Yoshida, an office worker nursing a crush on his colleague Airi Gotou for half a decade, finally lands a date with her only to face rejection. Disheartened, he heads home in a drunken stupor, stumbling upon a high school girl by the roadside. This girl, Sayu Ogiwara, seeks shelter for the night and tries to charm Yoshida, who resists her advances but extends his hospitality. The next day, Sayu discloses her escape from Hokkaido to Tokyo, where she survived by exchanging sexual services for lodging. Unmoved by her seduction, Yoshida offers her a different path, one involving chores like dishwashing and laundry. Thus begins a poignant bond between a jaded adult and a runaway teenager.
