Each fanfic authors have their own style. Me, I prefer writing without worrying the reactions of the readers. Not that I don't care, I mean, of course I get happy whenever I receive good feedbacks, but, I just write what I want. And sometimes, when I write stories that doesn't have a happy ending, readers complain or sometimes get 'hate' from them. But I don't really get affected, though. Not all stories are fitting for a happy ending. Or rather, it'd be much better off without an unrealistic happy ending. You know what I'm saying? Like for example; an obsessed man who's gonna do anything just to get his love interest. And even going as far as kidnapping him and abusing him. Now, you can't really expect a happy ending with that one, right? You can't force yourself into someone and hope for the best outcome. It's ridiculous. Well, at least in my opinion.
