LOS HILOS DEL PASADO

After being forced to leave her daughter in a group home and ending up hospitalized, Carolina rushed from the clinic in search of her little girl. Unfortunately for her, she received devastating news that made her vow never to touch her heart with anyone. With a painful past, Cristina grew up in a foster home where she dreamed of becoming a famous model and working for the renowned Carolina Guillén. During the presentation of Carolina's new clothing line, Carlos had the opportunity to speak with a prominent businesswoman. When he broke the news to his mother that her designs would be available in a prominent New York store, she was overjoyed. Moments before a benefit for the foster home where Cristina grew up, Carlos had a moment of confusion filled with love. Carolina's son thinks the young woman is the new model they've been waiting for.

While Cristina was desperately searching for a bouquet of white flowers for Carolina, Manuel mistook her for a saleswoman. The young woman corrected him and, thanks to her charisma, won the music producer's affection. Desperate to arrive with the bouquet she had ordered for Carolina's event, Cristina arrived excitedly before the prestigious designer. However, she behaved rudely and offensively toward her great admirer. After the heated encounter with Carolina, in which she felt offended, Cristina expressed her deep disappointment. Now, the admiration she felt for the designer had turned to sadness. After losing her purse, Cristina received an unexpected visit at her home from Manuel, who delivered it to her. Upon learning that Carolina had been rude to her, the producer offered the young woman another chance to meet his wife.

After the incident with Carolina, Cristina was deeply disappointed in her. However, Manuel made it his mission to convince her that his wife was different and give her the opportunity to truly get to know her. Amid the launch of her new clothing line, Carolina contacted the detective she'd hired to find her lost daughter in Europe. However, the designer didn't receive good news. Thanks to Cristina and Marisol, Lorena attended the major music event organized by Manuel. Upon seeing the producer in person, the young woman was enchanted and made that clear from the very first moment. Despite Manuel explaining the importance of the music event he was presenting, Carolina completely forgot. Upset with her husband, the designer arrived late to the event and discovered Manuel's great disappointment.

Deeply hurt by the feeling that Carolina was not interested in his affairs, Manuel expressed his disappointment. The next day, the music producer seemed cold and distant with his wife. At Manuel's request, Cristina went to Carolina's house to get to know her better. She told her personally about her big dream of becoming a model, but only received a painful response. Wanting to make amends for her mistakes, Carolina waited in her room for Manuel to spend the night together. However, a phone call from Lorena interrupted the moment, arousing suspicion and jealousy. Saddened by Carolina's treatment, Cristina left the office devastated. Unexpectedly, Carlos appeared to offer his support, as the flame of love began to rekindle.

Amid Carolina's arduous preparation for Cristina to become a model, the young woman made it clear to the designer that she had no family, as she was an orphan. After many years without seeing her since she was a child, Salvador was delighted to meet Cristina again. Unaware that they shared blood, the two shared what had happened in their lives. After the unexpected encounters he had with Cristina, Carlos can't stop thinking about her. Carolina's stepson feels a special connection with the young woman and longs to see her again. Upon finding her daughter at home, in her boyfriend's arms, Carolina exploded with fury. Faced with the designer's reaction, Manuel demanded to know the reason, but she didn't dare reveal the pain she felt for the girl she had abandoned in the past.

Charmed by Ricardo's presence, Marisol accepted her mother's proposal to go to the movies. However, the paramedic's mood plummeted, and he chose not to go. Excited about Lorena's transformation, Cristina arrived for another day of modeling preparation. However, Carolina was furious upon seeing her altered appearance and, in the face of yet another argument, slapped her. Besides the problems at home, Carolina couldn't help but feel sad about the pain of the past. The designer also remembered the terrible damage Ramiro had caused her life. Devastated by her daughter's absence and the problems at home, Carolina went to church to vent, unaware that Salvador was the priest.

Carolina explains the agency's rules to Cristina, but Carlos's unexpected arrival interrupts the conversation, and Cristina discovers he is Carolina's son. Upon learning of Cristina's dismissal, Carolina goes to her house to convince her that she is making a grave mistake and to show that she is the person capable of driving her to achieve her goals. Due to the mistreatment she has received, Cristina is determined to confront Carolina and resign. Carlos invites Cristina to a restaurant for their first date, where they will prepare the food themselves. Together, they create a romantic moment.

Carolina introduces Carlos to the new model she's hired, which is a huge surprise for Cristina and Carlos. After discovering that Carlos is Carolina's son, Cristina asks them to end their friendship and any previous relationship to avoid future problems at work. After a long time, Tamara returns to Carlos's life. His old relationship will once again put his life at risk, leading him to a major crossroads. After Omar's dinner with Romina's family, Ramiro wants to know how long it will be before he can show up at Carolina's house, as his goal is to see her in person.

Carolina is overjoyed at Tamara's return to Mexico and hopes she will be reunited with her son, Carlos. Carlos meets with Tamara to end their relationship, believing it ended the moment she decided to leave Mexico. Manuel is intrigued by Lorena's intentions, who showed up at the exhibition to greet Carolina with great enthusiasm. María Luisa appears in Carolina's office to ask her to stay away from her son, but this time Carolina is not intimidated by his words.

Carolina, after the intense conversation she had with María Luisa, is more determined than ever to find her daughter. After Carolina's revelation to María Luisa, she launches a private investigation to find out if it's true that her granddaughter is estranged from her, as Carolina claimed. Manuel is determined to give Carolina the space she needs, convinced that this will be the best thing for their relationship. Carlos can't stand the distance Cristina has imposed on their relationship and is now determined to show her that they belong together.

Tamara insists on continuing her relationship with Carlos, even though he has made it clear he no longer wants to, despite his firm comments on the matter. Manuel explodes with fury at Carolina for prioritizing work over her family, demanding that she find balance in her life. Father Salvador discovers that Cristina's boss is Carolina Guillén and is shocked by Cristina's description of her, describing her as a very harsh person. Despite Tamara's efforts to maintain Carlos's love, she appears to harbor a secret connection with Leonardo, admitting that their past experiences led her to decide to leave Mexico.
