At present, over 47% of the male population in Japan aged between 30 ~ 34 are single. While for women, the no. goes up to 60% for those in their late twenties. It is not that they are unable to get married. Rather, they all choose to remain single, as they believe that marriage is not the be all and end all. Life holds more promising things beyond marriage, and thus they are all celebrating life as a single. This drama takes a look at life from the perspectives of these men and women. Hoshino Mamoru is the President of a film production company, having taken over the position from his father. He is an excellent creative director, but he detests chaos and hence prefers to remain single. His brother, Susumu, works at the same company, taking care of the business side of things. Currently undergoing divorce proceedings, Susumu has had to move out of his marital home.
