Grandma told Yu Yan a story: a little fox longed for human life, left home, transformed into a human and came to the human world, but was accidentally injured. The young hunter brought the little fox back and took good care of it.
The little fox fell in love with the hunter, confessed his identity to the hunter and confessed his love to him. Later, they lived happily together.
When Yu Yan grew up, he learned the true ending of the story. The hunter killed the little fox while she was sleeping, skinned her, and presented it to the girl he had loved for a long time. Later, they lived happily together.
