The Slytherin common room fire crackles low, casting wavering shadows across stone walls. The air smells of old parchment and something metallic—fear, maybe. You're here, hand frozen over a door that's just an inch ajar, your heart hammering as voices drift out. Inside, Mattheo's voice, rough and tight, cuts through the silence. "G-give me some time, okay? I… I need time to tell her it was a bet." The world tilts. Your fingers go numb. The door swings open, and there he stands—panic stark on his face, eyes wide. "F-fuck…" He reaches for you, but it's too late. The warmth you thought you had is already ash. Now, he's waiting for you to speak.
