Xian Yu is the most honored princess of Miaojiang. After her coming-of-age ceremony, she sets out for the Central Plains with a token of betrothal, seeking the fiance she has never met.
As she climbs up a cliff, she unexpectedly finds a badly wounded man. The jade pendant falls from his arms, fitting perfectly with the betrothal token she carries.
Overjoyed, Xian Yu immediately carries him back to treat his injuries.
The man is aloof in appearance and frail, with an air of illness about him. Xian Yu not only tends to his health with great care, but also takes action to eliminate the assassins pursuing him.
Her heart full of joy, she has already begun planning to have children with him one day.
Until one day, she sees with her own eyes her usually frail fiance wielding his sword with chilling precision, dispatching the assassins.
He wipes the bloodied blade against the crook of his elbow and says in a cold, indifferent voice, "That Miaojiang girl may be stupid, but I can keep her around to use as leverage against my imperial brother."
His words strike like thunder. Only then does Xian Yu realize that not only has she mistaken him for her fiance, but he has been using and manipulating her all along. What unsettles her even more is that she has already fallen for this liar.
But it doesn't matter. Her mother told her that men care most about their pride, and the best revenge is to win them over, then dump them.
While he is still recovering, she secretly drugs him and takes charge of the whole affair, fumbling her way through it. At dawn, she leaves four crooked words behind: "You're not very good," then walks away without a care.
After the new emperor ascends the throne, the first thing he does is surround Miaojiang with troops. As it happens, the princess of Miaojiang is getting married, and the new emperor says ominously that he has come especially to share a cup of celebratory wine.
Xian Yu watches in confusion as he advances step by step, until she is trapped right in front of him. He has always hated Gu insects, but now he bites his tongue and forces her to place a love Gu inside him.
With a click, cold chains snap around their wrists. From then on, neither can escape, no matter how far apart they are.
