In a world where invisible strings connect soulmates, Jeonghan — a Korean idol with the rare ability to see these strings — has always been haunted by the delicate red thread tied to his pinky. It stretched far beyond borders, never leading to anyone around him. Until one ordinary fan meeting in Seoul.

You, a fan from the Philippines, had never believed in fate — let alone soulmates. To her, meeting Jeonghan was just a once-in-a-lifetime dream come true. But the moment their eyes met, Jeonghan’s heart paused. The red string that had tugged at him his whole life was now glowing, alive — and it ended at her.

She couldn’t see it. He couldn’t ignore it.

And so begins their quiet, complicated story — of fate, of distance, and of a love only one of them knows is written in the stars.
