"Are you...blushing?" Bonnibel asked, snickering.
"What, no." Marceline denied. Her cheeks tinted pink, contradicting what she said. She tried to hide it by pulling her scarf up but, it was too late.
"Did I just get the ever-stoic, hardcore, total badass Marceline Abadeer to blush?" Bonnie grinned and poked Marcy's side.
"No... It's... It's the cold." Marceline mumbled into her scarf. Her face was barely visible but, the tips of her ears were bright red.
"Huh. It's the cold. And not that I told you, 'your face is freaking adorable and, I bet the rest of you is too?'" Bonnibel teased Marceline, grabbing her arm and hugging it.
Marceline blushed more and said, "N-no," her voice cracking. She turned her face away and used her other hand to cover her face.
"Alright then, if you say so," Bonnie smiled softly and swung their hands between them.
"Y-yeah." Marceline stuttered, still blushing furiously. They continued walking, Bonnibel humming something and Marceline fiddling with something in her pocket.
