True, I know that and as I said, they could simply be themed that way to make them like a matching set of enemies or maybe even just friends and she somehow shifts him to their side. I mean, they can at least relate to each other in some way. But who cares about the crazy shippers of tumblr? No fandom has any right to change a series to their liking and no writer or owner of a series should feel they have any obligation to because, no matter what, people will always argue that somethings could have been done better. Fanfictions only exist because people weren't satisfied or they wanted to fantasize someone else or themselves in the picture. But, in the end, this whole series is their art and I think it is artful how Yang and Mercury seem to compliment each other and it doesn't have to be a ship even. I believe they were made that way to either be enemies or friends or, as I theorize, a ship. No matter who ends up together, I appreciate the series for what it is. But it's just like something has aligned in my head. I can ship them but, I respect it if nothing happens. It's just all in good fun for me. I can handle shipping a couple that may never sail.
