Su Jinli, the most talented girl in the capital, was betrayed by her best friend Liu Yingying, whom she regarded as a biological sister, and took away her childhood sweetheart fiancé. Overnight, Su Jinli went from being the proud daughter of heaven to the laughing stock of the whole capital, and became a miserable comparison to Liu Yingying's "come from behind and win true love". Under pressure from her family and ridiculed by everyone, Su Jinli made a shocking decision - to marry Xie Wu'an, the violent and bloodthirsty young master of the Zhenbei Palace who was rumored to have injured his leg on the battlefield and was the archenemy of her fiancé's family.
After her marriage, Su Jinli put away her innocence and relied on her top-notch brains and skills to fight against her aunt, her husband, and her inner ghosts in the deep palace compound, and managed the crisis-ridden palace in order, which amazed everyone. And her "disabled" husband Xie Wu'an gradually shed his pretense of self-restraint and courtesy. In fact, his leg injury was fake and his hibernation was real, just to uncover the traitor in the family and the court. The two "allies" who originally cooperated gradually became sincere as they joined forces to fight against external conspiracies and smashed the schemes of their best friend and ex. From respecting each other like "ice" to being exclusive to each other, Su Jinli not only took back everything that belonged to her, but also worked with her possessive husband to defeat political opponents, expose treasonous plots, and finally stood at the pinnacle of power.
