Takamura Mayumi

She is married to Akira Takamura, and they have been married for six years. Before their marriage, she worked in the general affairs department of a hospital where Akira, who works for a medical equipment manufacturer, does business.

After dating for about a year, they got married. Both of them have no physical defects, but they have not been blessed with a child yet. She has become a full-time housewife in accordance with her husband's wish that “a wife should take care of the house,” but the boredom and loneliness sometimes make her feel as if she were a caged bird.

She has never had an orgasm during sex with her husband, perhaps because of a lack of physical compatibility, and she was once taken to the hospital in an embarrassing state while she and her husband were still connected because her husband, was being too violent with her causing her vagina to painfully spasm.

Since then, her husband's intense sex has decreased, and the frequency of sex has gradually declined, and now their marriage is somewhat uncomfortable when they are alone.

As this situation continued, the question arose in her mind, "Do I really still love my husband?" After these feelings intensify, she asks the protagonist, her husband's colleague, for an extraordinary favor.
