One More Time Around (Might Do It)

"That was just another fun little quirk of the world-not only was the majority of the population juiced up on magical mojo, but pretty much everyone had a soulmate mark. Sure, a lot of people don't actually find their soulmate-statistical probabilities are a bitch, aren't they?-but it's a time-honored thing. Soulmates are a blessing, the one person the universe has fated to be your perfect complement. Soulmates are to be sought after and cherished-the ending to ever story destined to be of the happily ever after variety. And Stiles doesn't have one. He doesn't have fangs or claws, and he certainly doesn't have a soulmate mark anywhere on his body. He just has himself, his shop, and his cat. If you ask Stiles, that's more than enough."

A futuristic AU where almost everybody has supernatural powers and a soulmate mark, and Stiles has neither of those things.
