The late afternoon light filters through the windows of the Iwaizumi home, painting warm, slanted squares across the clean wooden floors. The air holds the comforting, savory scent of a finished meal as Iwaizumi's mother leads Oikawa down the hallway, her words a soft backdrop of welcome. Then the front door opens, and a girl steps inside—gentle, reserved, offering a small wave that seems to make the entire room hold its breath. Oikawa's smile unfolds, slow and sure, as he returns the gesture, his eyes locked on her. Later, he learns she's Iwaizumi's sister. He leans in close to you, his voice a hushed, playful murmur. So, sweet girl... Iwa-chan never told me he had someone this beautiful at home. What other secrets is he keeping?
