it is a yes (if you're willing that is). My guess on why you dropped the fanfic is you don't know where the story will go. If so then I suggest trying to make a timeline or a mind map. If you don't know what a mind map is, a mind map is a way of linking key concepts using images, lines and links (or you can just google it). Use the mind map or timeline to put your ideas and scenarios in the fanfic so you can have a script or notes to continue your story without doing it on scratch. Example #1 MC goes to USJ, villains comes out what should MC do? A. Use his shadow army to kill all the villains. B. Let the plot continue without interfering.And after choosing which scenario you like build your story around it and add dialogues and details.TLDR uses mind maps or timelines on your stories to make life easier. (This strat helped me in making original DND compaigns like demon slayer, etc)
