This is something that popped into my head one day and I just went with it. I don't own Adventure Time or any of the characters. This is only the first chapter and I know it isn't very good or original but I'll take any reviews to make the rest of the story better. I hope you enjoy it.

As the door lord took my favorite night shirt, the one Marceline had given me so many years ago, I could feel my throat constrict. Of all my material possessions this held the most history. This was the only one I didn't want to lose, not when I had already lost her. I chased after him, and found myself in a familiar setting, her voice called out but I couldn't bring myself to turn around.

After he disappeared behind the door with many displeased faces I banged on it. I couldn't lose it. Not now. I have to admit I wasn't paying much attention to the people surrounding us, taking BMO apart to create music had me pretty distracted, until I heard that familiar voice singing again.

"La da da da da,"

I looked up surprised, she had a ridiculous outfit on, a yellow sunhat and matching cleaning gloves.

"I'm gonna bury you in the ground," she was staring right at me, I could feel a blush but I quickly tried to hide it with an expression of anger.

"La da da da da,

I'm gonna bury you with my sound,

I'm gonna drink the red from your pretty pink face,

I'm gonna..."

"Marceline, that's too distasteful!" I could tell I struck a nerve when she looked at me with a hurt expression, maybe I shouldn't have used those exact words but I really couldn't think when she was around.

"Oh, you don't like that? Or do you just not like me?!" Before I could even retort she rose higher and started playing.

"Sorry I don't treat you like a goddess,

Is that what you want me to do?

Sorry I don't treat you like you're perfect,

Like all your little loyal subjects do,

Sorry I'm not made of sugar,

Am I not sweet enough for you?

Is that why you always avoid me?

That must be such an inconvenience to you,

Well... I'm just your problem,

I'm just your problem,

It's like I'm not, even a person, am I?

I'm just your problem

Well, I-I-I-I-I-I-I shouldn't have to justify what I do

I-I-I-I-I-I-I shouldn't have to prove anything to you

I'm sorry that I exist, I forgot what landed me on your blacklist

But I-I-I-I-I-I-I shouldn't have to be the one that makes up with you

So... why do I want to?

Why do I want to...

To... bury you in the ground,

And drink the blood from your… Ugh!" The door must react to the truth because now the displeased faces were back. I stared at her, angry, confused, but most of all surprised. She hadn't sung with that way to me in a very long time. Granted I drove her to it, but still the emotion was there. Did she still love me after all this time? Glob knows how many nights I stood up thinking of her after I put her name on the blacklist, regretting it with every ounce of sugar in me. Could it be that after all this time all I ever had to do was apologize?

After I ran back into the door from which we came I stayed in Marceline's kitchen waiting for her to eventually appear. Finn and Jake ran by, quick enough not to see me, but Marceline noticed. She always did.

"What are you doing here princess," there was a lot of bitterness that had never been there before. She floated away without an answer.

"We need to talk Marceline," her bass hit a couple low notes.

"I remember the last time we did that princess, do you remember that day? The day you decided to ban me from your kingdom? To break my heart?" she was shouting now, her hair sticking up on all ends fueling, she started hissing and I really didn't know what to do.

"That hasn't stopped you from living out here." She hissed and her eyes became the dark spheres I flinched and looked away.

"Get Out, can't you tell I don't want you here?"

"That's not what you said in the song,"

"It was just a stupid song, a song I wrote years ago" she said through gritted teeth, "now if you will." She opened the door and pointed outside. I sighed and shook my head.

"I just wanted to apologize Marcy," the tears were threatening to fall now; "I miss you."

"Don't you get it princess? You were right that day, I don't belong with you, I'm too…" her eyes betrayed her and turned back to their original color, "distasteful." With that she slammed the door behind me and started played her bass very loudly.

"Marceline!" I banged on the door trying to get her attention back, she couldn't leave me again. I could tell she wasn't going to open the door so I started the trek back to the castle. My heart weighing down every step. I made the mistake of letting her go once before, and as a good scientist I learn from my mistakes, I'd make things right even if it meant one hundred failed experi-uh attempts.

Hopefully it wasn't too bad, reviews are welcome and the next chapter will be up soon.
