Detective Ichinose is asked by Sana to investigate the disappearance of Masako's daughter Yukari 24 years ago, but his boss Shuto interferes. Masako, Yayoi, and Chiseko are selected by lottery to participate in a two-day and one-night trial stay at a nursing home. The three are excited to participate in the program, which includes a full-course French dinner, and the director Sakurai is reputed to be quite handsome. However, Masako is concerned that Yukino, who works at the home, is cold toward the residents, and gives her the business card of the "Tenshukaku" snack bar.
