As I've seen some others do, this story uses a very different kind of CHYOA as a spring-board for the writing: various protagonists, male and female, will match with one or more of the deities in the following CHYOA, the first chapter will describe who matches with whom and why, but, after that, things can go quite a bit off the rails, as slowly various other parts of the initial CHYOA and its results are revealed. Whatever else you need to know, it is either covered in the "Writers Guidelines" for the story, or soon will be if you send me a message with a question that isn't covered yet in there.
