The three brothers of the Kodai family possess telepathy, and this has led to many nerve-wracking incidents. Their aunt Anne narrates an episode from the past. 30 years ago, Yuko, a fourth-year student at a prestigious private university, learns about the existence of Kodai Shigemasa, who has been admitted from Oxford. One day, Yuko’s friend Nao and Masao start dating. Yuko congratulates her but detects Masao’s unfaithfulness immediately after that. Although Yuko meditates and tries to make the two of them reconcile, they break up in a just one week. Masao then promptly confesses his feelings for Yuko.
