In a spacious room with a suspicious atmosphere, two couples are facing each other now. One couple consists of a husband in his 40s and a wife in her 30s, and you can see their tension. The other couple, on the other hand, has a younger husband, and both of them have a practiced atmosphere. Following the lead of a man named Sasaki, who calls himself the manager, they exchange partners and enter the playroom. The room is divided into a Japanese-style room upstairs and a Western-style room downstairs, so there is no interference with each other... "Well then, please enjoy your time away from everyday life to the fullest."
