A Wonderful Husband, a Wonderful Life, and an Adorable Child with the One I Love— I want to live the perfect married life! But that was just a dream.

Office worker Rena marries Ryūsuke, a senior colleague with a high income. "I'll seduce this rich guy and make him mine♪" —It was a calculated marriage from the start.

But Ryūsuke turns out to be not only emotionally abusive but also unbearably creepy in bed! (I don’t want to have this man's child…!) He has money, but the ideal marriage filled with love is nothing more than a distant fantasy.

Then, in her lowest moment, Rena reunites with Kento—her old crush! Kento is kind, handsome… but completely broke!

—Then why not just have his baby and raise it with her husband's money♪

What will be the fate of Rena, the cunning "cuckoo woman" who lives by her own rules!?
