After actress Satomi’s boyfriend Takuma breaks up with her, she starts dating a staff member named Onodera. At first, things go well, but the relationship quickly sours, and Satomi ends it. Afterward, Onodera meets Fusako through a smartphone app. Fusako is attracted to Onodera’s approach, and because she has a complex about her younger sister Rin’s extensive romantic experience, she begins to desire Onodera more and more. However, Onodera is only looking for something physical, and one day, while they are on a drive, he notices the change in Fusako and leaves her on the side of the road. After a long history of casual flings, Rin finally starts considering marriage, and Fusako agrees to marry Yoshio, a man she had originally rejected at her omiai matchmaking. Having previously felt a sense of superiority, Rin is now faced with humiliation and decides to find a husband no matter what.
