El perro del hortelano

Diana is the Countess of Belflor, a woman with considerable influence, but she is not free to love whomever she desires, as she must choose someone of her own standing, and she desires Teodoro, her secretary. Although willing to relinquish her own desires out of obligation, like the dog in the manger, neither eating nor letting others eat, she will interfere in the secretary's affairs to prevent his relationships with other ladies.
