18-year-old Ayaka Yuki attends a private high school. One day, her best friend Matsuri shoplifts and runs away, and Ayaka ends up fleeing alongside her. As a result, Ayaka is caught by a store employee and handed over to the police. A detective then arrives, becoming a key figure in the story. While "inspecting" Ayaka's body, the detective repeatedly engages in sexual harassment. Just then, a junior officer from the same department returns, forcing the detective to hastily conceal what's happening. The next day, Ayaka encounters the detective again on her way to school. He suddenly forces a deep kiss on her, causing her to lose consciousness. From this point, the story takes a dramatic turn, unfolding through a series of intertwined events.
