Welcome to the club Mattie!
I won't repeat what graeme and beastkid said, but they, of course got it right. Even at 117 pages it can still be called a story, I'm sure that we can find stories that, counting all the chapter, amounts to more than that. As for the characters running away on their own, well, try taking some time off, then return to the story you'll see it from another point of view, and that can be helpful. If not, well try to get yourself a betareader (or whatever) to read it and give you pointers.
don't worry about people wanting to read it!! I'm sure it's good.
again, welcome
