The Final Snow

I made a contract with the King of the Underworld: I would go to another world and live as another woman, keeping her "husband" company until the end of her life. In return, he would let me return to life and reunite with my family. But I never expected my "husband" to be a woman. She is the ruler of the Kingdom of Zhongxue, gentle and mild-mannered. And I am the moonlight she holds in the palm of her hand. Reading Guide: 1. First-person narration. The ending is sad before it turns happy; the protagonists don't suffer. 2. This story is entirely fictional. I made it all up.
