It has been one month since Flame princess broke up with Finn and he did not take it so well. After they found a way to enter the world of Aaa, flame princess met up with flame prince and they instantly connected. Finn was devastated and does not even leave the house, only to exercise because Pb makes him. Everyone is worried about him, but most of all Marceline, who knew this devastated him more than when Pb always rejected him. In hopes that he could cheer his brother up, Jake called Marceline to see if they could hang out while he went to Lady Rainicorn and their pups.
"Hay Marceline, do you think I could send Finn over to you so you guys can hang, while I take care of business. Like maybe have a jam session or something?"
"Sure why not, is he still moping around?" asked Marceline with a hint of concern.
"Ya hasn't been out in a few days, maybe to run or something, but he hasn't done anything." Jake sad turning to see Finn wrapped up in a blanket on the sofa in the fetal position.
"Okay send him over, it'll be fun to have a jam session." Marceline said and then hung up.
"Yo finn since I have to head to Lady why don't you go see Marceline, wadya say?"
"I mean I guess" Finn said with a blank face.
"Awesome, well then lets go".
Jake led Finn outside and grew so they can get to Marceline's faster with Finn who lazily climbed up jake and said nothing this whole trip. As they entered the cave and knocked on Marceline's door Jake left saying he didn't want to make Lady wait too long.
"Hay Finn how's it been, lookin good for a guy who never leave his house" Marceline said with a smirk.
"Thanks for letting me come over, I need something to get lost in that isn't Heat Signature"
"No problem well anyway, lets jam!"
After Marceline brought Finn inside they spent the whole day just playing their bass and guitar to some songs from before the Mushroom war, to making new songs, to just going crazy and playing random chords. For the first time since the break up Finn actually smiled and had a good time.
"That was totally ALGEBRAIC!" huffed Finn who was actually lying on Marceline's rock hard couch trying to catch his breath.
"Well weenie, no day with me is boring, but didn't know you can jam that hard, you even gave me a sweat"
Finn stares at Marceline just noticing how her hair is so black but its so beautiful on her. Finn never really liked talking about the break up, he never even told Jake, but now he feels that he can tell Marceline, what hurt him so much.
"What is it weenie, do I have something on my face eheh" Marceline says while blushing after Finn stared at her.
"Marceline, can I tell you what happened, I don't know, just to get it off my chest?"
"Finn, you came here to relax and hang not worry about drama."
"Ya I know but, I never told anyone and I just want to get it off my chest"
"Okay sure, I'm all ears Finn."
"Remember when we found that portal thing, in that underground cave with Peebles?"
"Ya that was a crazy adventure, never knew you could fight like that."
"Well I took FP there, I wanted to meet Fionna, that world's human, see what it's like to not be the only one."
"Okay then what"
Finn stops to think of what to say next, not wanting to have to remember the scene. "Well when we went through we got transported to their treehouse, and well Fionna was on a date, with I guess their Flame Prince. When we went up to them, they just stared at each other and went off somewhere to talk. When me and Fionna were done talking, we went out to look for them and found them making out. They said since they are of the same element, they don't hurt each other, and they connected so well, and they thought we should all just break up, then Flame prince took FP home I guess. Fionna started to cry and went inside, I just went through the portal again, and well then you guys saw me." Marceline looked at him now knowing what happened, and guessed more had happened but he doesn't feel ready to say it. Marceline never like FP, she always burned Finn, who already has so many scars and wounds from his numerous years of adventuring.
"Finn I'm sorry. That couldn't had been easy." Marceline hugged Finn, who seem to be holding back tears.
"Thanks Marceline for listening, you're such as good friend. But I think I should go its late, and Jake might be home, I don't want to have him worried."
"You sure?"
"Ya, well see ya." As Finn went to the door Marceline got up.
"Finn wait."
"Ya marc…" Finn was cut off by Marceline as she slammed her lip into his. All he could think about was how they tasted like strawberries. Finn didn't pull back, it felt too good, so they just stood at the doorway making out.
