This is really interesting, I wonder where the writer will take it.

I wouldn't recommend this if you are looking for an actual romance. The novelist is a manipulative bastard and the editor lets him get away with far too much. It's very interesting from a psychological standpoint though. (and, you know, sexy times) edit: WOW AND I THOUGHT THE FIRST STORY WAS WIERD. all of these are very... dysfunctional relationships. They all have happy endings (as far as that goes) but uh... just make sure to read the tags first, okay?

I'll admit, I usually don't go for the whole "fujoshi & fundanshi" thing but this situation is really interesting! not sure if I'm going to stick with this one, but it's first chapter has certainly drawn me in. (I really want to know what the MC looks like, though)
