When she was 10 years old, Xue Jingyao, who was suffering from a strange illness, was betrothed to Yu Qingzhou, the Dragon King of the North Sea, by her parents in a ghost marriage. A jade plaque became the marriage contract that spanned Yin and Yang. At the age of 19, she accidentally triggered the contract and encountered a crisis. The mysterious red-clothed Dragon King appeared to protect her and revealed the thousand-year secret. She was originally the Lord of Nine Netherworld. As various forces compete for the broken souls, Xue Jingyao, while recovering her memory, is faced with the life-and-death decision of "gathering together the broken souls will destroy the Dragon King's soul." This fateful bond that began with a ghostly marriage eventually turned into a two-way journey of thousand-year protection and redemption amid the strangeness and supernatural suspense of the fairy tale.
