Matheo Fernández is a young man with straight black hair and one of the most powerful beings in his world. He met Ingrid as a child, and over time they became inseparable, falling in love and becoming a couple. However, his life was always marked by a secret: he is the adopted son of Douma, the great enemy Ingrid was destined to face. Everything changed when a soul swap occurred between Ingrid and Douma. The former Ingrid, confused by her new reality, decided to adopt the name Tatiana to distinguish herself from the person she had been. The change affected them both: Tatiana became colder and darker, while Douma began to change for the better. Despite the conflicts, Matheo managed to win Tatiana's heart again, and they began a new relationship. It seemed like a second chance for both of them, but Kae, the new Douma, intervened. He manipulated and drugged Matheo, causing him to be unfaithful to Tatiana with five girls. When she discovered what had happened, the relationship ended. As if that weren't enough, Tatiana also discovered the truth about her past as Ingrid and about Matheo's true identity as the son of her old enemy. What was once a love story between two children who grew up together ended up as a tragedy filled with betrayals, secrets, shattered identities, and wounds that are difficult to heal. The most painful part is that, deep down, Matheo and Ingrid/Tatiana had always been connected since they were little. They weren't two people who met by chance: they were fundamental parts of each other's lives from childhood.
