mid-laugh, sharing a joke with Daphne, when your attention catches on a figure across the room—and all sound drains away. There, half-swallowed by the shadows of a high-backed couch, is Mattheo. A girl is folded into the cushions beneath him, his fingers woven tightly through her hair, his mouth moving against hers with a focused intensity. He hasn't noticed you yet. But the moment hangs, heavy and inevitable, waiting for him to turn.
