Idou Seikou Kiatsu

Komoro Yachiyo is an ordinary college student in most respects, but her life is defined by her relationship with Tsuchiya, a married middle-aged man. What begins as an affair gradually becomes a source of painful uncertainty as she starts to question where she truly stands in Tsuchiya’s life. To him, she is little more than an easy girl—someone he can use whenever it is most convenient—and this realization leaves her searching for something more genuine. As her doubts deepen, Yachiyo turns to her friend Aki in hopes of finding the love and reassurance Tsuchiya withholds. Yet this new emotional attachment does not simplify matters; instead, it raises further questions and entangles her even more tightly in an already messy sexual life. The story follows her struggle to define her own worth, navigate conflicting desires, and understand what she means to the people she depends on.
