When his lover dies in a catastrophic accident, the male lead and his companions abandon their escape plans and scatter across millennia, searching for a way to resurrect what they lost. Centuries pass. The female lead awakens in an ancient world, stripped of her memories but bound by something deeper. When she crosses paths with the king again, neither recognizes the other, yet something undeniable pulls them together. He sees echoes of someone he loved. She feels the weight of a past that isn't hers. What begins as a race against time becomes a meditation on love's persistence across impossible distances. Their reunion isn't a second chance,it's a collision between who they were and who they've become. As fragments of their true past surface, they must confront whether love can survive when everything else has been erased. The question shifts from how to escape Earth to whether they should.
