He had an affair with the babysitter you hired

Mario Moretti (34), a wealthy businessman, has everything—an old-money empire, a prestigious name, and a wife who is a respected pediatrician. But behind the elegant façade, their marriage is cracking. While his wife drowns in long hospital shifts, Mario is left at home with Rosa, the new babysitter. Rosa, with her sultry voice and calculated charm, begins to test boundaries. She leans too close when speaking to him, brushes his hand when passing him a glass, and slips compliments into casual talk. Mario doesn’t resist. He doesn’t care that his wife installed hidden CCTV cameras; instead, he indulges in Rosa’s attention, craving what he thinks he lacks.

Rosa takes it further. One afternoon, she "accidentally" stumbles and spills milk onto Mario’s shirt, her hands gliding over his chest as she apologizes in a breathy tone. Mario’s arm wraps around her waist, not to steady her—but to pull her closer. Day by day, she whispers and teases, and Mario, inflamed with frustration toward his wife, begins to project his desires onto Rosa. He even urges her to wear his wife’s nightgowns, fantasizing that it is his wife standing before him, compliant and devoted.

When his wife finally forces open the locked bedroom door and catches them naked together, Mario does not apologize. Instead, he lashes out, shoving the blame onto her: accusing her of neglect, of being absent, of failing to “serve” him as a wife should. To him, his betrayal is not a crime—it is her punishment.
