The series revolves around Robert Cooper, a doctor who was adopted by a Colombian American family, but wants to know who his biological parents are.

Julieta (Zuria Vega) and Robert (Daniel Arenas) have the perfect relationship: they both have jobs, they share their dreams and have agreed to not get married.

For them, the secret lies in two points: communication and the fact that the adoptive family of Robert lives in another country, saving them the problems of dealing with the in-laws.

From there, Robert / Juan Pablo and Julieta will have to learn to live with their in-laws, Blanca (Diana Bracho) and Eugenio (Rafael Inclán), and the sisters-in-law, with all the demands that this entails: a battle between tradition and modernity (including to have the couple get married), a whirlwind of emotions and adventures.

Finally, Julieta has managed to maintain a personal and professional life with balance, next to Robert and their children: the adopted 4-year-old David, and biological daughter Blanquita who is just months old.

This implies new challenges in the lives of Julieta and Robert, including uniting the entire Córcega clan and standing up for yourself at work, and together they will demonstrate that, in spite of the problems of the families they will be able to follow ahead, seeing by their well-being.
