A new wave of young adult romance is gaining huge attention online, driven by TikTok fandoms, viral edits, and strong reader communities. Short clips, fan theories, and AI-made posters often turn fictional relationships into full-scale online debates that feel almost real.
This trend has helped romance stories become one of the most reliable genres for streaming platforms. Many companies now invest in best-selling novels that already have active fanbases on social media before filming even begins.
From Wattpad story to global film franchise
The latest project in this space is Your Fault: London, a film based on the Culpables trilogy by Spanish author Mercedes Ron. The original books were first published on Wattpad, where Ron began sharing her stories as a teenager.
The trilogy, which includes Culpa Mía, Culpa Tuya, and Culpa Nuestra, quickly built a strong teenage readership.
Ron wrote the books before turning 20, and they went on to shape a major international franchise.
Cast speaks about intense fan culture
Banks noted that social media plays a major role in the franchise’s success, especially through platforms where fan content spreads quickly and keeps interest alive between releases.
Broome and Banks both said the existing fanbase brings strong expectations, which adds pressure but also helps the project reach wider audiences.
Storyline of Your Fault: London
The film follows Noah, who moves to London after her mother marries a wealthy businessman. She meets her new stepbrother Nick, and a complicated relationship develops between them.
