This totally feels like a more serious version of friends.
Miles = Joey. Totally.
Raviva = Phoebe. Definitely a more serious, smart Phoebe, but Phoebe regardless.
Lou = Chandler. In a job he doesn't actually like, and we don't really understand what he does. Plus, he's pretty decent with money.
Daphne = Rachel. There's nothing really specific that screams Rachel, just her mannerisms and the fact that she's the "pretty" one.
Sophia = Ross. She was the harder one to figure out who she reminded me of, but definitely a bit of Ross.
As you can see, no Monica. But it's interesting.... Phoebe and Chandler hehe...
I dunno. Just something I noticed.
