“Promise” became the standout success of its season on La 1. In January, public television rolled out a new diary edit for its desktop slot, steadily boosting viewership each week until Antena 3 and Telecinco submitted competitive bids. This Tuesday the Bambú-produced series reached its 100th episode.
Today’s episode centers on Pia and Gregorio’s wedding, an event that has kept viewers on edge for days. Yet the union, arranged by the will of the marquises, threatens to cast a pall over the celebration. TVE releases details on the development. Additionally, Jana returns to La Promesa after her stint at the Dukes of Los Infantes’ residence. Her difficult circumstances may push Manuel closer to the edge of his patience.
Since its debut, The Promise has averaged 990,000 viewers with a 10.3% share on linear TV. In May, the series climbed to an average of 11.7%, nearly three points higher than in January. On May 10 the show reached a daily peak of 1,188,000 viewers and a 12.6% share. When deferred viewing is included, the average climbs to 1,230,000 viewers and a 12.1% share.

Created by Josep Cister Rubio, The Promise features a cast led by Ana Garcés, Arturo Sancho, Eva Martín, Joaquín Climent, María Castro, Antonio Velázquez, Andrea del Río, Manuel Regueiro, Carmen Flores, Teresa Quintero, Enrique Fortún, Carmen Asecas, Sara Sánchez, Paula Losada, Marga, Xavi Lock, and Amparo Piñero.
The production spans two sets totaling 3,000 square meters, with meticulous recreations of interiors from an early 20th‑century noble estate. Outside the Rincón Palace stands a grand late 19th‑century building in Aldea del Fresno, along with the El Jaral de la Mira estate near Madrid, all serving as the backdrop for the drama.
Viewers follow Jana’s story each afternoon. A young woman of humble origins arrives at the Marquises of Luján’s estate to probe the murder of her mother fifteen years earlier and to locate her missing brother. Her quest for revenge soon intertwines with a growing, complicated romance with Manuel, the heir to the Marqueses.
Across these 100 episodes, audiences are drawn not only by the class divide but also by Jana’s evolving research and her impossible love. The series also follows the marriage between the beloved Manuel and Jimena, the heiress to the Dukes of the Infantes. Alongside such serious incidents as the murders of Tomás and the Baron of Linaja, viewers witness power dynamics among nobles and their staff, and the shifting loyalties within a sprawling household.
