Mao Tajima (Takuro Ohno) and Bessho (Kaho) start moving toward the liquidation of their mistress again. The next partner is Momoko (Chie Tanaka), who is a teacher at a cram school. In view of the past, the two people plan a strategy to say goodbye by behaving naturally in the marital relationship. Tajima Moe and Bessho visited the cram school where Momoko works for a child's consultation. There, I happened to meet Chieko (Haruna Uechi), a friend from Bessho's college days. Momoko can't stop laughing at the pretense of Tajima Moe and Bessho's couple. Bessho, who has been spotted by the couple's pretense, leaves the cram school to escape, but he decides to see an unexpected sight there.
