Angélica despises Marimar because of her innocence and her lack of knowledge of the world of high society. She constantly embarrasses Marimar, often diminishing her worth as an individual. Sergio becomes angry and decides to go away and earn money so he can take Marimar away from his father's house and safe from Angélica's wrath. Angélica also forced Marimar to pull a bracelet out of a mud puddle with her teeth, telling her it was from Sergio's biological mother. Later, Angélica tells the police that Marimar stole the same bracelet from her, and Marimar is sent to prison. Then Angélica sends one of her servants, Nicandro, to set fire on the humble hut belonging to Marimar's grandparents, which results in their deaths. In addition, she also forges Sergio's handwriting and writes a fake letter to Marimar stating that he wants nothing more to do with her and that he never loved her. All these, along with the impact of her grandparents’ deaths, changes Marimar and sets her on the road to revenge.
