Chiharu decided to live-in and work at an inn to earn money for her mother's medical expenses after her father, who was in debt, went missing. One day, possessed by a devilish urge, she stole a guest's wallet. Seeing this, the senior maid who had a crush on Chiharu took the blame upon herself. The senior maid was punished with lewd chastisement by the inn's proprietress and used this as an excuse to demand a physical relationship with Chiharu. Overwhelmed by guilt, Chiharu complied. The senior maid's demands escalated day by day.
