The Flower in His Cursed Garden (Xiao x GN!Reader)

Xiao had faced nothing but karma and cursed energy throughout his life. The only thing he has ever learned was suffering, and thankfully, he learned how to control it. At least he thought he did...until one day the pain became so bad, he couldn't control it and became corrupted once more. However, this time was different, as there could be no way for him to return to reality....at least it was thought so if he hadn't met a particular someone who would change his life in more ways than one.
