She doesn't go out much, and it's suggested that she never had a boyfriend before, because of her brothers' protectiveness. When she meets Bernando Elizando, she falls in love with him despite their age difference. Bernando lies to her, telling her that he is single and lives with his sister and three nieces, but he also falls in love with her. The Reyes brothers find out about them and they are all furious that she didn't tell them. However, when they learn that Libia is pregnant, they sanction a marriage between their sister and Bernando. Unfortunately, Bernando dies in an accident, leaving Libia devastated and angry because of his lies. Encouraged by a nosy store owner and her sons, she goes to the Elizando mansion to talk to Bernando's widow, Gabriela Elizando (played by veteran actress Kristina Lilley), who humiliates her by calling her a slut and a gold digger in front of everybody. Crying hysterically, she leaves the mansion. Libia then proceeds to kill herself by jumping off a bridge and falling in a lake. When her brothers find out, they are devastated and swear on their sister's tomb that they'll avenge her death. Later on the Reyes brothers meet Ruth Uribe (Ana Lucía Domínguez), a rich girl who looks exactly like Libia. The Reyes brothers are amazed by their resemblance and consider her their adoptive little sister. Ruth represents the symbol the Reyes brothers can still hold to Libia. It is later revealed that Ruth is the Reyes' cousin, explaining Libia and Ruth's resemblance.
