This is always a hard thing to answer because I like so much xD I usually like slice-of-life, romance, supernatural, horror/thriller. I'm open to pretty much anything but I'd say those I listed are probably the ones I enjoy the very most. As for tragic or light hearted I kind of like a balance. I like relative realism in that I want there to be a mix of good and bad, lightness and dark if that makes sense. I don't want something that's too obnoxiously lighthearted but nothing that's gonna make me want to hurl myself off of a bridge either.
