A/N: New story… I've had this idea for a while but I couldn't find the right characters for it. But luckily now I have them! Yeah. So. This is my first time writing an Adventure Time story, although I have RPed once or twice with it. So forgive me if it sucks.

Warning: Some parts of this story may be seriously depressing.

I have the main plot kinda planned out already, so I really don't have an excuse to get stuck on a chapter, and you can hold me to that.

The main pairing is Marshall Lee x Fionna, but there may be some side pairings. I don't know yet…

Also this is set in high school AU, so Marshall isn't a vampire; he just acts real stereotypically punk-like so he's considered part of the "emo crowd". And LSP isn't a floaty purple fluff ball. He (yes they are all gender-bent) just wears a lot of purple and has a lot of 'tude. LSP is his initials. I think that's all for the AU business… Any questions just PM me or just review and wait for me to respond in the next chapter.

Okay enough rambling here is the story.

I don't own anything!

*Prologue*

Fionna was happy. That's what mattered, right? If a friend was happy, you were too. Well, not this time around.

If being with Marshall made Fionna happy, friends shouldn't try to interfere.

But some friends weren't happy about Fionna and Marshall being together. Namely, her friends nicknamed LSP and Ice Queen.

LSP wasn't his real name of course, just his initials. He wore a lot of purple and had a major attitude. He does not approve of the two.

Ice Queen wasn't her real name either. However, she acted so highly and better than everybody else, Fionna started calling her Ice Queen, because she was so cold. Honestly, to Fionna she was more of an "on-and-off" friend. She does not approve of the two.

Gumball, however, was Fionna's best friend. He didn't particularly like Marshall, but for Fionna's sake, he accepted it. Fionna trusted him, but once he turned to LSP and Ice Queen, the trust began to fade slowly. Fionna could really only trust Marshall.

Gumball felt guilty over time. But, he knew Fionna was far beyond repair. He was afraid. He was afraid he had lost Fionna's trust forever.

LSP didn't was to lose a close friend, but he didn't know the things he said hurt Fionna. In a way, he didn't know how powerful his words were in a negative way. He didn't know he was losing her.

Ice Queen was an interesting character. She often did not hold back to voicing her opinions, and was mainly the reason Fionna gradually became depressed. She had a lot to say, but refrained from saying it face to face. That only made Fionna think she couldn't truthfully speak to her face.

Fionna and her friends were all senior students at Guardian High School. Out of all her friends, only Marshall and LSP could drive. The others still did not pass their driver's exams. Fionna used to walk to school, but now that they were a thing, Marshall drove her every day, to and from.

It was mostly people out of Fionna's friend circle who didn't mind, and in fact liked their relationship. But unfortunately for Fionna, it had to be her friends who absolutely hated it.

A/N: I know it's short but it's only a prologue. I just want to hear what your opinions are, so review and tell me!

If you guys really like it, I'll update it. But right now, with two other stories still in the process of being written, I don't know when I'll update this. I'm actually going to write the chapters in a notebook first, instead of just winging it at my computer like I do with my other stuff. So hopefully when you guys want another chapter it'll be completed for the most part.

So please please please please review and let me know what you think! Buh-bye!
