Marshall Lee the Vampire King and Fionna the Human are like brother and sister. They adventure, fight evil, complete dungeons, and just plain hang out together. An invitation to a wild party with ghosts, vampires, and other various creatures is awkwardly accepted. But sternly accepting to play extreme truth or dare seems to change their relationship into what seems like love. Their relationship goes through guilt, addictions, love, kissing, the truth, and those who want them apart. Was that extreme truth or dare game for the best... Or for the worst?
(I DONT OWN ADVENTURE TIME... sadly)
