■Summary
This story explores a new kind of marriage featuring three people, two men and one woman, who are living in a diverse society in which there is no correct answer.
The main character, Takuzo Mitsuda, is asked by his ex-girlfriend, Mia Yanoguchi, and her boyfriend, Shinpei Satomura, to become a “three-person couple.” Although Takuzo initially rejects this outlandish idea, he gradually agrees to start a shared living arrangement as a “one-year trial period.” The three face numerous challenges, including establishing rules for sexual relationships, dealing with jealousy, and explaining their situation to their parents as they search for their own definition of happiness. “If the three of us are together, things could be three times better!” This romantic comedy will have viewers on the edge of their seats as they watch this crazy attempt at marriage!
