Having lost everything in her life, Yao Liang Liang’s flat 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, by coincidence, bears a striking resemblance to her favourite idol, Wang Zheng. As 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 – a role no one has ever seen before the arranged marriage takes place. But whilst they help each other to get what they want, they also fall in love.
