So, this is my first Fanfic . . . that I've done alone! :D So anyway; don't hate, just read and relate!
Finn was sitting on a large tree stump, thinking about why he felt so empty. "Why?" Finn asked no one in particular. He looked up at a tree to see a small caterpillar munching on one of its leaves. "Hey there little guy," Finn said as he crept closer to the oblivious creature. "It must be easy to live the way you do, not having to think about who's where or what's when, only having to eat. And then you get to turn into something beautiful like a butterfly or moth," Finn looked at the slowly setting sun, "I wish I was a caterpillar." "Finn?! Finn! Come on man, where are you?" Finn looked up, his train of thought broken by the sound of Jake's voice. "There you are! Dang bro, I couldn't find you anywhere. What uh, what are ya' doing out here?" Finn sighed and turned around, saying nothing, only staring at Jake with a look on his face that said 'help me.' "Um, are you okay dude, you look kind of . . . not so good," Jake asked now becoming increasingly worried. And Jake was right, he didn't look good, in fact Finn looked terrible; his skin was of a sickly pallor, the hair underneath his hat was completely disheveled, and his eyes looked as if he hadn't slept in days. "Oh yeah, I'm fine," Finn wasn't even looking at Jake, more like at the air around him. "Okay . . . well din-din's ready, are you hungry?" Jake hoped that the thought of food might get Finn out of his funk. "It's a new recipe, how does Lasagna sound?" Jake asked with a big smile on his face. "Huh? Oh yeah, whatevs," Finn had taken to looking at the ground under his feet. "Is there something you need to tell me about? 'Cuz you know I'm always here for you, right?" "Yeah sure, look I don't want to talk about anything right now okay?," Finn began to walk away, not hearing his brother's shouting for him to come back behind him and slowly disappeared into the forest surrounding the glade they were in. 'Man, I've never seen Finn act so mopey before,' Jake thought as he started walking back towards the house. 'I'm sure he'll be all right, he knows how to handle himself. Maybe he'll be better if he has some time to himself.'
Finn, walking to nowhere in particular, was staring at a small, tear soaked piece of paper: a drawing of Flame Princess. 'Oh glob, why did it have to be her?' thought Finn. He remembered how happy he had been when they first started going out: life had been good for Finn during that time; they would walk together and Finn would show her all of the things that he thought were cool. But there had been one thing that Finn had buried in the back of his mind: she was a fire elemental. The day that he doubted it would work between them was the same day that he crammed the thought deep into the confines of his mind, into the same place that nightmares and other terrible memories could be found. He had done so unconsciously, wanting so much to be happy for once. It was on the day that Flame princess almost destroyed all of Ooo, after he had saved her, that he had thought that it was over, that his hopes of being happy would be destroyed forever. But then he found out that they could kiss through things, and all was well again. They had continued doing this for some time, all the while Finn secretly thinking that it was ridiculous. He would have told her that, but two things had stopped him from doing so; the fact that he didn't want to hurt her feelings, and his incessant longing for happiness. 'Maybe it will get better someday' he had told himself. Much to his dismay, however, it never got better; in fact it had only gotten worse. Thanks to Jake's lack of communication on the subject of growing up, Finn never learned about the many changes that he would be going through at his age. This began to tear Finn apart on the inside, his newly developed wants subconsciously making him stress out, even at times of happiness, such as his birthday that had passed only a few days ago. It was this unknown force that had made him finally decide that kissing through rocks was stupid, when he told her this, she had gone into a rage, barely allowing Finn to escape with his life. He hadn't told anyone what had happened, not even Jake; he thought that if he kept it all a secret, the pain would go away. But it never did, it grew with every passing day, until Finn ended up sitting in a glade, talking to a caterpillar and asking himself 'why?' Why was there no one that he could be with normally? Yes, he understood that Princess Bubblegum was a candy person, but the worst thing that might happen if they were to interact would be that he might get a little sticky. But she had turned him down countless times, even on the day before his birthday. Jake had even gone to great lengths to help him out, not knowing that his choice would later make Finn more depressed than ever before.
Finn stopped to see where he had ended up. He looked around, noticing that he was familiar with his surroundings. "Oh yeah, this is where I helped those two spiders out with their relationship" Finn said aloud as a smile found its way to his face. He was glad he was able to help people like that; he couldn't stand seeing people in distress. But then he glanced down at the picture of Flame Princess, and the small amount of happiness vanished, replaced by anger "How can I help other people with relationships, but then completely mess up with my own?!"
With that, he crumpled up the sketch of Flame Princess and threw it as far as he could into the forest surrounding the path he was walking on. "Ha! Take that Flame Princes!" Finn was smiling at the thought of being over her, but it didn't last long. "Wait," Finn fell into a cold sweat, "that was the only picture I had of her!" Finn ran into the bushes to see if he could find it. He was crawling on his hands and knees, searching frantically for the small piece of paper that was his only tie to the days in which he had been happy. He was just about to give up and had tears in his eyes when he heard a rustle to the left. He heard a growl and reached for his sword, as he realized it wasn't there, he stopped and tried to think of a plan. When he couldn't come up with one, he just tensed up and waited for whatever was to come.
I know it's a little short, but I promise they'll get longer and better!
