What is the opening doing? The opening of this story is giving you details about William's life then it starts to talk about the girl he met  and her shoe. In addition to this, it went into the sensual part ,and I think this is like hook to keep the audience reading the story to see what else will happen next or if the author can keep their flow to have your attention to make you continue to read after the sensual part she as mention. Moreover, it talks about William liking to watch pornography and what type of video he likes now that part was a little too much information. Apart from this, for someone who wouldn't like these language the starting or the opening will give you a heads to not continue to read if you find these sensuality disturbing. As well as that, the opening kinda tells you what the flow of the story will be like or the things it will mention.
