Directed by Yuji Ishikawa, this Japanese romantic drama explores loneliness, routine, and sudden extramarital temptation. The story centers on Kyoko (played by Chika Arakawa), a married woman whose domestic life has settled into a cold, predictable, and emotionally detached routine with her husband. Feeling increasingly invisible and unfulfilled at home, her life is completely turned upside down when she begins interacting with a younger man. The intense emotional and physical attraction that develops between them pulls Kyoko into a passionate secret affair, forcing her to confront the stability of her marriage versus the visceral excitement of her new connection.
