According to an inside source, by the early broadcast of the series, the producers didn't like much the on-screen couple made by Betty Monroe and Cristián de la Fuente. Plans were then made to kill Monroe's character in order for Marjorie de Sousa to take over as leading female. Nevertheless, they realized that it would have been too expensive to finalize Monroe, who could have also suited Televisa as she had a contract for the whole series. Besides, she had achieved a greater connection with the audience after shaving her head for playing cancer-ill. The decision was overturned, but by then De Sousa had already been called to play Cristina, with a wide character development.
