Shen Qingci, the legitimate daughter of the general, and childhood sweethearts with the prince Xiao Jingyan, entrusted them with all their affection. But the prince prefers Su Wanrou, and the old feelings gradually fade away. Faced with rumors and despair, Shen Qingci took the initiative to request an order to go to the Northern Desert to get married. In gratitude for her loyalty and bravery, the Holy Emperor canonized her as Princess Jing'an and granted her the honor of being the legitimate princess of the royal family, in exchange for peace between the two countries with a piece of covenant.
The second knock on the jade steps cut off the love of youth and carried up the legacy of father and brother. Ten days later, she bid farewell to the capital and headed towards the windy and sandy sky. In the East Palace, Xiao Jamyan didn't know that the princess he was about to leave for the desert was none other than Shen Qingci, who had been waiting for him silently for many years. When the truth was revealed and the old love was gone, he was left alone in a room full of orchids, full of regrets.
