(Note, something's have been changed to 'I'm Just Your Problem'. I did this on purpose to make it fit with the story line. I do NOT own the song or the lyrics.)
The two girls sat quietly in the captain's quarters, Bubblegum leafing through the many shelves of books that were in the cabin while Marceline was softly strumming her guitar... Which was proving to be a bit difficult since her hands were wrapped up snuggly. Even with the restriction she played flawlessly, causing a spark of admiration in Bubblegum's eyes. The combined pitch of the guitar and the low tone of the captain's voice blended perfectly into a beautiful meld of music. It was proving to be quite a distraction to Bubblegum's reading. Not that she really minded.
The pinkette took a seat on the vampire's bed, where said vampire was loftily floating as she played. She glanced over at the princess with a Cheshire smile before dropping down next to her, ending her note with a low hum. "Marceline, that was wonderful. You would be beyond famous if you ever went on tour." The captain chuckled, leaning against Bubblegum as she rolled her eyes. "Yeah, famous with every police officer, bounty hunter, and candy guard this side of Ooo." she replied, Bubblegum scoffing. "You know what I meant." "Hmm... Can you blame me? The opportunity was perfect."
The princess stuck out her tongue in a rather immature manner, Marceline returning it with a laugh. "Lighten up, Gumdrop. I'm just messing with you." the vampire muttered, snuggling up to a now marooned faced Bubblegum. She nuzzled against the other's neck with a sigh, letting her breath hit the princess' pink skin. The royal shuddered, quickly pulling away from the vampire with a nearly orchid colored blush.
"So, you're a princess and a raingecko? Who knew royalty could change colors?" Marceline teased, laughing at the rather cross look Bubblegum gave her. "I fail to see the hilarity in this-" "And I fail to see how you're still so proper after being with a band of pirates. Seriously, no need to be so elegant, your Majesty." The pinkette smirked, clutching the cover of the book she was still holding.
"I'm not a queen yet, mind you." the princess stubbornly huffed, earning an irritated growl from the captain. The black-haired girl scowled before returning her attention back to her guitar, strumming the strings furiously. The strums quickly turned into a line of chords, the low hum of the bass gently vibrating inside Bubblegum's chest. "... Dada da da da..."
Bubblegum watched as the vampirate started to vocalize the soft humming like she had before, the words slowly forming as the chords continued. "La dada da da, I'm gonna bury you in the ground... Dada da da, I'm gonna bury you in my sound... I'm gonna drain the red out of your pretty pink face, and..." The sudden flinch next to her caused Marceline to stop, her eyes igniting crimson as she was interrupted. "What?" she questioned, glaring at the princess who was watching her with cautious eyes. "Ugh... It's just a song, I'm not going to do anything." she grumbled, Bubblegum partially frowning. "I'm sorry. I didn't mean... It was just a little...distasteful for my liking."
The vampire's red glare intensified as she once again began to strum the axe, a few blotches of red staining the bandages on her hands and arms. "You don't like it? Or maybe you just don't like me?" The princess blinked in confusion. "What-" "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."
"Marceline, you're bleeding-"
"Sorry I'm not made of sugar; am I not sweet enough for you? Is that why you always confront me; that's such a low blow, even for you." The words were sung out sternly as if they were rehearsed, the vampire slowly closing her eyes. "I guess I'm just your problem, I'm just your problem... I shouldn't have to be the one who has to protect you, so why do I want to...? Why do I want to..."
The captain stopped her singing, opening her eyes to see Bubblegum staring at her. Her expression was unreadable, and even her eyes gave nothing away. "... Stop staring at me! You threw me off!" The princess squeaked as Marceline suddenly swung her axe upwards, the weapon smashing into the roof of the cabin in a shower of splinters. And there it stayed as the vampire vanished in a swirl of shadows, leaving a stunned pinkette alone in the dim room.
