So book concepts will be divided in different categories such as Parody, FanFic, Fiction, and so on.
Any idea that is R-18 then it will be marked in the title.
The ideas will have a mock title or a description on the chapter title with (1), (2), ... meaning examples of chapters for the idea.
The first chapter is just an outline of the concept.
I'll make edits to this as I go along.
