Yan Wei, a modern high school senior, suffers an accident and transmigrates into the body of Yan Wei, daughter of the great general Yan Mohan of the ancient Ning Kingdom.
Becoming the daughter of a wealthy family should have been a blessing. But because of her family's influence, she catches the eye of Zhao Ransheng, the third prince of the Dongying Kingdom. Using the prospect of a marriage alliance between the two nations as a pretext, Zhao Ransheng plans to send Yan Wei, who was never meant to marry, away as a diplomatic bride.
Fate takes another turn, and Yan Wei fails to find the happiness she wanted.
For the sake of relations between the two kingdoms, she can only set out for Dongying to marry into its royal family.
But in the end, she discovers that it was all a conspiracy.
That day, she picks up a blade and stabs without hesitation.
Yan Wei: “With this, we're even. Stay away from me from now on.”
Yusheng: “I'm sorry. I started this, so I should be the one to end it.”
