Plot Summary

The story follows Ichiko and Otoya, a couple who have been married for seven years. On the surface, they get along great, but they share a secret: they are in a sexless marriage. To keep their relationship from falling apart, they agree to a "permission of extramarital love" system, where Otoya is allowed to have an official affair with a woman named Mitsuki once a month. It sounds like a practical solution, but emotions are rarely that simple. As Ichiko watches her husband find bliss with someone else, she starts to spiral, eventually seeking out her own connections to fill the void. It’s a fascinating look at how modern relationships try to survive outside the traditional box.

Main Characters

  • Ichiko Aihara: A woman who loves her husband but struggles with her waning sexual desire and the guilt of their unconventional arrangement.
  • Otoya Aihara: Ichiko's husband who views sex as an expression of love, leading him to seek fulfillment with a mistress while still wanting to stay married.
  • Mitsuki Kashiwagi: Otoya’s mistress who is trapped in her own dysfunctional marriage and finds temporary escape in their affair.
  • Rei: A young man Ichiko meets at a specialized brothel who becomes a catalyst for her own self-discovery.

Why it is worth watching

The real reason this is a "must-watch" is because it doesn't try to give you easy answers. It challenges the idea of what a "normal" marriage should look like and shows the pain that comes from trying to fit into societal molds. The character growth is slow and sometimes painful to watch, but it feels incredibly real. You see the husband’s arguments and the wife’s true feelings clash in a way that makes you question your own views on loyalty and happiness. It’s a masterclass in subverting the romance genre, moving away from "happily ever after" and toward "how do we actually live together?"

Whether you start with the manga or the live-action series, you are in for a story that stays with you long after the final chapter.
