When Giselle Lemaire discovers that her husband Oliver Lefebvre is cheating on her with his assistant, whom he impregnated, and that they are also planning to humiliate her during the company's anniversary celebration, she decides to take revenge on them. Thanks to a chance encounter with Nathan Dubois, the man whose perfume formulas her husband stole and launched as his own, she makes a deal with him in exchange for his help.
Yes, the man agrees to marry her and help her recover the laboratory that her husband and his parents stole from him. In return, she will give him the name of the person who sold his perfume formulas to the Lefebvres and various formulas to defeat his enemy.
After Giselle obtains a divorce with Nathan's help, she marries him a few days later and begins to deliver on her promise, leading her company to surpass Oliver's in a short time.
However, Nathan begins to fall in love with his wife, and when he confesses this to her, she tells him that they had only made a two-year deal, and that they should divorce after that time. He refuses and decides to win his wife's love by following the advice of his assistant, Scarlett.
Thanks to Nathan's efforts, Giselle agrees to continue their marriage as she is also falling in love with him. However, Oliver, resentful of seeing his ex-wife happy in another man's arms, tells Nathan that Giselle was the one who helped him improve all the formulas he stole. Feeling betrayed, Nathan kicks her out of his house and asks for a divorce.
Without giving her a chance to explain, they begin the divorce process. It is then that Giselle discovers she is pregnant with Nathan's child and tells him about it. But when he threatens to perform a paternity test on the baby and take it away if it's his, she lies to him and makes him believe it's Oliver's.
After divorcing for a second time, Giselle moves to the United States, where she begins working as a perfumer. She is only forced to return to France when she is informed that there is a lawsuit against the Lefebvres for causing the fire in which her parents died. At the same time, Nathan seeks her out after learning that everything Oliver did was to separate them, and while Giselle did help him improve his products, she never knew they belonged to the Dubois.
When Nathan finds her and apologizes, Giselle rejects him and clarifies that she has only returned to make the Lefebvres pay for everything they did, but that as soon as that happens, she will return to the United States with her babies, as she is expecting twins.
On the day of the Lefebvres' first hearing, Oliver sees Giselle's bulging belly and realizes that he is sterile. He then attacks his mistress. After this, the session is suspended, and at Oliver's insistence, Giselle visits him in prison, where he apologizes for everything he did to her.
Days later, at the trial, it is proven that the Lefebvres murdered Giselle's parents, and thanks to this, she recovers her laboratory. As she leaves the courthouse, Paulette, Oliver's mistress, threatens her with a gun, telling her that she has lost everything because of her, as Oliver requested a paternity test for his son and has now realized that she lied to him all along.
As she is about to shoot, Nathan steps in, taking the bullet and being seriously wounded, falling into a coma for about two months. When Giselle has the twins, they decide to name them after their mothers.
Suddenly, Nathan wakes up in his bed, realizing that everything he experienced about divorcing Giselle was a dream. Therefore, he decides to change several things he is about to experience, such as sending Iris and Sarah to jail for stealing his perfume and initiating the process against the Lefebvres for the murder of Giselle's parents.Soon after, they discover that Giselle is pregnant, and just like in their dream, they have twin girls whom they name after their mothers.
A few years pass, and Giselle is now one of the best perfumers in France, to the extent that she now has her own perfume brand and also works for different companies, such as Ginevra Marchetti's and Nathan's.
Giselle becomes pregnant again, and this time she has twins, one of whom she names after his father. To conclude the story, several years pass to the point where the protagonists are already grandparents, and Nathan tells his grandchildren the love story between him and Giselle.
