Chi Yan, a human girl, was haunted by foxes. When camping outside the school, she met a real nine-tailed fox demon, Yin Ran, and was entangled by his ninth tail. To get back his broken tail, Yin Ran needs to grant her a wish, but the girl just wants to get rid of him. So the charming fox looked at her with temptation, "Do you want to make a wish now?"
