Shen Weiwan is the most inconspicuous concubine in the Prime Minister's Palace, but she has a talent that she has never forgotten. She was framed by her aunt and forced to enter the palace on her aunt's behalf. On the night before entering the palace, she bumped into the demoted champion Xie Jingci, and the two reached a contract: she would help him return to the court, and he would help her establish herself in the harem. Step by step in the palace, she was startled. She used her genius mind to uncover conspiracies, fight with concubines, and transformed from an abandoned son into a woman whom the emperor relied on. Xie Jingci paved the way for her with his talents and strategies, but he became sincere in their relationship day and night. When the contract expires, the calculations and sincerity within the palace wall are intertwined. Will they go their separate ways, or will they work together to break through the shackles of the palace wall?
