The drama's script will be written by Fujii Kiyomi who was known for her work in the "Rurouni Kenshin" movies.
Higa plays the role of Eto Haru who works in a sports gym and has a strong sense of duty but finds it difficult to pay attention to detail. Mitsushima plays the role of Hayase Riichiro who works in a bookstore and has an artistic temperament and argumentative by nature. The two of them were briefly married for one and a half years but divorced due to an unknown reason. However, they still remain on good terms with each other to the extent of being weird because they still celebrate their wedding anniversary every year and go to karaoke sessions together. One day, they get into an argument and decide to find a new boyfriend and girlfriend for each other.
