This isn't an original idea but I can't get monster falls out of my head so I'm writing a fanfic.
Though now that I think about it, I have tried to make my Monster Fall's fic as unique as possible... Let's see how that goes.
This will be my first billdip fanfiction and I'm not that good so please I would like it you guys reading this book could give me advice on how I'm going.
