A/N: Sorry if this is quite crappy, this is actually my first fan-fiction and it won't be about a theory, as my username implies. Criticism is okay, it'll probably make me better. To get started, I have no idea where this story will go, nor do I know how it will end, I'll just write it as I go and hope someone out there likes it. So, uh, here goes.
Disclaimer: I do not own Adventure Time or any of the characters mentioned in this fan-fiction and I never will, this is purely for entertainment
Why can't I stop thinking about her? I know that she most likely likes that pretty boy, Gumball, but my mind won't get off of her. Gumball, his voice repeated in my head as I sighed and stood up from the bed to pick up my bass, its sharp, red axe body shined in the dim light of the house. My fingers plucked the strings with power, making each note sound better than the last as they echoed in my ears.
I started to sing, an angry tone escaped my lips, and all I could think about was my utter hate for Gumball that I can never show to anyone. Just as soon as the song seemed to be getting more and more aggressive my mind just got back to thinking about her, her beautiful face just was all I could envision, and the notes started getting lighter. My fingers slowed down and plucked the strings lightly rather than hit them. All that was coming out now were soft lyrics about love.
"Stop thinking about her," I growled to myself. I grabbed the bass and almost slammed it to the ground as it made a loud thud noise. I floated around the house and went into my room, muttering to myself that it won't work out. "We're ages apart, she's really young and I'm over a thousand years old! It'll never work out. Gumball will always be better than I am!"
I looked around the room and saw that the bass had a small dent on one of the strings. I grew worried for half a second and thought about getting new strings but my mind, once again, started thinking about her. I threw myself onto the bed in frustration and stared at the ceiling, all I could see in the bumps in the ceiling was her. Fionna.
That's it. I must see her.
