The franchise began not in a studio boardroom, but on the self-publishing platform Wattpad in 2017. Argentine-Spanish author Mercedes Ron penned Culpa Mía as an obsessive, forbidden story tracing the turbulent collision between seventeen-year-old Noah and her wealthy new stepbrother, Nick. Driven by illicit street racing, underground fight clubs, and intense emotional trauma, the digital uploads garnered over 50 million reads before Penguin Random House acquired the physical rights.
When Prime Video debuted the Spanish film adaptation in June 2023, the production instantly captured the number one non-English streaming slot in more than 190 countries. The film turned lead actors Nicole Wallace and Gabriel Guevara into international sensations almost overnight. Amazon quickly committed to back-to-back production for the two sequels: Your Fault (Culpa Tuya) and Our Fault (Culpa Nuestra). That heavy corporate investment cemented the story as the streaming service's highest-converting young-adult property in European history.
