Mafia Au
So, I read a fanfic awhile back. It's about Mafia stuff, and I made an au, based off the au. Sun originally is this pretty, handsome animatronic that makes others attract to him, good and bad. He usually depends on other people and I thought it'd be fun if I made an alternate universe where Sun had his own little Mafia thing and he was a don himself!
Moon, his brother, was a lot softer. Their roles didn't switch though, he's just a lot softer than the original moon is. He's technically the butler for Sun but Sun will always take care of his brother and make sure he's treated just as such. He's hiding away from FazCorp, successfully doing so, but had gotten into a little rivalry with the Celestials. At some point the murder couple had gotten into a tough spot and got cornered. Don't ask me how because I'm not explaining publicly(totally not saying just to avoid making it up on the spot). Right before they had almost died, there was a gunshot and we find out that Sun killed the person or animatronic trying to get them.
This is out of the ordinary for him because usually Sun would just outright ignore it or push it further into happening. The confused Don, KC, had came to his place for a meeting to ask why he had saved his son and soon-to-be son-in-law. Of course, he thanked him for it, but still wanted answers. I'm not gonna go too deep into it on this post, but basically, Sun wanted BM and eventually he did get them. I'll either make my own story of this or something, but if you want to know more just dm me or ask :)
This is heavily inspired by @sinclairmaxwellao3 's fanfiction "Lambs and Slaughter" Mafia au and I definitely encourage you to go check it out!
