I really want to write a fanfic and I have an idea of what I want to write but never have written one before so idk what to do and If I should post it and actually write it or ask another acc to do it but here is the idea and let me know if I should actually attempt it and since I have no life I would prob be able to

Story plot***************************************************************************************************
So the story starts with a flashback of you and juggie in elementary school when you first met the another when you shared a moment then moments of you guys at the twilight drive in then goes to present time of you telling him you love him after school when your at pops in your favorite booth. He rejects you. And tells you that he has only ever thought of you as his best friend. You leave heartbroken and your mom (who is basically the serpent queen since she helps FP run the serpents) decides it's best to send you to an all girls school to help with your writing and photography ( because those are our interests) and she has been considering it for a while blinded by sadness and anger you agree and leave without saying goodbye to you best friend jughead. Then you come back around the time Jason gets murdered but totally different. As in your confident and bold and dress how you wished you could have before but never did because you were self conscious. You had a total glow up. You come back and are determined to stay away from the man who broke your heart but he slowly slithers his way into your life and then the romance starts
