During puberty, have you ever felt something when looking at sisters? For men, these feelings might be stronger. In this story, the sisters harbor unseen tensions. The younger sister, Miyu, has long carried deep inferiority toward her older sister, Nanami, ever since their mother constantly compared them, scolding Miyu with phrases like, "Why can't you be more like your sister?" These words carved a permanent wound in Miyu's heart. Her constant awareness of Nanami gradually twisted into hatred. Although Nanami never directly reprimanded or lectured her, her oblivious self-assurance further distorted Miyu's psyche. From adolescence into adulthood, this resentment quietly smoldered and grew. This story begins from that very point. On the other hand, the concept of "hole-popular" women is also intriguing. Always approached by men, constantly seduced, surrounded to the point of annoyance—she believes herself truly desirable. But to men, she's merely convenient, an easy lay. Frankly, nothing more than a cumdump. Yet she remains unaware. Other women may see her as a "pathetic girl," but some women, sensing how they're perceived, deliberately play that role. Tired of love, unwilling to be toyed with by men, wanting only no-strings-attached, purely physical relationships—such women do exist. So, are these sisters genuinely hole-popular? Or are they merely pretending to be? That answer is left to the viewer.
