Marceline's POV
"I love you too."
I couldn't speak. I just stared at Finn in shock. Finn pulled me onto his lap and cried into my shoulder. We stayed like that for almost an hour and neither one of us spoke a word. Once Finn had calmed down, he stood up.
"Marcy, do you know why you're not floating?"
"No."
"Why don't we take you to PB? She might know what's wrong."
"Okay."
After a running a few tests, Princess Bubblegum came back into the room.
"You're a human."
"What?"
"Marcy, you're a human."
"How is this possible?"
"When a vampire falls in love with a mortal they become human. So who is it?"
"Oh um..."
"Come on Marcy tell me!"
"Finn..."
"Aw! You guys are so cute."
"Uh.. Thanks."
I walked into the garden where Finn was waiting.
"Finn..."
"Yeah."
"I'm human now."
"How?"
"Well um... You see... I fell in love with you and you're a mortal and that kinda makes vampires not vampires anymore."
"Oh. I'm so sorry Marcy."
"Why? I can finally go out in the sun and eat normal food again. I'll also age the same as everyone else now."
After the trip to the candy kingdom, I had dinner at the tree house. Jake was at Lady's house so it was only Finn and I. When the meal was over, we sat out on the roof.
"It was cool to be able to eat food again. Thanks for making dinner Finn."
"No problem. Anything for my favorite human."
