so what is this show really about?

A woman who is so meek and unassertive that she actually marries someone she hates?

Or is Emma supposed to be the primary character here, and the series is really about her obsession, hence the title "Sally4Ever"?

Well, except that I don't believe she is actually in love with Sally - she is just a parasite who is unable to pay her own rent.

I was enjoying the show up to a point, but in the end it left a bad taste in my mouth. I hope it's not allowed to continue.
