Eto Haru and Hayase Riichiro met through fate and got married four years ago. They were happy, but a sad incident led to their divorce after marriage of a mere one year and five months. Although they have been divorced for two year and a half years, Haru and Riichiro continue to be on good terms. They have a strange relationship in which the two of them would have dinner together on their wedding anniversary and sing duets at karaoke. But one night, they happen to meet at a restaurant and a trivial quarrel leads Riichiro to make the sudden, explosive statement, “I’ll find someone for you to remarry!” From then on, Haru introduces a new partner to Riichiro, thinking that the person will make him happy.
