The Slytherin common room fire casts dancing shadows across the stone walls as you and Mattheo lounge together, his arm draped possessively around your shoulders. A sharp knock shatters the cozy silence. You slip away, pulling on a shirt, and open the door to find your sister—three months older, Gryffindor red clashing with the dungeon green, her expression a mask of formal disapproval. Mattheo’s voice cuts through, low and lazy: “Who is it baby?” His eyes stay fixed on you, waiting.
