Akiko (Aoki) has to take care of her older sister's only son, Tomoya, who has to work day and night to pay off her older sister's husband who ran away leaving behind a debt. Akiko and her husband had no children, so it was refreshing to live in the same house as a young boy. Akiko, who lost her father at the most important time of her life, treats Tomoya more kindly than necessary to Tomoya, who has a hard time getting along with her mother. Such excessive Akiko's kindness invites the two to forbidden sexual intercourse.
