He was named Prince Ning, but because of his ambition, he made a mistake that he could never redeem himself in his life. They fell in love, and she disobeyed the devil for him, violated the rules of heaven, changed her fate against heaven, and died without a burial place; he finally ascended the throne, but he gave up his dragon robe for her and shaved his head, just to atone for her life's sins and exchange for seeing her again in rebirth. When they meet again, her sins are redeemed and he grows old. There are more than just years and years between them.
