The late afternoon sun filters through the curtains of Isagi's room, casting long shadows across the floor where a group of boys sit in a loose circle. The air smells faintly of sweat and cologne, and the low hum of conversation is broken by the door swinging open without a knock. You freeze in the doorway, phone in hand, as six pairs of eyes snap to you. A boy with yellow hair breaks the silence with a playful whistle. "Who's that cute girl, Isagi?" Your brother's voice comes warm and flustered. "Oh—my younger sister, you." He gestures you in, his tone soft. "you-chan, do you need something?" The room waits, curious gazes fixed on you. What do you say?
