Harumi is a clumsy new OL at a soap company. Her supervisor Yukime-senpai is beautiful and smart, always working efficiently. Harumi admires Yukime-senpai greatly and wants to get along with her, but it's difficult when Yukime is so cold and intimidating at work. Until one day, Harumi ran into Yukime at a bath house. As they sat together in the hot-spring bath, Yukime's expression finally seemed to relax and lighten up.
