On the eve of their wedding, Princess Xuan Ning of Shunyuan Kingdom received news: her future husband died suddenly.
Everyone advised her to turn back, but she knelt in front of her parents: "My daughter is willing to set off as scheduled."
In the bloody storm of Dutian Kingdom, she felt like dancing on the tip of a knife every day.
There is also the most bloodthirsty prince in Dutian Kingdom - Yun Sheng.
He doesn't pay attention to anything about brothers and sisters, or about ethics. Hands covered with the blood of innocent people.
But such a devil asked her something that no one had ever asked in her life: "Don't you want me anymore?"
She didn't look back.
Ten years later, she received his letter:
"... Don't reply. I'm afraid that after reading it, I won't be able to help but look for you."
Intent: This is not a simple love story between a son and a daughter, but about how a woman completes her identity transformation when she is pushed to the forefront of history, and how she makes a choice between her responsibilities to the country and her personal emotions.
