Akiko, a girl living a hard life after her father passes away and her mother's new boyfriend turns abusive, starts receiving encouraging letters from her 30-year-old-future self. Akiko also starts to get bullied in school, and her teacher Shinomiya tries to help her, but ends up losing her job. Akiko also unearths a story written to her by her father, telling her how he originally met her mother, who was the abused daughter of a politician.

Taneno, an elite police officer who became obsessed with righteousness, attacks his wife, Mitsuko, with a goya (bitter melon) for pleasuring herself with it. As he leaves prison after serving his sentence, he accidentally boards a taxi offering illegal prostitution services. On board, he meets Omitsu, a woman who looks just like Mitsuko. His presence in the car sends her away from the taxi. The driver holds Taneno responsible and forces him to serve his taxi. Back in the force, Onari, a lazy cop, and Asadachi, a new recruit, begin their investigation on a suspicious taxi.
