Yae is an unremarkable girl who temps for a living. She loses her home and job in one stroke and is, at 29, at her wits’ end. Then her childhood friend Takumi appears before her. A good-looking, successful architect, he lives a glamorous life. In exchange for free accommodation in his skyscraper condo in the heart of Tokyo, Yae acts as his fake wife?! This is the story of a fake marriage to a smug, handsome architect!
While at the mercy of the pompous Takumi, Yae’s also starting to fall for the sweet side of him. But Takumi has no desire to get married and his fake wife won’t ever become the real deal… Well, that’s what she thought when Takumi proposes to Yae, saying, “Wanna get married?”! The two finally spend the night together… Then, Ryo-san, Takumi’s sempai from when he was an office worker, appears before the two who are at their peak of happiness (or should be) and puts Yae in a real pinch!
