A/N: My apologies ahead of time if there are some mistakes! I wanted to get this up quickly!
Flame Prince felt his face warm as a red blush crept onto his face. He felt Fionna's hot breath on his cold face. He glanced at her pink, smooth lips which were only centimeters from his. Fionna felt her own face warm up as she stared into Flame Prince's intense eyes. His cold breath hit her warm cheek and she gingerly lifted her arm placing her palm on his icy cheek.
"Wow you are cold." Fionna gasped felling the Prince's chilly cheek. Flame Prince's blush deepened as he searched for something clever to say. Luckily, Fionna spoke before he could. "Maybe I should get some blankets." she asked sitting up.
"Y-yeah. Maybe you should!" Flame Prince snapped. Fionna jumped at the sudden exclamation and tripped on her feet letting out a surprised yelp. "Look out!" Flame Prince grabbed Fionna's arm, but instead of keeping her from falling back, he pulled her light body down and she fell on top of the prince. They didn't even have time to react when their faces crashed into each other and lips touched.
Their eyes widened and hearts beat quickly against their chests. They were frozen in the moment unable to even flinch. Thoughts ran through the two minds.
"Her lips are so soft."
"His lips taste like coal."
Fionna pulled away first and stood up with her face tomato red from embarrassment.
"Oh Glob I'm so sorry!" Fionna stammered with her hand slightly above her mouth. Flame Prince remained sitting up on the floor, his eyes wide with shock and face red as he stared at Fionna. She bit her lip. "I-I'm going to go get those blankets." She dashed up the stairs avoiding eye contact with the prince.
Flame Prince sat still with his eyes wide. He felt his lips tingle and his heart beat loudly against his ribs. His fingers hovered above his lips. He couldn't believe he had just kissed a water elemental!
"Maybe this can work after all." Flame Prince thought.
He felt a light cloth fall on his shoulders and turned looking up seeing Fionna there. Her beautiful golden locks were covering her expression, but her face was still red. Stiffly, she returned to her seat by the fire a few feet from Flame Prince. She held her knees up to her chest and attempted to hide the embarrassment from her face. FP couldn't help but grin at Fionna's childish behavior, but he didn't like the uncomfortable silence settling between them.
"Thanks for the blanket." Flame Prince said politely.
"No problem." Fionna mumbled.
"Aren't you worried about your ca-sister?" he asked trying to stir up a conversation.
"Nah. Cake got what she deserved. She'll probably just stay at Monocromicorn's till the rain lets up." Fionna said casually.
"Mono-who?" Flame Prince asked with curiosity.
"Monocromicorn. He's Cake's boyfriend. They-" Fionna sneezed and sniffed. FP looked over in concern.
"Are you ok?" He asked.
"I'm fine. Don't worry about me." Fionna said with a hesitant laugh. Flame Prince wasn't convinced. "L-look, the rain stopped. You should probably get home before your mom kills you." FP looked out the window in surprise. The sun was out and it was as if it wasn't storming just hours prior.
"Well, I guess." Flame Prince hesitated with his words. He and Fionna walked over to her front door. The light blue blanket was still draped around his shoulders. Fionna opened the door.
"Um, I guess this is goodbye?" Fionna said sadly.
"Yeah, I guess." Flame Prince took a step outside. For once, his boots didn't burn the grass right when he touched it. Fionna was about to close her door but a boot prevented the door from shutting.
"Wait." Fionna looked up at Flame Prince who stood facing her. "Back there, when you saved me. Did you mean what you said? Do you really like me?" he asked. Fionna felt her blush return. There was a pause as FP waited for his answer.
"No." Fionna responded. Flame Prince looked surprised. "I don't like you." Fionna opened her mouth to continue, but when she looked up, the prince was already gone. Tears flooded her eyes and she sank to her knees.
"I don't like you." Fionna repeated, her voice trembling. "I love you." She buried her face in her hands letting out a pitiful sob. She couldn't hide it anymore. She loved the prince of the fire kingdom.
A light cloth draped around her shoulders and she gasped as she felt an arm wrap around her shoulders.
"I love you too."
Fionna didn't even need to ask. She knew who it was. She leaned into his chest and felt her body relax at the sound of the prince's quick heartbeat. She enjoyed his warmth. It wasn't too hot as to burn her, but it wasn't too cold to cause her to shiver. He was just right. Fionna snuggled closer to the fiery warm prince. Her prince. Her personal fireplace.
Fionna blinked her eyes open trying to adjust to the dark, and looked around in confusion.
"Where am I?" she whispered. She felt soft animal pelts under her fingers and her orange sleeping bag nearby. "I'm…in bed?" There was a soft purr and Fionna looked over to see her sister sleeping soundly in her wooden drawer. Was all that a dream? The adventuress let out a disappointed sigh and tried to sit up only to feel pain all over her body. She flinched, her hand reaching to her side feeling a bandage around it. She brought her hand up to see a thick bandage wrapped around her palm. She threw off her sheets.
Bandages and pain covered her body. Just by the feel of it, she could tell they were burns, and deep ones. She winced at every movement and her mind flooded with questions. What happened to her? Looking over, Fionna found her answer. A burnt piece of paper rested on her bed stand. Gently, she reached over and unfolded the paper. It was yellowed and the corners were charred. There was rough handwriting with blotches of burn marks scattered on it.
Fionna,
I'm sorry to leave you behind so quickly, but we can't be together. It looks like I got better because I burned you again. No matter how hard we try, it's just not going to work. I still love you, Fionna, but it's best we stay away from each other, that way, you'll be safe, and I can't hurt you like I have.
Love you always,
Flame Prince
Fionna felt her heart sink.
"That explains the bandages." She whispered sadly. She felt her tears threaten to fall once more and crumpled the paper in her fist. "Why can't I just like a boy?" Fionna looked out the window. A faint path of burnt grass could still be seen. Before she knew it, she was in her signature blue skirt and her mom's blood sword strapped to her green backpack. Fionna headed out the door, making sure to leave a fake note for Cake, ready to confront the prince once more. She may have let Prince Gumball slip away from her, but she wasn't going to let this romance burn to ash.
