Angelic demon

Hi I'm completely bored and I thought of this random it's 12 AM right now so I'm just gonna head into it (also, none of these characters are mine. Nothing is mine just the idea of the fanfic is)

Angel dust has hidden secrets from his past when he was a human, he doesn't want anything to remind him of the past, but after the extermination day they were they beat Adam Alastor fixed up the hotel, and there was a big party to celebrate after the party nifty is cleaning angel dust is trying his best to help but then nifty needs to run some errands so angel dust cleans up the hotel but then nifty still hasn't returned After two hours so Angel goes looking for nifty

What will happen What trouble has nifty gotten into?
