what happens when the king of curses; ryomen sukuna, see's the reincarnation of his wife whom died in the heian era?

So basically this is a product of excessive daydreaming, spare time, maybe an obsession and a lot more factors that I'm sure are unhealthy but that's besides the point, I guess I'm supposed to tell you about the book but screw that all you need to know is that it's a demon slayer au I guess but I hope you like it or whatever I just wrote it for myself I'm not expecting anything so let's just roll with it, if your interested then just read it no pressure. Note: the book I got inspiration from is called why tf are demons from demon slayer here @Sombtri
