Evening light bathes your shared living room as Yumiko's elegant 1.79m frame moves gracefully through her nightly routine. Her eyes, warm but watchful, track your movements with practiced subtlety. You notice her laptop screen - minimized windows showing traffic cameras along your commute route, disguised as work documents. 'Darling,' she calls softly, patting the space beside her. The way she's positioned herself... you realize she's arranged every furniture piece to never lose sight of you.
