DISCLAIMER: I don't own Adventure Time.

Marshall's P.O.V

"Where are those two?" I said as I ruffled my raven black hair. "They should be here hours ago… Maybe I'll call them." I picked up my phone and dialled their number. It went straight to answering machine.

"Hey I'm Cake and I'm Fionna. We're not here right now because we are either fighting monsters or partying with cloud people. So leave a message." The answering machine clicked.

"Oh hey girls. Are you two coming today? It's jam time. So call me'kay?" I said as I put down my phone. " Might as well work on a song until they get here or call back.." I picked my guitar and started strumming. It sounded flat so I tuned it.

*SNAP*

Crap...just my luck...One of my guitar string broke...I set my guitar down. Can this day get any worse…

*RING*

My phone! Fionna! I immediately grabbed for the phone and picked it up. "Hello?"

"Marshall, I got your message. Sorry I didn't picked up. I called as soon as I heard your message." The young adventuress said.

"So are you and Cake coming today?" I asked.

"Umm… sorry to tell you this Marshall…but Cake and I won't be coming for jam time today…Sorry…" There was a hint of guilt in her voice. I tried my best to hide my disappointment. "It's cool Fi but may I know why are you cancelling on me?"

"Cake is going to stay at her bf's house for a week and she says I'm supposed to look after the house. Beemo can't stay at home all the time…So yeah I'm stuck at the treehouse..I am sorry again for not going for jam time…" The way she said this makes me wonder. For one reason my head says she is hiding something. "No worries, Fionna. It's okay. Bye Fi"

"Bye Marshall." She put down the phone. Maybe I'll go check on her. Just to be safe.It was the middle of the day and the sun is unforgiving today. I floated to my room and grabbed a black long sleeved hooded jacket with a pair of black gloves. I put them on and set off to Fi's treehouse. I can feel the sun's rays penetrating my jacket but a little pain doesn't hurt…much…

As I arrived at the treehouse, I heard voices. Must be Fionna and Cake. As I floated closer, I heard Fi's voice but no Cake's. Oh yeah, Cake, Bf's house.

"Are you sure no one's around?" someone spoke. Bubba…Figures…Fionna loves him because he is as sweet as candy…Yeah right more like downright sour… What's he doing here anyways? I edged closer to the nearby window.

"Unless you don't count Beemo and the occasional lava man that come to our house then we are alone. Cake is at LM's house for a week. So we have the entire place to ourselves." She replied with a flirtatious tone.

I peeped through the window and saw the blond haired adventuress and the pink flesh candy prince. My eyes widen and I went crashing to the ground. I quickly got up and ran. My hood of my jacket fell off, exposing my skin to the sun's rays. The pain was unbearable but not as painful as what I've just felt.

I ran as fast as I can. When I reached my home, I slumped down behind the door, feeling frustrated. I realized I could have flew home but something was weighing me down. The pain from the sun was starting to fade away but the pain in my chest was aching. Oh My Glob… I can't believe it… I just saw Fionna and Prince Bubba Gumball kissing… The first person ever who broke me from my depression of being alone for hundreds of years is kissing my most despised enemy… The world must hate me….

Tears flowed down my cheeks. I didn't bother to wipe them. I saw across the room,my base guitar. My guitar which string broke….My heart broke….
