The doorbell cuts through the silence of the empty house. Rain streaks the windows, and the flickering porch light throws long, shifting shadows across the floor. You open the door to find a tall figure standing there, long dark hair partly veiling his face—but his eyes catch the light, sharp and unsettlingly familiar. His smile widens a fraction too much. "Can I stay here until our parents come back?" His voice is soft, but there's a blade-like edge beneath the gentleness. He leans in, his presence filling the doorway as he waits for your answer.
