~Burning Low~

The Land of Aaa at night was as peaceful as it was in the morning. The stars twinkled in the night sky, but they were no match to the luminous full moon that glowed almost as bright as the sun. But something else glowed brighter that night. In the outskirts of the grasslands, near the edge of a cliff, stood a burning wooden house that didn't crumble away from the flames. Fionna the Human and her best friend/sister, Cake the cat, were putting the finishing touches to the house for its new resident, the Flame Prince. Fionna's boyfriend.

Fionna's stomach did flips and tricks every time she called him her boyfriend. She couldn't be any happier than she was with the Flame Prince. At first their relationship started off rocky one month after the Goblin Kingdom incident; The Flame Prince found Fionna's house and asked her to accompany her for an afternoon stroll. He had apologized for his actions before and told her about his feelings he had for her. Fionna nearly cried as she told him how she felt too. The two were relieved and overjoyed. Flame Prince took Fionna on a date to the Cavern of Shiny Objects and asked her to be his girlfriend; of course, Fionna said yes.

Eventually, the couple hung out more often. Their dates usually consist of eating, having fun doing random stuff, and adventuring somewhere; the day would usually end by saying goodbye or, if the mood asked for it, hugging. The couple got to know each other even more. Flame Prince, stubbornly, still said that Fionna was a Water Elemental since she can produce water from her body, but Fionna would argue back saying that she wasn't a crybaby. He came to learn that Fionna was fighter; an experience one at that. She loved collecting swords and weapons and she enjoyed roughhousing every now and then. As a fighter, the Flame Prince was itching for a duel with his girlfriend, but that itch was quickly dismissed, for he promised himself he would never lay a hand on his princess ever again.

Fionna learned that the Flame Prince had a real name. Aidan. Prince Aidan Flame of the Fire Kingdom. Flame Prince hated his name and he didn't allow anyone to speak of it, not even his mother. But when she asked of his real name, she said it. The Flame Prince wasn't mad or angry; he just told her not to say it in public. Fionna giggled as he witnessed his face intensified in heat. Apparently, he loved Flambits and Fire Lions. He had a Fire Lion at home named Flambo that he played with every day. He told Fionna that when he was younger, he would purposely destroyed citizens of the Fire Kingdom just so he could play with little Flambits. Fionna had to remind herself that Flame Prince was, supposedly, evil.

Fionna and Flame Prince were a match made in heaven. When Fionna found out that Flame Prince was homeless, she knew she had to do something about it. Fionna understood why he didn't want to go back home to his evil mother and decided to build him a small house a couple of miles away from her tree house. Cake and Fionna gathered as much magical non-flammable wood as possible in order for the house to not burn down to the ground. After four hours of working, playing, and romantically gazing into each other's eyes, Fionna and the Flame Prince have managed to finish the house. Fionna did one final inspection just to be sure.

"There! You're new house is finished!" Fionna cheered excitedly. She turned to her feline companion, who was resting on top of a rock. "Cake! C'mon, you gotta see this!"

The cat stretched and watched the scene before her. "Nah, it's okay girl. I'm fine over here!" Cake the cat was happy to see her sister happy with another prince, but Cake's suspicion about the Flame Prince being evil never left. There were times where Flame Prince's rage would slip and would cause havoc again, but he quickly recovered and fixed his mistakes. Cake knew that he was trying his best to be good, but there was something about the Flame Prince that Cake couldn't shake off, making Cake feeling uneasy around him. She just hoped that Fionna know what she was getting into.

Flame Prince stared at his new house excitedly. "I'm gonna go check out the interior." He dashed into his house and assimilated with the fire. His flames engulfed with the fire and his fiery head burst itself on top of the house. He smiled and laughed happily. "This house is so bombastic! I love it!" Fionna cheered happily along with him. Flame Prince reverted back into his original state and stood next to his girlfriend. He smiled. "Fionna. This is the greatest gift you have given to me. I'm so happy."

Fionna's smile was so big that she could have sworn her cheeks were about to explode. She was willing to do anything that would make the Flame Prince happy. She blushed and suddenly found the ground more interesting. "Well…gosh…it was…nothing special."

"It's getting late." Flame Prince said as he noticed the moon for the first time. "You should head home. I'll walk you." He offered gentlemanly. Fionna thought it was sweet when he acted like a gentleman, even though he was stubborn and arrogant most of the time. Before Fionna could reply, Cake stepped in between the two and hissed at the Flame Prince.

"That's okay fire boy! We'll be fine just on our own." Cake pushed Fionna to head back to the tree house, but the Flame Prince could let her go just yet.

"Wait! Fionna!" The girls halted in their tracks and watched as the Flame Prince ran into his house. Fionna heard items being knocked down and crashing sounds and the Flame Prince swearing every now and then. He emerged in a suit of armor that covered his entire body. He extended his arms out to his princess.

"Hurry up and hug me before this suit melts." He demanded. Fionna blushed and giggled as she ran up to him and wrapped her arms around his neck, while the Flame Prince wrapped his armored arms around her slender waist. He savored every embrace he could get from her. He took the scent of her body and committed it into memory. She smelled like nature and vanilla. Odd combination, but it suited her greatly. Fionna felt safe in his arms, even if they were covered in a sheet of metal. She felt like she belonged in his arms, like he was the missing puzzle piece. Fionna felt the suit of armor heat up and she knew it was time to let go. The two ended their hug and stared into each other's eyes. Fionna blushed.

"Bye."

"Bye." Fionna and Cake walked back home. Fionna took on last look from her prince and waved him goodbye and he returned the gesture. Cake turned to her sister.

"So, I guess you're date went pretty well, huh?" Fionna looked down and blushed harder.

"I don't know…he hugged me. Does that mean anything? Are hugs like a special guy code for something?!" Fionna panicked.

"Whoa, whoa girl, calm down. Let me explain something to you." Cake morphed her arm into a series of a long staircase. She point at the first step. "Right now, you're at tier 1, which is hugging. But soon, you'll make it to tier 2, which is kissing. Then he'll take you to tier 6, where he'll show you all fifteen feet of his beautiful dark body! And then you'll get to tier 8, where he'll let your wildest desire to touch his horn become a magical experience." Cake sighed romantically as she fanned herself from all the heat her body was having.

Fionna pondered and pointed to the final step. "What's tier 15?"

"YOU STAY AWAY FROM TIER 15! IF HE MAKES YOU GO TO THERE, I'LL CLAW HIS EYES OUT!"

"Cake, I have no idea what you're talking about…"

"Just let everything go naturally. I'll work itself out." Cake covered her nose. "Girl, you need a shower."

"What?!" Fionna examined herself for the first time today. Her clothes were covered in dirt and leaves and her shoes were muddy. Overall, she smelled like mud and dirt. "Oh my Glob! I was around the Flame Prince looking like this?! Ugh! This is so embarrassing!"

The girls arrived at their tree house. Fionna was determined to head straight to the shower before she did anything else. Once Cake opened the door, they saw Prince Gumball of the Candy Kingdom stuffing large amounts of gold in his sack. He saw them opened the door and greeted them.

"Good evening ladies."

"Prince Gumball?!" They exclaimed together.

"What are you doing here?" Cake asked.

"Collecting taxes. You two weren't home, so I let myself in." He explained.

"Oh." Cake said. Ever since Fionna hooked up with the Flame Prince, Fionna and Cake would only be around Prince Gumball if he really requested for their assistance. Fionna was officially over her silly crush she had for the candy prince and she thought it was best to move on.

"I'm gonna go take a shower." She raced past the prince and climbed up the ladder into their house. Prince Gumball stared at her. She didn't greet him like she always did. He turned to Cake.

"What's the matter with Fionna?"

"She's just tired from running around with her new 'gentleman friend'." Cake giggled. Gumball was intrigued with this gossip.

"A 'gentlemen friend' you say? Tell me more." Prince Gumball smiled.

"It's Flame Prince! She's going out with Flame Prince." Gumball's pink, bubblegum skin turned pale as he gasped.

"Oh no…This can't be possible…" He back up against the wall and his breath staggered.

"Oh its possible." Cake said, not noticing Gumball's change of character. "I can't believe it myself."

"I just never thought…and with…Flame Prince…" He sneered. "I have to go." He quickly ran out of the tree house and toward his kingdom. Cake raised her eyebrow.

"I wonder what's wrong with him."

Prince Gumball ran up the castle to his chambers, not even saying his greeting to his loyal subjects. He slammed the door opened and buried his head in his pillows. He clutched his pillow in his hands. "No…I thought I would be ready for this…"

The next morning at Fionna and Cake's lovely tree house, Cake was busy moving a glass mirror to the other side of the room. She heard her sister slid down the ladder and quickly examined herself in the mirror Cake was holding. Fionna's attire was different today. She wore a white tank top with a light blue hoodie and blue shorts with black boots. Cake smiled. "Lookin' cute Fionna!"

"Thanks! I'm off to see Flame Prince. I'll be back later." As soon as Fionna opened the door, Gumball stood there dressed in a lavender suit and a pink tie.

"Fionna!" He greeted. Cake hand slipped and the glass mirror fell. All Fionna heard was the sound of shattering glass. The candy prince let himself in. "I need to talk to you about relationships."

"T-that's okay, Gumball…" But the Prince ignored her and pull out mini projection screen from his pocket.

"I just want you to understand something…" Prince Gumball began his long lecture about relationships, the earth and something about explosions. Fionna and Cake were nowhere near paying attention.

"Cake, I gotta go." Cake nodded as Fionna ran out the door. Cake tried to pay attention to Gumball's lecture until she saw a piece of string. The feline loved string! Cake pounced on the string and played with it to her heart's content. There was nothing better in this world for Cake right know than that string.

"Cake! Cake!" Prince Gumball shook Cake to get her attention away from the string. "Where's Fionna?!"

"She went out."

"Well, please tell her why she can't see Flame Prince anymore." Cake pondered at Prince Gumball for a second before realizing what was going on.

"Okay…" She folded her arms. "I'll tell her."

"Perfect. I cannot stress how important it is that they not see each other." And with that, Gumball made his leave. Cake shook her head.

Later that night, Cake was busy playing a video game on BMO, when she head Fionna enter in the house.

"Hey Fi."

"Cupcake! What did Prince Gumball want?" Cake put the controller down and stared at Fionna.

"He doesn't want you to see Flame Prince anymore because he's insanely jealous, girl!" Fionna frowned. Now after almost two years of falling in love with Prince Gumball, he breaks her heart. And now that she had found someone else to love, he asked that she not see him anymore. What was his deal? Fionna ignored Gumball's request. "So how was your date with Flame Prince? Did he kiss you yet?"

Fionna shook her head. "He gave about five hugs." She giggled. "Does that count?"

"Nope!" The girls giggled. Cake jumped off the couch and led her sister to their room. "C'mon, I know exactly how to get that boy to kiss you!" The girls spent all night trying to find a perfect outfit for Fionna. Obliviously, dresses were out. Then Cake convinced her to wear lip gloss tomorrow, saying that Flame Prince would go crazy if he saw her wearing it. Eventually, the girls climbed into bed, but Fionna couldn't sleep. All she could think about was the Flame Prince and she knew that she had to convey her feeling out. She pulled out her notebook and pencil and started thinking.

She thought about the Flame Prince. He was so bright, brighter than the shining sun. He was handsome. Prettier than all of princes Fionna's ever seen. She felt confused when she was around him, like something warm and comfortable was filling up her chest to the point where she can't breathe. He was dangerous and deadly, but she wanted to be around him more. These feelings she felt for him were contradicting each other left and right and Fionna wanted it all. She couldn't stand this! She was so in love but she couldn't explain why.

Dawn arrived as the sun's rays peeked through the window. Fionna needed to go on a walk to clear her mind. She silently slipped on her outfit; a dark blue shirt with a blue sweater, black skirt, white knee-high socks and boots. She grabbed her green backpack and silently walked out of the house without waking up anybody. She walked to hill that over looked the grasslands. It had the perfect view of the sunrise.

"Perfect inspiration." She sat down and began writing her poem. She ripped away sheets of paper that she thought weren't good enough. However, she wasn't aware that Prince Gumball was walking up the hill behind her.

"Fionna." He said. Somewhere in the background, Fionna heard the sound of shattering glass. "What are you up to?" Gumball asked innocently.

Fionna turned to greet him. "Um…Good morning Prince Gumball. I was just writing something…for Cake." There was no way Fionna was going to mention her boyfriend to Gumball. Gumball took a seat next to Fionna.

"Speaking of Cake, did she explain everything to you?" He asked softly.

"Yes…?"

"And did you understand?"

Fionna turned away from him angrily. "Yeah. I understand."

Gumball sighed. "Fionna. Sometimes, you want someone and you want to kiss them and be with them." He grabbed her hand with both of his hands and caressed it gently. Fionna was startled by this action and wanted him to stop. "But you can't, because responsibility demands sacrifice." Fionna released her hand from his hold.

"What are you trying to say?!" She yelled.

"I'm saying you're a hero Fionna. You're my hero." He smiled. "So I'm glad you understand why you can't see the Flame Prince." He sighed in relief. However, Fionna stood up and her face turned red in fury.

"Gumball! I can't take this anymore!" She yelled startling the prince.

"…what…?"

"Now you like me?!"

"Fionna…what are you talking about?"

"What am I talking about?!" Fionna shook her head to prevent tears from falling. "I WAS IN LOVE WITH YOU GUMBALL!" She shouted. "But you didn't love me back. And now when I've found someone else to love, you start building me up again! Well I'm done with you! Okay?!" She looked down. "I'm done…" She said softly as she ran down the hill away from him.

Prince Gumball sat on the hill amazed and flabbergasted. He never knew that Fionna had felt that way for him and to think he hadn't notice until she told him. He felt horrible about it. "Oh Fionna…How could I have been so blind." He stared down at the ground until he saw a crumbled piece of paper. Probably Fionna's. He picked it up and read it. "…..oh no."

Without a moment to lose, Gumball took off running towards the girls' tree house and barged in without knocking. He climbed the ladder and saw Cake next to the stove cooking breakfast. "Cake!" He startled the cat so much that she jumped up and stuck her claws to the ceiling.

"Prince Gumball?! You can't just—!"

"I know, Cake and I apologize, but where is Fionna? Is she with Flame Prince?" The magical feline released herself from the ceiling and landed on her feet. She glared at the candy prince.

"Why should it matter to you?" She sneered.

Gumball clutched the note in his hand as he tried to control his anger. "Is she with him? Or not?!"

Cake hissed. "You heartless jerk! Do you know how much she's cried over you?! She deserves to be happy with someone she loves! Even if he's evil and she'll melt her face off! You should be ashamed!"

Gumball stared at her in disbelief. Didn't he already explained this?! "This is not about some stupid love triangle! Flame Prince is physically unstable! The elemental structure in his body cannot handle extreme romantic pressure! If those two so much as kiss, he's body will break down into cataclysmic explosion and he will melt down to through the planet's crust and straight to the core! Then the Earth will burn from the inside out until all life has turned into ash! WHY DO YOU THINK I HAD HIS MOTHER LOCK HIM UP?!" He yelled.

Cake gasped. No words could describe how horrible this is.

"WILL YOU TAKE ME TO THEM NOW?!" Cake calm turned off the stove, grabbed the price, grew in size, crashed a hole in their house and ran like there was no tomorrow. Prince Gumball jumped on Cake's back as she started to run on all fours to increase her speed. "Faster!" He commanded. He just prayed that they weren't too late.

The Flame Prince's burning house was in view and Gumball saw Fionna reading a poem to the Flame Prince. Gumball's heart stopped in fear of what would happen next. Fionna's note was burned into flames and the couple laughed. Flame Prince stared into Fionna's eyes and before he knew it, he grabbed her shouldered and quickly pulled her into a kiss.

"NO!" The flash of light touched the sky the temperature around them increased into an unimaginable heat. Fionna, Cake and Prince Gumball were flung back a few feet from the blast. Fionna groaned from the pain and opened her eyes.

"Flame Prince?" He was gone. All was left was hole where he stood. She crawled towards the hole and looked down and saw him helplessly sinking down the to the Earth's core. "AIDAN!" Before Cake and Gumball could reach her, Fionna took off her sweater and jumped in the hole after the Flame Prince.

"FIONNA!" Cake tried to reach down to grab her but Prince Gumball stopped her.

"Wait!" He jumped off and pushed a large bolder over the hole.

"WHAT ARE YOU DOING?!" Cake yelled.

"Listen! If we deprive the reaction of oxygen for about 24.8 seconds, we can stop the Earth from burning into a crisp!" As he predicted, the flames around them grew weaker. "...He'll go out."

Meanwhile, Fionna continued to free-fall until she crash landed to the ground. It was dark with little to no source of light and the air supply was extremely thin. Her lungs were screaming for some air and quick and she felt her body around melt from heat. But Fionna didn't care. Her eyes caught sight to still body in front of her. "Aidan!" She ran to him and wrapped her arms around him as she shook to wake up. He felt cold in her arms. His body was grey and lifeless. This didn't suite him at all. Fionna's eyes started to water as she held him close.

"Aidan…Please…wake up. I need you…" She huffed. "I can't stand…to lose you…" She was blacking out. "I need you…to be…okay…" With one last deep breath, Fionna locked her lips within his and exhaled.

Instantly, the Flame Prince's flame was reignited. The jewel on his forehead grew brighter than ever and his Mohawk stood ablaze.

"Huh?" He checked his surroundings and saw Fionna lifeless on his lap. "FIONNA!" He took her in his arms and flew up the hole. He broke through the bolder that blocked his way until he was greeted by the outside. Gumball and Cake were astonished that the Flame Prince made it out stable and alive.

Flame Prince laid Fionna on the ground and stood back to give her some air. "Fionna…" He cried as his knees gave way. Prince Aidan, for the first time in his life, was scared. He was scared that he would lose the very thing he cared most in the world. He loved Fionna, this he knew without a doubt. He wouldn't be feeling these…confusing feeling for her if he didn't. He couldn't afford to lose her. He couldn't imagine a life without her. "Please…wake up…"

Gumball and Cake ran toward them, but Flame Prince wouldn't allow it. In anger, he turned towards them and yelled, "GET BACK!" He threw a wave of flames at them, but he purposely missed. He heard a cough. He turned around and found his girlfriend coughing. She opened her eyes and stared at him as she adjusted breathing.

"Are you…" She coughed. "…okay?" Flame Prince had never felt so relieved in his entire life. He was so happy to know that his love was safe. He nodded softly.

"Yes…I'm okay." He smiled and collapsed next to her on the ground. The two laughed. Flame Prince examined her body. Her face was completely red and her lips were black from kissing him. He felt so stupid for putting her into harm's way. AGAIN! His thoughts were dismissed when he met with Fionna's eyes once again. At least she was okay.

Prince Gumball witnessed the scene before him. He saw Fionna, burned and scarred, picking up a rock and kissing it, and then she passed the rock to Flame Prince, who gave a face that said "You're out of your mind". Then Flame Prince reluctantly took the rock and kissed it as well, but he threw it away muttering how stupid that was. Fionna giggled. Gumball sighed.

"Good. He's stable….at least for now…."

As Gumball saw the couple, he felt something sting at his heart. He didn't like the way Flame Prince smiled at Fionna. He didn't like the way those two laughed when they were together. He didn't like Flame Prince together with Fionna. It felt so wrong. He didn't like it.

He hated it.

Cake gave a small smile. "At least they're okay, and everything is back to normal."

"They shouldn't be together…" Prince Gumball whispered darkly. Cake stared at him.

"What did you say?" The prince coughed at shook his head.

"I was saying that they look perfect together. I am happy that Fionna has found someone to be happy with." Gumball lied.

"You jealous?" Cake smiled mischievously.

"Shut up…"

I'M ALIVE! YES! I promised you more Fionna and Flame Prince and I shall keep my promise! I'm happy to be making a couple of one-shots about one of my favorite Adventure Time couple. I hope you all will enjoy it. Especially since my other Adventure Time story got over 2000 views. ...I mean...damn people...that may not be a lot, but that's a lot to me.

I know you have a lot of comments about this so let me blow most of those out of the way before you nag me about it:

1) Flame Prince's name. Aidan. Means "little fire". I like it. If you don't, hey, whatever.

2)Fionna's outfits. It was harder than I expect it would be. I'm sorry, but I just felt like she didn't need to wear the same thing everyday. That's just me.

3) Yes. Flame Prince has a giant Fire Lion named Flambo. Not to be confused with the regular Flambo. I didn't make it up. I check with my sources just to be on the safe side.

Well I hoped you enjoyed it!
