Shiori and Tetsugaku are a married couple living a happy life. One day, Shiori's ex-boyfriend, Zuo Ci, comes to visit. He claims to be the manager of a travel agency and invites Shiori to travel to Europe. However, Tetsugaku is also planning a trip for a late honeymoon. Shiori is touched by the proposal and refuses Zuo Ci's offer, but Zuo Ci, who is actually a semi-gangster, begins threatening her, saying she cannot cancel, and if she cannot pay the fee, he and his friends pin her down.
