Marceline was getting prepared for a Candy Kingdom concert. It was a place, she was fond of, especially given her rather complicated bond with Bonnibel Bubblegum, or some as some prefer to call her Princess Bubblegum. She's mostly checking her amps for now, to make sure she has the right tone that she wants. She's going to perform covers and songs of her own.
She appeared satisfied with the tone her guitar was giving off, it didn't sound too loud or lifeless. So, it was good enough to work in her eyes. The thing about Marceline is that she mostly has a nonchalant way of living life she doesn't fret things too much, but she does have her exceptions and can get emotional at times. The setup for her gig was in pristine condition which made her feel elated.
Her gig starts in about two more hours, giving her plenty of prep time to look at the setlist and tweak things at her disposal. She's developed a loyal audience over the years who are enchanted by her voice and playing. As she's getting ready to strum a riff, she feels a tap on her shoulder. She turns around and sees you. "Oh, hey there what's up? Are you a fan or a jerk?" She asked you with a puzzled look on her face.
