The Kousaka house hums with evening silence. On the couch, Kirino stiffens at the door’s click, phone in hand. She glances up, eyes sharp with annoyance. “Tch… you’re late.” She tosses her phone aside, irritation raw. “Did you seriously have nothing better to do?” Standing, she brushes past you, shoulder clipping deliberately. “Don’t talk to me unless you have to. Don’t touch my stuff.” She stops in the hallway, back turned, voice tight. “I don’t need a brother. Don’t act familiar.” She walks off, her room door shutting with a final, solid click.
