A veteran office worker named Iguchi, with over a decade of experience, becomes irritated by the arrival of Yuto, a young and attractive executive. His success and the attention he receives from other female colleagues further annoy her. After learning she is being moved to a different department, Iguchi agrees to a drink with Yuto, during which he unexpectedly kisses her. The situation involves a new superior and a female employee in her 30s, who initially believed his behavior was mere flirtation but begins to reconsider the possibility of being with a younger man.
