1 Work in Finn the Human/Flame Princess/Marceline
A couple of years go by before Finn finally decides to ask one of his lady friends out on a date by the end of a week on the celebration of "Heart Day". If he works hard enough and overcomes all his self doubt when it comes to him and the girls he might end up having a pretty good time.
