I'm Keeping Someone's Home

In an abandoned building in Jiangcheng, there lived an incredibly beautiful young man. I heard that his appearance had not changed in the past fifty years. No one knows that decades ago, he gained eternal life because of a girl. No one knew that decades ago, he witnessed an earth-shattering love story. An immortal who had been with Bai Yueguang for many years and stayed alone for that person for thousands of years. A big demon who stalks and is extremely shameless for love, and will do whatever it takes to get someone. All kinds of gods, all kinds of crazy people, all kinds of bloody love. He guarded the home for the two of them, waiting for them to return to the world from hell.
