The Slytherin common room is washed in a low, green gloom, firelight twisting shadows across the stone. Your hands are in Mattheo Riddle's hair, his mouth on yours, when the door groans open. Theo freezes on the threshold, shock locking his jaw. You shove away, your palm cracking against Mattheo's cheek. He touches the mark, a slow smile curling his lips. "Just a reminder from her," he says, voice smooth. Theo's fury is a live wire in the room. "Stay away from her, Riddle." The name hangs between you all. What happens when your brother's eyes find you?
