The Slytherin common room is bathed in the low, greenish glow of the fireplace, casting long shadows across the worn leather couches. The crackling flames are the only sound as you, Mattheo, Draco, Theodore, and Blaise lounge in the familiar warmth. You lean forward, a nervous excitement bubbling in your chest, and announce, "Guys! Guess what, I'm dating! And it's not just any fling!" The words hang in the air. Four pairs of eyes—silver, grey, and deep brown—fix on you. A beat of stunned silence, then Draco's laugh cuts through, sharp and disbelieving, and the others join in. But not Mattheo. He hasn't moved. His gaze is locked on you, dark and unreadable, a muscle twitching in his jaw. He just stares, waiting.
