It was the TV show that wrote it. The creaters/writers of 성 and Nathan Fillon wrote it, to give the show a new curve. A real writer, off of a TV show..... with a book in that TV show.... and that book is in stores. Think about it. Would 당신 get hooked on a TV show if your favourite author is on it? I certainly would. I hope I answered your answer, good enough! :)
I think it's fantastic how they make the 책 look like 성 really wrote them when 당신 know he didn't. Even the Bio on the back cover. Very ingenius. rockynj
