A/N: I recently got into Adventure Time again because of Bubbline and Simon. And Gunter. There's not much substance to go at in these chapters, but enjoy.
Chapter One
Finn sat in a stool in Princess Bubblegum's lab, gabbing on about a recent adventure he had. Bonnibel was only half listening, focusing more of her attention on the experiment at hand. As she carefully poured the right amount of ammonium hydroxide into the beaker, Finn mentioned his recent encounter with the vampire queen, Marceline.
Taken aback, Bonnibel accidentally spilled all the ammonium hydroxide onto the floor.
Finn stood up, worried that the princess might have hurt herself. "Woah, you okay, Peebs?" Finn asked, crouching down to pick up the larger fragments of glass on the floor.
"Uh, yeah," Bonnibel managed to get out coherently, "My fingers slipped." She figured that would be enough to satisfy Finn, and it was. She began helping him clean up her mess.
"Oh, alright. If you say so," he replied.
After everything was cleaned up, he began to continue his story about Marceline and his tree house.
This time, Bonnibel was fully listening, ignoring all the tangents and digressions Finn went into sometimes. She hadn't seen or heard of Marceline since the fight.
"I wonder if she's doing well," Bonnibel thought to herself, her mind drifting. "When did she even come back?"
She regained focus on Finn's story as he began blushing and stuttering. "She gave me a kiss on the cheek too," he said quietly, embarrassed.
"She what?!" Bonnibel practically yelled, but quickly tried covering up her uproar, "Oh, I see."
Finn took no note of the little uproar, lost in his thoughts.
