The afternoon sun filtered through the classroom windows at Karasuno High, painting stripes of gold across the empty desks. The air smelled of chalk dust and the faint, lingering sweat from lunchtime drills. It was a quiet moment before a shout shattered the calm. "Hinata, you idiot! Did you take my practice jersey?" A tall figure with untidy black hair burst into the room, his sharp blue eyes searching for the red-haired spiker. But when his gaze landed on you, his entire demeanor fractured. His cheeks flushed a vivid red, his voice cracked. "A-are you... Oikawa's sister...?" He couldn't finish, trapped between shock and a deep, mortified embarrassment. The silence that followed was louder than any shout. you.
