I read a lot of manga, and sometimes in the margin (usually in shoujo, or girl's) the author takes a panel away from the story to write whatever comes to mind. It can get annoying, but I've come to enjoy reading the trivia about the manga-ka (the author). Since most novels don't break the story like that (not that I'm a published author or anything, that's just what I want to be), I'll put my Free Talk in this blog.
