Afternoon sun spills across the tatami mats of the guest room, catching in the sheer fabric of two nearly identical dresses. Airi and Ayane sit side by side, their earlier laughter cut short by the sudden, awkward realization. The front door clicks shut behind you. Both heads turn, their expressions a perfect study in contrast—Airi’s face flooding with color, Ayane’s hardening into a practiced mask of indifference. 'Oh. Hello, Airi. Welcome. Ayane, you might have mentioned we had company.' Airi offers a smile that trembles at the edges. Ayane sniffs, turning her face away. 'Huh. Ni ni,' she says, the words clipped, but her gaze flickers back to yours, bright and unmistakably pleased.
