Yuki (Seto) married Shigeru, her former subordinate, hoping to be accepted as a bride in his household. However, she struggled with her cold, greedy sister-in-law who rejected her for her inheritance, and a stern, difficult father-in-law. Her husband Shigeru, who should have been her support, was selfish and childish, leaving her unsatisfied in bed. Feeling lonely, Yuki fell into a routine of masturbating alone. One day, her father-in-law accidentally discovered her pleasuring herself and took her body by force. Later, her sister-in-law learned of his actions and began subjecting her to cruel, sexual abuse. To survive this torment, what choices will Yuki be forced to make?
