Chapter 1- Emotions

This is a different book entirely from my other fanfic I hope you enjoy it. And also make sure to look at my other books.
Fionna has been 17 for a couple of months now and Cake has been back and forth between Lord Monochromocorn's house and their tree house, and Fionna is fed up. Is a little surprise from Marshall all it takes to get her mind off of cake?
Warning! This will be very fluffy!
