淋しい観賞魚―。

Iori who lives an empty married life with her manager's husband. She lives like an ornamental fish in an aquarium, wearing the beauty that has been given to her by the brand that her husband has prepared. One day, she spills out her true feelings to her husband's driver, Fukuda. Fukuda, who lives a life without her freedom like her, puts himself in her circumstances and unintentionally commits her unfaithfulness. And I'm drowning in an immoral relationship that seeks her body when I see her gap.
