As a talented new painter, Zhou Qingfan is known as a genius rarely seen in a century. He was invited to paint a castle for Liu Yu, a young lady who had lived here since she was a child. However, as the two people gradually get along with each other, they develop feelings for each other.
However, after she entered the castle, she would always receive letters from unknown sources. Each letter predicted that things would happen accurately. Later, Zhou Qingfan realized that the truth seemed to be hidden under the magnificent castle.
Liu Yu, as a young lady who grew up in the castle, shows that she has no concern for worldly matters and is as innocent and pure as a blank sheet of paper. However, privately, he is extremely possessive and will not give up until the goal is achieved regardless of the price.
The two were separated for ten years. From the age of fifteen to twenty-five, Liu Yu seemed to get rid of the image of a good girl and transformed into a charming fox, waiting for Zhou Qingfan to be arrested.
Purpose: redeem each other, explore the truth, and break free from prison
