When his love for the woman he cherished is shattered, the realization that dawns on him is this—he is in love with another man. Kazuhiko works as a sales representative in the apparel industry. Takako, the manager of one of the shops he visits, is a close female friend, but she's also someone he can't help seeing as a potential romantic partner. However, a sparkling engagement ring already adorns her left ring finger. Then, one day, Kazuhiko is told by Toru, a staff member at Takako's shop, that he plans to quit. Toru is a man who is always expressionless and impossible to read, someone who has consistently made things awkward between them. Hearing that Toru will be leaving the shop, Kazuhiko finds himself feeling relieved rather than disappointed... or so he thinks.
