The Lazy Taoist of the Fox Demon

There are demons in the world, and demons will fall in love with people. Demons live for tens of millions of years, and humans have a limited life span. When people die, demons live. People will be reincarnated, but after reincarnation, they will not remember the love of their previous lives. If the demon is infatuated, he will go to the fox demon to "purchase" a service that allows the reincarnated person to recall the love of his previous life... When a lazy protagonist who does have regrets about change appears, how will the world of the fox demon change?
