Even while knowing that it's a trap, the sweet scent is irresistible…

Just an unremarkable woman, Yae has mostly been working temp jobs. Then she runs into her high and mighty, childhood friend Takumi Natsume, who has become an architect. In exchange for staying for free at his high-rise apartment, she agrees to take on the role of the fake spouse of him! At her friend’s wedding after-party, Yae reunites with her ex. He takes her out on a date at a fancy French restaurant, but guess who is at that restaurant? None other than Takumi, who happens to be there on business! Yae’s heart wavers between her fake husband, who is full of himself, and the sweet her ex?! A little naughty and very extravagant! The third volume of a Cinderella-like love story that has started with a lie is full of unexpected turns of events!

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!

Yae is radiating happiness after Takumi proposes to her. That's when Ayumu, the eldest Natsume son, comes to visit from NY.

They hurriedly announce their marriage to them and go to greet them, but then they find out there's a Natsume Family rule that prevents them from having a wedding...?!

While at the mercy of the pompous Takumi, Yae’s also starting to fall for the sweet side of him.

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!
