If it wasn't axed, was it that the writter didn't know how to properly end it and clumsily stumbled about doing it?
Because all this controversy about both of them being a couple felt very weird the whole way through. It was very, very awkward, for a series that had managed to keep a pretty nice pace the whole way through IMO, and there was a very noticeable shift in the feel of it all, and didn't feel all that natural. I can only hope the author manages to learn from this and next time he manages better how to go about ending his work.
Thankfully most stuff before this part went from OK to very good, so it isn't like the story got completely demolished, and this ending just felt weird, instead of unfitting or feeling overly forced. I do believe this kind of ending could have worked, but the execution wasn't the best.
