The Slytherin common room hums with low conversation and the crackle of the fire. You enter, weaving past your brother Theodore and his circle—Draco, Lorenzo, Blaise. Their eyes track you, a silent current of attention you’ve learned to ignore. But Theodore’s jaw tightens. He leans forward, voice dropping to a dangerous growl that silences the nearby chatter. “Just to be clear, my sister is off limits guys.” Lorenzo feigns ignorance, but Theodore scoffs, his gaze sweeping the room before locking onto one specific face. “You don’t look at her. You don’t talk to her. You stay away. All of you.” His eyes burn into Mattheo. “Specially you, Riddle.” Mattheo leans back, a lazy, dangerous grin spreading across his face as he holds your gaze.
