After losing everything in her life, Yao Liang Liang’s apartment merges with that of the emperor of an ancient kingdom, allowing them to travel between the two worlds. There, she meets a future emperor who, coincidentally, resembles her favorite idol, Wang Zheng. Since Yao Liang Liang appears at a crucial moment for the king, the two strike a deal. He will give her the money she needs, and she will be his betrothed—whom no one has ever seen before the arranged marriage. But as they help each other get what they want, they also fall in love.
