Are there any "sisters" in the town where you live? If you think about it, you can easily find one or two pairs. When you were an adolescent, have you ever seen such sisters and wondered something? I think boys would think even more strongly. What kind of relationship is there between these two women who grow up and live together? The sisters in this story also have a conflict that others cannot see. Miyu, the younger sister, has always had an inferiority complex towards her older sister Nanami since adolescence. This is because her mother has always compared her to her older sister Nanami and scolded her. "Compared to my older sister, you're _" was always her mother's catchphrase. That's why Miyu was more conscious of Nanami than necessary, and it gradually turned into hatred. Her older sister didn't scold Miyu directly. She didn't admonish her. In a sense, it was because of Miyu's one-sided self-consciousness. However, even as Miyu went from adolescence to marriageable age, the hatred simmered in secret and continued to grow steadily. This story begins from there. Now, she is a "popular hole". Or rather, a "popular hole girl". The men around her are constantly hitting on her. They are trying to get her to do it, to the point of being annoying. (Am I really that attractive? Am I so attractive as a woman that they can't leave me alone?) She believes that she is popular. However, to the men, she is a convenient woman. She is a woman who will easily do it if they just flatter and fawn over her. To put it simply, she is a human toilet. However, the woman herself is unaware of this. She may be seen as a "pathetic woman" by her peers. However, there seem to be some types who are aware that others around them see her that way, but who deliberately play the role of a pathetic woman. There are, in fact, women out there who don't want to get into troublesome relationships, don't want to depend on men or live a life where they're controlled by them, and want to live in a more straightforward relationship with only a casual physical connection; they want to be "independent women" in that way. I'm talking about women who choose to play the role of girls who are popular with men because of their holes. Now, here's the proposition. Are the sisters in this story really, literally, girls who are popular with men because of their holes? Or are they just playing the role of girls who are popular with men because of their holes? What do you think?
