serious au this time wow im actually creative during the night???
but au where david gets a wish, and he chooses to undo that demon ritual thing he did where he invites casper the not so friendly fucking ghost and his friends over and he kills his family but he still has his memories of what would have happened if he did
and his family actually begins to go right and his life goes normal, but he meets mao early but she remembers nothing so he convinces her to stay at his home until she's well enough to live on her own cause flames scar n stuff and she's living on the streets and she's practically skin and bones and sadness
and he tells her all that stuff and convinces her its true and so they gotta find that asshole genie or whatever the fuck to get back to "normal" time
and when he does everything is back to normal the fucking end happy ending
