Enzo

Finally adding him to the site...

Enzo is a human, who works as a Delivery Driver, who was born in Mexico but lived in America most of his life before eventually ending up in Italy where the others are. He's a romantic, and a playboy, heavily interested in flirting with other men even when they aren't interested.
He also smokes during his breaks.

Sure, while he's too busy being distracted by his co-workers to focus on his work, he still doesn't get fired because his boss needs the employees.
That means he can stay where he works, even when he isn't that great at matching the others.
