Or then there's something seriously missing in their own lives, or they're bored, so they write down their own daydreams. Lol. And of course, that type of thing seem to be rather popular too, so money can also be a huge reason. I'd imagine those people would probably laugh all the way writing their books...
....My daydreams have always been way different and more along the lines of creating worlds to escape to and have my own epic adventures. If there was ever some romance, it was more of a side story type of thing. I actually still remember pretty well my first "real" world where I used to go to. Kind of miss that place, because it was really fairytaleish.
