The sex scene opens with a flashback to the beginning of the novel, when the sex scene is set in the apartment of a young woman named Masaki. Masaki has just returned from a trip to Europe, where she met her current husband, who is also a young man. The young woman, Masaki, has a sexual desire for her current lover, but she does not know who it is. She is afraid that Masaki's love for her will make him a rival for her affections. When Masaki asks Masaki if she wants to have sex with him, the young woman replies that she would rather have sex in a private jet with Masaki than in a public room with Machiguchi.
