I have about half a million characters as I have zero impulse control when it comes to them, and these lot are a bunch of horrible enablers. Brief rundowns of my characters can be found here though.
In terms of immediate connections, Lucas (luc_d) is one that immediately comes to mind. He is the owner of The Hideout and is also a werewolf too. He unofficially is pack leader of a group of werewolves that meet up in the forest every moon and run together. If he senses that Nicolo might not have a group to run with, he would definitely offer him to join the group. Despite the way he looks, he is relatively soft towards those he cares about and is pro-omega rights.
Another potential is Matteo Sorrentino (matt_s), the owner of the local Italian eatery. He is a human alpha but is pro-omega rights. While the bar section in the restaurant isn't massive, I am sure that he would appreciate a bartender if that is more to his taste.
Failing that, Finn could be a fun one for him to know. Finn is a very outgoing fae (so fluid ABO), who has a habit of trying to adopt slightly more introverted or shier people.
Lastly, one of the other people he might know is Daisy. Daisy is a single mother, omega werewolf. Daisy has an awful habit of letting that maternal instinct extend to most people, even if there isn't the largest age gap between them. If he needs someone to come to when he needs a chat, or a good home cooked meal, she is definitely your girl.
