Amarte así is a sentimental comedy or melodrama. As a teenager in Mexico, Nacho (Mauricio Ochmann) discovered that he could seduce girls by giving them gold rings. With his buddy Lucho, Nacho fornicated with many, many girls, and then never went out with them again. Sometimes Lucho "helped" Nacho by putting a date rape drug in the girl's drink, though Nacho was not aware of this. Being from a rich family, when Nacho finished high school, he went to Los Angeles to study medicine, not knowing that on his last night in Mexico he had impregnated Margarita (Litzy). Lucho had actually drugged both Nacho and Margarita, leading to lack of inhibition and fornication. In the morning Margarita woke up naked and abandoned. She could not find Nacho.
Margarita had been permanently enamored by Nacho the night that she met him, but she also hated him for having impregnated her and abandoned her. She thought that he had drugged her, but actually neither she nor Nacho remembered the fornication, though she had constructed mental images of herself being raped.
Through Lucho, Nacho's brother Francisco (Roberto Mateos) offered money to Margarita to pay for killing Margarita's unborn baby. But Margarita refused. Thus while Nacho was spending six years in LA, Margarita at the age of 15 gave birth to Frijolito.
All the above is shown by flashbacks, and what happened in the past is only revealed in bits and pieces here and there during the telenovela. The telenovela begins with Nacho returning to Esperanza, Mexico, not remembering Margarita nor knowing that he has a son. Since Margarita lies like Pinocchio (nickname Doña Mentiras), the truth comes out only slowly. Generally Nacho is the last to know, which adds to the comedy.
The plot is cyclical. It follows this pattern: 1) Margarita is in a snit vs. Nacho, 2) Margarita melts, 3) love blazes between the two, 4) Margarita gets angry again vs. Nacho and goes back into a snit vs. him. There are about 9 cycles of this. All of
