Hey, I'm an AruRan fan too. You speak for the whole community when you say that. Me, I like characters separately, then couples. Even though it's AruSherri, I still support AruRan because I still think they are perfect together. (And it has nothing to do with me hating Sheryl, I actually like her voice and dress style, plus her character makes me smile sometimes.) Bashing on a whole community is kinda low...
As for bittersweet endings:
But on a soft note: at least we can look forward to the amazing battle scenes, right? XD
