Finn is literally having the best years of his life. Adventures with his best friend Jake, saving the Land of Ooo from its brink destruction, hanging out with a vampire and even being a hero are his favourite past times.
However, there's still something missing. The Human Boy doesn't actually know what but it is pretty important, that he is sure. Something that would turn his life upside down either in a good or bad way.
He was waiting for the Spark to ablaze the fuse of the firework that'll finally catapult him into the venture of genuine happiness, exploding galaxies, burning hell fire, and most importantly, love. Still quite not sure if this explosion will affect his life in a tragic or dramatic, or, perhaps, both.
