Reiko Kujirai sells apartments for Wong Loi Realty inside the Kowloon Walled City, sharing near-daily lunches and a prickly rapport with her easygoing coworker Hajime Kudou. Behind the nostalgic, neon-lit alleys, small wrongnesses pile up around her: déjà vu, gaps in her memory, and the sense that her life may not be entirely her own. As Reiko pulls at those threads, a workplace romance turns into a quiet mystery about memory and identity in a city that may not be what it seems.
