A childhood promise made on a sun-drenched shore in Leyte is the only thing that connects Maya Dela Cruz, a fisherman's daughter, and Eli Ramos, a privileged city boy. Their summers are a secret world of their own, sealed with a vow to always find their way back to each other.

But when tragedy shatters her family's peaceful life, Maya must sacrifice her own dreams of becoming a teacher. She journeys to Manila, trading the open sea for the city's shadows, and endures a grueling existence working in factories and cleaning the offices of the wealthy. For years, she is a ghost, haunted by the memory of a boy she believes has forgotten her—a boy who has grown into a successful architect, living a life she can only watch from an impossible distance.

Years later, their separate worlds collide in the most devastating way imaginable when Super-typhoon Yolanda, one of the most powerful storms in history, obliterates their hometown. Reunited as strangers in the wreckage, they must confront the ghosts of their past and the vast emotional chasm between them.

With all communication lost and their families missing, they embark on a desperate journey back into the heart of the disaster zone. Together, they must navigate the ruins of their shared childhood and find the strength to rebuild a community from the mud. But can a love that was lost to time and tragedy be rebuilt on a foundation of hope?

Until the Sun Comes Back is a sweeping, emotional saga of sacrifice, resilience, and second chances, asking if two people from different worlds can find their way back home—and to each other—after the storm has taken everything.
