The carefully guarded secret within the walls of "La Promesa" has finally been exposed, sending ripples of scandal through the esteemed estate. In a development that promises to reshape the dynamics of the Buenaventura family and their associates, it has been definitively revealed that Máximo de Buenaventura is the biological father of Ángela. This revelation, now public knowledge, has ignited an immediate and fervent investigation into the individual responsible for leaking such explosive information, an act poised to trigger significant repercussions.

The immediate aftermath of the disclosure has seen a stark contrast in reactions from the involved parties. Máximo, the Duke of Buenaventura, received the news with a disquieting coolness, instructing his trusted staff member, Tomasa, to refrain from any attempts at denial. This stoic response stands in sharp opposition to that of Ángela, who has expressed profound anger and dismay. Her frustration stems from her recent agreement to allow the Duke to remain at the palace with the tentative hope of gradually building a relationship, a prospect now seemingly jeopardized by the premature public revelation of their connection. The timing of this exposé, she feels, has irrevocably undermined any chance of approaching their newfound familial link with the necessary calm and measured consideration.

Further details concerning the unfolding drama and its broader context within "La Promesa" can be found in the weekly preview of the series, covering the period from August 24th to August 28th, 2026.

The weight of this revelation has fallen heavily on Ángela, Curro, and Leocadia, who have swiftly coalesced around a singular suspect: Lorenzo de la Mata. Their collective conviction is that the Captain has identified the Duke’s paternity as an opportune moment to inflict damage upon Máximo, thereby securing personal advantage from the ensuing turmoil. The veracity of their suspicions remains to be definitively established, but the united front presented by these three individuals underscores the depth of their conviction.

The Disappearance of Simona and Candela Adds to the Palace’s Woes

Compounding the familial scandal, the estate of "La Promesa" awoke to another unsettling development: the unexplained absence of its two principal cooks, Simona and Candela. Their departure, reportedly driven by an inability to endure Julio’s continued mistreatment, has left the household in a state of significant disarray. The immediate impact was felt in the breakfast service, with Teresa forced to improvise a rudimentary bread topping, while Cristóbal dispatched an urgent order to the local tavern for sustenance, all while scrambling to devise a more sustainable solution to the staffing crisis.

Leocadia, quick to assign blame, pointed the finger at the majordomo for the ensuing chaos. However, Cristóbal reminded her of his prior requests for assistance, emphasizing that his authority does not extend to the Duke’s personal staff, thus shifting the locus of responsibility. The exodus of Simona and Candela has also exposed a growing schism among the estate’s owners, who are now confronting the tangible consequences of a protracted and escalating conflict within the domestic staff, a situation that has been allowed to fester for an unacceptably long period.

Manuel, Julieta, and Ciro Return Laden with Secrets

The return of Manuel, Julieta, and Ciro to the palace marks the end of a period during which each individual has navigated a distinct and often clandestine reality. The common thread binding their reappearance is the presence of significant undisclosed information.

Ciro, in particular, has returned with a palpable sense of accomplishment. His recent endeavors have culminated in the successful sale of the manual to a substantial number of companies he engaged with. Lorenzo, impressed by Ciro’s business acumen, has actively encouraged him to pursue even more ambitious goals. The Captain has proposed an expansion of the manufacturing licenses for the engine, a move he anticipates Manuel will oppose. Nevertheless, Lorenzo perceives that Ciro’s influence within the company is steadily increasing, granting him greater latitude to implement his strategic decisions.

Meanwhile, Julieta is maintaining her own carefully constructed deception. She has assured Ciro that her recent absence was dedicated to visiting her mother. In reality, she spent this time in the company of Manuel. A subtle yet potentially incriminating detail, however, threatens to betray her narrative: she continues to wear the red ribbon that Manuel gifted her during their clandestine rendezvous.

Upon their return to the hangar, Julieta succumbed to emotional distress in Manuel’s presence. Following the shared intimacy and happiness they experienced away from the prying eyes of others, she found herself unable to articulate her feelings when Manuel gently inquired if she regretted their time together. This unspoken emotional complexity suggests a deep internal conflict for Julieta.

Curro Asserts His Authority, Refusing Further Humiliation from Ciro

Ciro is also confronted with a markedly transformed Curro upon his return. The young man, no longer willing to endure Ciro’s customary dismissiveness, has decided to assert his newfound standing. Having been officially recognized as the Count of Linaja, Curro has unequivocally declared his intention to cease accepting further humiliation. The King’s ratification of his title has irrevocably altered his position within the social hierarchy, and Curro is now beginning to assume the responsibilities and assert the authority that accompany his elevated status. This shift in power dynamics is likely to create new tensions between him and Ciro.

María’s Heart Yearns for Samuel

Within the domestic staff, Pía has once again engaged María Fernández in a candid discussion regarding her emotional landscape. Pía has urged María to confront and resolve a decision that has become increasingly pressing. When María allows herself to contemplate her deepest desires without external influence, a clear answer emerges: if granted the freedom to choose, her heart’s inclination is to depart with Samuel. This heartfelt confession reintroduces a significant element of doubt into her ongoing relationship with Carlo and serves as a powerful affirmation that her recent kiss with the priest was far more than a fleeting, isolated incident.

Concurrently, Jacobo continues to conceal the true reasons behind his estrangement from Martina and Adriano. He misleads Lorenzo when the Captain attempts to ascertain the source of his distress. However, in private, Jacobo has conveyed a resolute warning: he has no intention of perpetuating the secret of their betrayal indefinitely. Martina and Adriano, aware of their limited ability to influence Jacobo’s decisions, acknowledge that they must now wait and brace themselves for the inevitable consequences when Jacobo decides to publicly disclose their relationship.

The Lingering Question: Who Leaked Máximo’s Paternity?

The public dissemination of Máximo and Leocadia’s paternity story has introduced a new layer of intrigue, a question that may prove as significant as the scandal itself. The information was confined to a select circle of individuals within the palace, strongly suggesting a deliberate act of leakage by an insider.

Ángela, Curro, and Leocadia have unanimously directed their suspicions toward Lorenzo. His established awareness of the potential value of such information makes him a prime candidate. However, at this juncture, no concrete evidence has emerged to definitively confirm the Captain’s culpability. The investigation into the source of the leak is expected to become a central narrative arc in the coming episodes.
