The plot follows the love story of Martín Quesada, an affluent businessman, and Esperanza Muñoz, a struggling female boxer who becomes his personal assistant.
The telenovela was produced by Pol-ka based on a premise by Adrián Suar, which he formulated nearly six months before the show's premiere, after discussion with his partner Javier Blanco y Tevah.
[2] The premise involves a rich businessman and former Formula 1 racing driver who falls in love with a poor woman looking for work in his emporium.
The program was directed by Daniel De Felippo and Rodolfo Antúnez and produced by César Markus González.
The relationship between the two was more than professional; Facundo Arana had spontaneously been offered a guest appearance on the Russian series A ritmo de tango starring Oreiro.
[3] Oreiro delayed filming proposals in Israel, Spain, and Uruguay, and the recording of her fourth music album to join the project.
Her adoptive mother Nieves lives with Enrique "Quique" Ferreti, her natural son and Esperanza's childhood boyfriend.
The writers drafted Quique's general outlines; Belloso defined most of his personality, including the relationship with Esperanza—which is halfway between engagement and brotherhood—and his Oedipus complex with his mother.
This injury complicates her economic situation, as her boxing provides the only income for her adoptive family, namely Quique and his mother, Maria de las Nieves.
Martín Quesada, the president of the company, sees Esperanza crying in the street and hires her as his personal assistant.
After the breakup with Esperanza, Martín resumes his romance with Constanza and eventually proposes marriage to her, in order to improve his chances of winning custody of the three siblings.
The judge, who thought that Esperanza was a bad influence on the children, gives the adoption to Constanza instead of Martín, forcing him to marry her.
Due to the efforts of Martín's cousin Miguel, the unscrupulous lawyer "Falucho", and Constanza, Martin gradually loses his fortune, his business, and his house.
The program was directed by Daniel De Felippo and Rodolfo Antúnez, and produced by César Markus González.
[1] The choice of Martín Quesada's background as a Formula 1 driver required an area with a large infrastructure to represent realistic races.
Facundo Arana and Natalia Oreiro played their characters in the Veltins-Arena stadium during the Argentina-Serbia and Montenegro match.
[4] They taught Oreiro how to stand and move in the ring and how to make various types of strokes, and she underwent cardiovascular and weight training.
[15] The appearance of actress Leticia Brédice was nominated for the "best cameo in fiction" category at the Martín Fierro Awards; the prize was given to Nora Cárpena.
The hero of the telenovela marries the villain, contrary to the genre's usual convention in which such a wedding is interrupted or canceled at the last moment.
[21] The competitor channel Telefe aired the teen comedy Alma Pirata, which was rescheduled because of its low ratings,[22] and replaced it with the second season of Casados con Hijos.
Facundo Arana received the award for best lead actor in comedy, prevailing over Guillermo Francella, Humberto Tortonese, and Nicolás Vázquez.
Natalia Oreiro won the award for the best lead actress in comedy, prevailing over Florencia Peña, Nancy Duplaá, Carmen Barbieri, and Andrea Bonelli.
Similarly, three of five nominations for supporting comedy actress went to Carla Peterson, Mónica Ayos and Claudia Fontán, but the award went to Érika Rivas of Casados con hijos.
[29] The Clarín newspaper attributes the success of the program to the actors' performances, the subplots, production initiatives, and the original treatment of stories.
[1][30] The work of the supporting cast was also praised, including Carla Peterson,[31] Fabiana Garcia Lago,[32] and Marcelo Mazzarello.
The Mexican version, Un gancho al corazón, starred Danna García, Sebastián Rulli, Laisha Wilkins, and Raul Araiza.
The Polish version, Prosto w serce, starred Anna Mucha, Filip Bobek, and Małgorzata Socha.
