It's multiple stories driven by the same set of events.
Osborne and Harry both have riches to rags stories of varying degrees. Things get progressively worse for the both of them, but Osborne wasn't doing so great to start with.
Kate and Linda have Cinderella stories of varying degrees. They both start off thinking they're getting what they want, things get worse for most of the story, and both end up with basically what they started out trying to get in the end.
I'd love to hear how anyone could argue that it fits any one of these.
