its where someone writes a story about characters of a tv show, a book 或者 a movie and writes about something that they think should happen in the future, 或者 something like that. 或者 a different storyline including characters from a book, movie 或者 TV show. Like me, I'm working on a Percy Jackson fanfic, Harry Potter, Lord of the Rings, and 海军罪案调查处 fanfics
