*slides into your dms* Love & Monsters you say??
This AU was inspired by the movie "Love & Monsters".
It starts in a post apocalyptic setting similar to that of the movie (blowing up a comet caused a bunch of animals to rapidly mutate into monsters). Entirely by accident, Steve wound up being with his girlfriend Nancy's little brother and his friends when the apocalypse happened, and the group of them have survived thus far by hiding out in a (modified to fit the setting) castle byers, and being very very cautious so as to have to fight the monsters as little as possible.
But Will got hurt, some time back, and despite their best efforts to treat the injury, he's got an infection now. They need medicine they do not have at castle byers, and Steve's already scoured the area within a day's walk or so of there looking for medicine and other important supplies and been unable to find what they need.
Steve can't leave the kids for more than a day at a time, so they're all going to have to go out together to try and find medicine for Will, a better place to set up (Castle Byers is compromised and increasingly unsafe), and other survivors (if there even is any).
On their journey they're going to encounter Billy & Max, who had only just moved to Hawkins mere days before the apocalypse started, and a lot of other characters. Billy & Max are going to somewhat take on the roles that Clyde & Minnow have in the movie, having survived together in a very different way than Steve and the party have.
Dart gets to have a part in this story too, and is a monster that Dustin befriends.
Also in this AU Chrissy and Eddie find Holly by herself and out in the open shortly after the apocalypse and have been taking care of her together since then.
Eventually the (now bigger) group makes their way to Murray's bunker (which has also been modified for setting) and get to reunite with some of their lost loved ones. Steve's been feeling guilty this whole time for developing feelings for Billy since he and nancy were still together when the apocalypse started and he doesn't know if she's still alive, but when they arrive at the bunker Nancy has already moved on (assuming Steve died) so, after feeling a bit wrecked that she assumed he'd die and also that she moved on so quickly, he finally lets himself acknowledge the feelings he's developed for Billy and they get their happily ever after.
