In a kingdom where tradition ruled and love was dictated by duty, Crown Prince Fourth Nattawat had long resigned himself to a life devoid of affection. Cold, calculating, and distant, he thrived in the shadows, his heart closed off to anything that threatened his carefully built walls. The moon was his only companion, and the throne was his destiny. But fate had other plans. On a night meant to secure a future bride, his eyes fell not on a princess, but on a mysterious young man named Gemini Norawit. Gemini, poor and unremarkable in the eyes of the court, radiated a warmth and light that pulled at something deep within Fourth's soul. In a world where appearances meant everything, Fourth was inexplicably drawn to the one person who seemed to defy all expectations. Unbeknownst to Fourth, Gemini harbored a secret-a truth buried in the sands of time. He was from a world far ahead, from a future that did not belong in this era. Sent to change the course of the cold prince's life, Gemini's arrival was no accident. But as their paths intertwined and their hearts grew closer, the line between duty and desire began to blur. Now, with a kingdom's fate in the balance, and time slipping through their fingers, the two must confront the impossible choice between love and legacy. For the bond they share will either save the crown... or destroy it.
