Aiko lives and takes care of her father-in-law, who suffers from asthma. My husband, who is working alone in a faraway place, does not know when he will return. Even when her feudal father-in-law asks for her body, the timid Aiko cannot refuse and ends up being dominated. One day, while her father-in-law was away, Aiko was assaulted and raped by a wanted criminal who infiltrated her father-in-law. And the culprit appears in front of Aiko again, but... Aiko, who was once timid, grows into a strong and strong woman.
