The important reason to have an introduction is that when you are going to write a story then the Introduction is the one that is going to start and begin the story. I think is really important to make it a very good introduction is because sometimes when you take time on it then that will make the reader get more into the story and read it more and more times. Sometimes you also have to write it because how are the people going to know what the story is going to be about maybe they might not like it , they might say this story Isn't good I'm not going to read it maybe it ugly.
