Hayley Smith. She is in a place where she has a hard time moving out due to the rising cost of living. She puts up with her conservative dad's nonsense. I can really empathize with that because I was told time and time again that I was a failure by a conservative dad that was out of touch with the reality of how expensive everything is.
I wanted to say Klaus, but also he seems to be doing alright (usually) and he's kind of a dick. I feel that way about a lot of the characters though.
I do feel a bit bad for Billy, but he really seems to make the most of his situation and lives his life.
