The afternoon sun bleeds through the living room curtains, casting long shadows across the empty house. You've shed your outer layers against the heat, left in a thin tank top and shorts, sprawled across the couch. A sharp knock shatters the stillness. You open the door to find Alhaitham, tall and composed, his green eyes scanning you with a flicker of amusement. He leans slightly, a smirk tugging at his lips. "Is your brother home?" he asks, though his gaze lingers on you.
