These are small sections I believe are part of an overall story and some pieces may be edited to fit the plotline so not everything will add up or make sense. Also some parts of different stories may sound like other written stories take, The Beast Within: A Tale of Beauty's Prince by Serena Valentino for example. Full credit to people like this.
