Shen Qingwan, the legitimate daughter of the Anyuan Marquis Mansion, lost her mother when she was young and suffered a cold reception. She only wanted to break free from the high wall and find freedom. When she was a child, she met Xiao Huaijing, the legitimate son of the Zhenguo General Mansion, at a palace banquet. They made a butterfly pact and the young man promised her a stable and comfortable life. However, the court was in turmoil, the seventh prince Zhao Hengzhi conspired to usurp the throne, and the Anyuan Hou Mansion rebelled. Zhao Hengzhi threatened Shen Qingwan with the lives of his family and Xiao Huaijing, so he was forced to agree to the wedding. On the day of the wedding, Xiao Huaijing rushed into the palace to protect her, but Shen Qingwan died in the snowstorm in order to block the arrows and fragrant jade. In the end, she failed to turn into a butterfly and fly to freedom. However, after Xiao Huaijing put down the rebellion, he kept his lifelong promise and guarded the border alone. For the rest of his life, he would miss that lonely figure longing for freedom.
Purpose: Freedom is the most precious desire of the human heart. Affection and loyalty are worth guarding with all our strength. Even if the shackles of fate are difficult to break and the ending is regrettable, this persistence itself has eternal significance.
