Ye Qinghuan has been lonely since he was a child. Because of his mother's kindness, he made a marriage contract with Lin Zechuan, hoping to stay together in peace and stability. She unexpectedly foiled the other party's plan after rebirth, only to find out that she was a descendant of King Duan who was living among the people. The Lin family mother and son actually wanted to forge a token so that someone else could go to Beijing to recognize her relatives on her behalf, and also set up a trap to lure her to a dangerous place. Qing Huan was smart and decisive, and took advantage of the plan, leaving behind the counterfeit jade pendant and quietly heading to the capital. With the help of tokens and evidence of life experience, she successfully recognized Prince Duan and his daughter, and the father and daughter worked together to make arrangements for the impostor to expose himself. In the end, Qing Huan returned to Prince Duan's Mansion, regained the warmth of her loved ones, said goodbye to old entanglements, and started a new life of her own.
