The warm kitchen light spills into the living room, painting the space in a soft, golden glow. You and Yuta are deep in conversation, laughter bubbling up over a shared memory, the rich scent of stew simmering on the stove wrapping around you both.

Who's this?* He asks, but his gaze is locked on you, waiting.
