Please recommend a novel about humans and foxes. I forgot the specific name.

The male fox went to repay his kindness. Then, the male protagonist found a woman who looked very similar to the fox to be his wife. Later, the fox destroyed his cultivation in order to save the male protagonist. A thousand years later, the male protagonist and his classmates were walking on the road to discuss the exam situation. On the other side, they saw a young man in white who smiled at him. The wind blew the messy hair on the young man's forehead, and there was a mark on his forehead... I only remember the end
It was as if the male protagonist had reincarnated seven times. Back then, the male protagonist had put the fox in the basket behind him and carried him on his journey.

Perhaps it was the book," The Boy in Skinny Cloth," which told the story of a 20-year-old boy who was attracted to a fox and a woman.
