This is my first fanfic. Go ahead and give me some constructive criticism please!

In the land of Ooo, sat Finn, the hero. It had been a few years since he last defeated the Lich, but in the process, paid a terrible price. The Lich called his army of evil and it took all of Ooo to stop him. Around the same time, Finn had just turned seventeen, and he had proposed to his fiancée, Flame Princess, in the midst of battle. She accepted proudly and made Finn the happiest man alive. This love drove Finn to defeat the Lich in battle, but even though the Lich had fallen over, he was not dead. When Finn least expected it, the Lich uses his mind control as a dying command. He took control of Flame Princess and used her fire ability to manifest and self destruct. Though no one died during the battle itself, the blast was big enough to kill many others. Those among the dead were Prince Gumball, Marshall Lee, and Simon Petrikov, who shielded Marceline from the blast. Even though Finn was the one closest to the blast, Flame Princess's love protected Finn with a blue flame. Before Flame Princess passed away, she left Finn with a few words. "Finn, you have to keep living. Always remember that no matter what happens, I will always love …." It took Finn a long time to truly understand the meaning of these words.

He had mourned her for years. Every night, his brother, Jake, the dog, would wake up and find that Finn was gone. He searched frantically throughout the tree house, even though he knew where Finn would be; where he always was. Jake went to the outskirts of the Candy Kingdom, where all of the heroes from the war were buried. He saw Finn asleep by Flame Princess's head stone. He would pick him up and take him home to his bed. He did this for 5 years.

The truth was that Jake was afraid that Finn would take his own life. So he started to call up a few friends; a set of friends who went through the same thing: of losing someone that fateful night. First on the list was Fionna. On that night, Fionna had also lost her husband, Marshall Lee Abadeer. As soon as she got the call from Jake, she hurried over to the Tree House. Finn had locked himself in the bath room, along with the demon sword. Fionna and Jake busted down the door and knocked Finn unconscious. What they had found in that bathroom made them shiver down to their very bones. Finn had mutilated himself and wrote down a suicide note on the wall in blood. This is what it read.

Jake,

I cannot stand living anymore. I see Flame Princess everywhere. She is in my dreams and in my reality. I see here in the candy kingdom, at the graves, and I even see her in the bathroom mirror. I should be frightened, but I am not. I realized that I longed to be with her. I hope you and Lady Rainicorn have a long and happy life together.

With love,

Finn

Finn awoke in the hospital surrounded by Jake, Lady Rainicorn, Fionna, Bubblegum, and Marceline. They all stood by his side with tears in their eyes. When it was dark, everyone had left except for one person. That person was Marceline. Marceline had stayed by Finn's side throughout his stay at the hospital. Even Jake had to leave to tend to his children.

"Why are you still here, Marceline?" grumbled Finn.

"Because I am your friend, Finn. Friends go out of their way for other friends. That is something I learned from you." What Marceline had said had slightly lifted Finn's hopes, something Finn hadn't felt in 5 years. But Finn was still depressed. "Finn, you need to get out more man. Jake tells me that you don't do anything besides stay at home and play BMO all day. When was the last time you went on an adventure?"

"It was over 7 years ago. I think it was with Flame Princess. She nearly torched the entire cave…" Finn started to sob again.

"Oh Finn…"

"I was just… like… ready to settle down, ya know? I just… I knew that she was the one. I was fucking ready. And then that fucking asshole took everything away from me!" Finn was sobbing as if the world was going to end the next day.

Marceline was quiet with tears in her eyes. She couldn't say anything else to Finn that would cheer him up. The only thing she could do was let him yell, while she held his hand to comfort him. Finn screamed his heart out and Marceline just sat there – sat there, not floating like what she usually does. Marceline wouldn't budge, even when Finn had screamed himself to sleep, and when he would wake up, Marceline was still there, in the exact same spot where she had always been. As Finn stared at the upright sleeping Marceline, it dawned on him that perhaps he was beginning to understand the meaning of Flame Princess's last words. He stared into the mirror located on the vanity next to the hospital bed, for the mirror was one of the many places where he could see Flame Princess. "Is this what you meant?" She nodded her head and although she was inaudible, Finn could understand what she said.

Goodbye Finn. I love you.

Of course, it still took a while for Finn to truly get over Flame Princess, but eventually it did happen. Ever since that day in the hospital, Finn and Marceline saw each other every day, even only if it was for a moment. They would have jam sessions and picnics at night, and if the night was really busy, Marceline would just drop by the tree house to say hi to Finn.

One day at Marceline's place, Finn decided to cook her dinner. Although a terrible cook, he decided that he would make a grand gesture and prepare Marceline a feast. He headed towards Marceline's place. When he reached Marceline's place, knocked on the door. Marceline opened.

"Hey hero. What are you doing here?"

"I thought I would come over and cook you some dinner. Seeing as you don't eat anything that isn't red, and that I don't have anything to do with my night. I thought that I should hang out with you."

Marceline complied and allowed Finn inside the house. The inside of her house wasn't that different in characteristics in comparison to Finn's tree house but the visual was astonishing. It was a little messy inside with a devil may care attitude. Marceline's instruments were littered all over the floor. The walls have been painted over with a mural, maybe because Marceline had to take her mind off of losing Simon. The place looked different, but it didn't bother Finn. To him, the place was the same old place where they would have jam sessions. "Make yourself at home hero. Just don't walk into the bathroom while I shower."

"Hehehe…. Okay…" Finn blushed, thinking of the time he saw Marceline nude in the bathroom when him and Jake were hiding in Marceline's closet. Finn began to cook, or act like he was cooking. Really, he was just admiring Marceline's amazing mural paintings. The paintings were representations of all of her favorite places in Ooo. There was the red eternal abyss of the Nightosphere, the pink lusciousness of the Candy Kingdom, and the dull, yet homely tree house that Finn lived in. Moments later, Marceline stepped out of the shower.

"Are you sure you don't want me to help?" asked Marceline. Finn turned his head and couldn't help but be entranced by her outfit. She was wearing a low cut dress top along with a short skirt. She had striped black and white stockings. Coupled with that amazing body of hers, Finn could not stop staring.

After a few seconds, he broke out of his trance, shaking his head. "Nah, I got this."

"Okay then. I am going to go get a strawberry jelly doughnut, you want one?"

"Sure," Finn looked away in an attempt to hide his red face.

When Marceline arrived back home, Finn had an entire feast prepared.. Everything was red, from strawberries, cherry pies all the way to ice cream. It was evident that Finn didn't make this, but Marceline appreciated the gesture anyway. They both had a great time that night. At the end of it all, they walked in the moonlight, talking about the things they have done together up to that point, especially beginning with the first time they met, when Marceline kicked Finn and Jake out of the tree house. They laughed, and they cried, but they had fun.

"Hey Finn?" asked Marceline.

"Yeah?"

"Can I tell you something?"

"Anything, Marceline." Marceline stopped walking. As Finn turned around, she walked straight up to him, nearly touching his nose with hers. At this point, Finn had outgrown Marceline, and Marceline was finally beginning to see that.

"I am starting to like you, Finn." Finn's face turned red. "I mean, when I'm with you, I feel alive. I haven't felt alive for a long time. I spent the last couple of years mourning over Simon but all he wants is for me to be happy…." Marceline began blushing, "And I know I am happy when I'm around you. What I am saying is… I want to go out with you. What do you say?"

Finn was speechless. Marceline thought she scared him off, but just as she was about to apologize, Finn hugged her for a long moment. "C'mon Marceline. Lets grab a movie." Marceline smiled and nodded.
