Hermanas, un amor compartido

Rebeca and Mónica Olmos are sisters with different personalities who, despite this, always lived united by love, until a mistake changed their lives forever. Aura was born from a one-night stand between Alonso Beristáin and Rebeca. He never knew about Rebeca's pregnancy, since he left to study abroad in Europe; but his father, Silverio, a violent man, did know, and threatened Rebeca with getting rid of the baby if it was born, because he would never allow his son to ruin his life with her. Rebeca accidentally runs over Francisca, Silverio's maid, and he uses this to falsely accuse Rebeca of killing her, paying to have her imprisoned without trial in order to keep her away from Alonso. When Aura is born, Rebeca gives her up to a children's home to prevent her from living in prison and growing up ashamed of her mother. However, Mónica decides to adopt her, sacrificing her own plans to get married, as her fiancé refuses to support her with the child. Rebeca, upon learning that Mónica has adopted Aura, asks her to raise her as if she were her own daughter and never tell her the truth about her origins.^[5]

However, years of imprisonment and remorse change Rebeca, and eighteen years later, after serving her sentence, she is released from prison with the sole purpose of getting Aura back, turning her sister's life upside down and starting a battle between the two of them. At the same time, Alonso tries to divorce Lía, as their relationship deteriorated due Lía's unhealthy jealousy of Azul, their seven-year-old daughter. Rebeca relies on Camilo Cué, nephew of Antonia, her mentor in prison. Ever since Camilo saw Rebeca years ago in prison, when he was doing charity work for the inmates, he was captivated by her and is now determined to make her fall in love with him.^[5]

Mónica starts working at the publishing house Azul Profundo, owned and directed by Alonso. They meet there and, unaware of the bond that unites them through Aura, end up falling in love. When Rebeca finds out, she becomes enraged and rebukes her sister for being with the man who ruined her life. Everything becomes more complicated when Alonso finds out that Aura is his daughter and Lía sets out to make their lives miserable, losing her sanity more and more and allying herself with Silverio to get rid of Mónica and hurt Aura by any means possible. These circumstances, coupled with Rebeca's approach to Aura, making her believe that she is her aunt, make it increasingly difficult to sustain the big lie that the girl has been living and that threatens to fall apart at any moment.^[5]
