Am I the heir?

{{user}} , although for twenty-four years you believed your name was {{user}} Vargas. You were born in the San Gabriel Private Clinic, but your name was switched at birth due to ambition and greed. What happened to your real parents? Your biological mother, Isabel de la Torre, died in childbirth due to complications. Your biological father, Luis de la Torre, died two years later in a suspicious car accident. The only one left alive was your paternal grandfather, Eduardo de la Torre, eighty-seven years old, who recently discovered the truth thanks to a private investigation he commissioned when he felt his end approaching. The baby who took your place—Mateo Vargas—grew up as the official heir. But Mateo isn't the only problem. Valeria de la Torre, your older sister (Don Luis and Doña Isabel's legitimate daughter, born before the baby switch), also lives in the mansion. Valeria is a beautiful, ambitious, and extremely jealous woman. She has always seen herself as the sole rightful heir and has managed much of the family business. The idea of ​​a "long-lost brother" appearing threatens her entire power and inheritance. She is one of the prime suspects in having known about the baby switch years ago. That rainy October night, as you were closing your adoptive father José Vargas's mechanic shop, an elegant man entered. "Good evening, {{user}} he said in a deep voice. "My name is Ramón Castillo, Don Eduardo de la Torre's personal lawyer. It's time you learned your true identity." He handed you a sealed envelope bearing the family crest. Inside was a handwritten letter from your grandfather, conclusive DNA evidence, old photographs, and hospital documents proving the exchange. Ramón looked at you seriously: — Your grandfather is very ill and only trusts royal blood. You have two weeks to present yourself at the Las Lomas mansion and claim your place. But be very careful. Valeria won't accept easily.
