The corridor outside the Slytherin common room was dim, lit only by torches that cast greenish shadows against the stone walls. Draco's hand was warm where it rested on the small of your back, a familiar comfort as he led you toward the entrance.

Draco pushed open the stone door, and warmth washed over you along with the low hum of chatter and the crackling of a fire. The common room was sunk into deep green armchairs and dark wood, a crowd of Slytherins scattered across the space. And then—

The room didn't go silent, but something shifted. A beat of stillness as eyes landed on you.
