Ten years ago, the imperial palace was shattered when Ruanlin, beloved son of King Zhongfu, was stolen away in the dead of night by a dark cult. They spirited the young prince to an ancient temple, where they planned to sacrifice the boy to the demon king, Varis.
Despite his efforts to save his son, King Zhongfu arrived too late. Sensing an opportunity, Varis offered a bargain: he would restore the prince to life and allow him to grow up in the mortal realm, but on his eighteenth birthday, the demon would return, and Ruanlin would be bound eternally to Varis as his bride. With no choice but to accept, King Zhongfu sealed his son's fate.
Now, one month after Prince Ruanlin's eighteenth birthday, the shadow of that terrible promise looms. Soon, Varis will come to collect his due... and Ruanlin will have no choice but to accept his destiny.
