In order to be able to return to the country one day, and to make her beloved King Mu care for her, Concubine Concubine had no choice but to replace a baby girl forcibly carried by the people with her long-dead son. Therefore, "she" became the hostage sent by the Kingdom of Mu to the Kingdom of Lie. It was also destined that "her" fate would be tied to and entangled with three men for the rest of her life.
Lie Ze from the Lie Kingdom was "her" childhood playmate, and many years later he was searching for "her": Mu Yixi, the third prince of the Mu Kingdom, "her" third prince brother in name, was the person she feared the most in her life, and was also the first person to discover the secret of "her" daughter's identity, but inexplicably helped her hide many secrets. Years ago, it was not until the end that "she" discovered that he had already buried a desire for her: Mu Yiyan, the prince of Mu State, the only brother she trusted in Mu State, felt a little affection for him, and finally lost everything he had in order to protect herself.
