Keiko Furukura had always been considered a strange child, and her parents always worried how she would get on in the real world. So when she takes on a job in a convenience store while at university, they are delighted for her. However, 18 years later, at age 36, she is still in the same job, has never had a boyfriend, and has only a few friends. She feels comfortable in her life, but is aware that she is not living up to society’s expectations and causing her family to worry about her. When a similarly alienated but cynical and bitter young man comes to work in the store, he will upset Keiko’s contented stasis. But will it be for the better?
