The demons inside

Ok so let me make this absolutely clear. I do not own anything from the show adventure time. Or own the cover photo, all I own is the made up story. Alright, there's my disclaimer. Please enjoy my first ever Fionna and Cake Adventure Time fanfiction! Go ahead, hate if you want. If I get enough reads maybe I will make this like, super long! And if you do hate on this, just know that I know, your hate only means that it's good enough for you to care, just not like. I try to stay on the same line in Finn and Jake. Sorry if I don't. You may begin now!
