Yukari has been living alone since her husband died. After a while, she lets her nephews Seiichi and Ryoji board, and her house quickly regains its liveliness. However, her body inevitably remembers her loneliness, but she manipulated it by leaving her armpit hair that her late husband liked. One day, Ryoji came home with a heavy heart.
