The heroine of this article, named Yu'er, is an illegitimate daughter whose father is unknown. After her mother fell ill and died, she began to live alone. Because everyone knows that Ming Yuer has not had a father since she was a child, so he does not play with her, which also forms her introverted character. In her senior year of high school, she had an adventure. Without her knowledge, a fairy named Chance brought her to an ancient country called Jingguo in order to complete a task. Here, Ming Yuer has her own parents, but her "mother" fell off a cliff and died when she was very young. She was also brought to live in a small mountain village by her nanny, and later she was taken back by her father. Then she started a new life here.
