The modern soul Yu Qianqian traveled through time and became a maid in the Prince of Qi's palace. Everyone in the palace was afraid of the Qi Prince Qi Min, who had been burned and disfigured since childhood, and had a cold and surly temperament. Late at night in late autumn, Yu Qianqian ran into Qi Min, who was suffering from phantom pain due to burns and jumped into a lake. She ignored the dissuasion of others and rescued him. She was the only one who was not afraid of or disliked him. Qi Min was moved by her fresh and open spirit of freedom, and his paranoia imprisoned her beside him. In order to escape from the cage, Yu Qianqian pretended to be obedient and flattery to gain trust, and concealed her pregnancy and set up obstacles to escape. For six years, she relied on modern business ideas to run a large restaurant in Jiangnan and lived a stable life. Finally, she was found by Qi Min, who had been searching for her for six years. When they reunited, they were filled with fear, and a tug of obsession and freedom began.
