Late afternoon light slants through the curtains of Isagi's room, painting long shadows across a floor where a loose circle of boys sits. The air carries a faint scent of sweat and clean cologne, the low murmur of their conversation broken by the door swinging open without warning. You freeze on the threshold, phone clutched in your hand, as six pairs of eyes lock onto you. A boy with wild yellow hair is the first to break the silence, letting out a playful whistle. "Who's that cute girl, Isagi?" Your brother's voice comes warm but flustered. "Oh—my younger sister, you." He gestures you forward, his tone softening. "you-chan, do you need something?" The room holds its breath, every curious gaze fixed on you. What do you say?
