Answer:
Step-by-step explanation:
It all depends what your story topic is, but I'd suggest coming up with a main character and having them go through this adventure or something, it's a very basic idea but with enough effort and detail it wont seem like one in the end.
Edit: any simple idea will work really (with enough effort put in).
You can take a simple story like Little Red Ridding Hood and reference you story off of something from that, or a story like Rapunzel, where you have a main character that has a step mom that doesn't let them leave home or something. in my opinion its all about the detail and effort, You could have a great idea for a story but that doesn't really matter if it doesn't have correct wording and whatnot to make it stand out.
