Kim Moon and Han Jisung were inseparable-two halves of the same soul, best friends who shared laughter, dreams, and promises of forever. But life had other plans. Somewhere between growing up and chasing stars, Jisung vanished from Moon's world, leaving her with only memories and an aching silence.
Years later, he shines as a K-pop idol-living the dream Moon always believed in. She supported him through every song, every stage, every success... but only from the shadows. He, on the other hand, never stopped searching for the best friend who slipped through his fingers.
When fate finally pulls them back together, the question is-are they still just "best friends," or did time turn their bond into something deeper?
