it's still a gl even if they didn't end up together. not every story needs a happy ending and she didn't end up…
I'd even argue that the ending implied that they got together. And every story definitely does not need to have a happy ending. The community is always asking for different and soon as we get, even more complaints. There is just no winning.
On a serious note. Please don't mess with their chemistry I beg the powers at be.
