A great battle leaves the commanding general dead, the Crown Prince's fate unknown, and the court forced to move south.
The Fourth Prince, Feng He, looks exactly like the Crown Prince, Feng Xi. For years, the Empress has forced him to impersonate Feng Xi.
After her elder sister, Qiu Yuying, flees her marriage, Qiu Yuhe is seized and forced to take her place as Crown Princess.
To the north, the formidable Xiaohan threaten the border. To the south, pirates wreak havoc along the coast. In between stands a court full of selfish officials. Faced with an empire on the brink of collapse, everyone can only shake their heads.
To carve out a way to survive, Qiu Yuhe and Feng He form an alliance.
When pirates cause chaos and hang the county magistrate's severed head from the county office sign, the whole court is too afraid to take the post. They choose Qiu Shiyin, a man with neither connections nor ability, as a disposable pawn. To save her father, Qiu Yuhe charges into the imperial palace. Then she leaves her fiancé behind and accompanies her father to take up the post.
When the emperor dies, Feng He takes the throne. The eldest prince refuses to accept it and plans to rebel, while the Xiaohan seek to take advantage of the chaos. Qiu Yuhe goes to the front lines herself to negotiate with the eldest prince. In the end, she persuades him to stand down and drives back the Xiaohan forces.
Feng He is caught in a storm of doubts about the legitimacy of his claim. Qiu Yuhe tells him that his identity doesn't matter. What matters is what he does...
They build weapons, train troops, and promote capable generals to fend off foreign enemies;
They cut redundant positions, clean up officialdom, prioritize the economy, and improve people's lives.
A false Crown Prince and a false Crown Princess pull a nation battered by storms out of the mire and lead it to greatness. Supporting each other every step of the way, they go from youthful beauty to white hair, and create a legendary love story for the ages.
