AN: Because I had to
It's the simple things in life you enjoy, Ladybug decided, as she looked out at the nighttime cityscape of Paris. All was quiet, thanks to Hawk Moth's recent defeat, and that left open the opportunity for her and Chat Noir to catch up on some much needed R & R. They were still superheros, and probably always would be, but for now...
Well, for now she had a rather cuddly Chat in her lap demanding attention. She didn't mind though. He gentle scratches around his ears and along his jaw left him a happy, relaxed puddle of purrs that was quite therapeutic to have. She quickly found herself mischievously singing.
"Warm kitty, soft kitty, little ball of fur...
"Happy kitty, sleepy kitty, purr! purr..."
"PURRRRR!"
Only the weight of her partner's head on her lap kept her from jumping up in surprise at the sudden vibration she swore she'd feel all the way into next week. She stared down at Chat Noir as he looked up with a sheepish, uncomfortable grin.
"Sorry, My Lady. That song kind of holds... significance for me," he explained.
"Oh?" she prompted.
Chat was silent for a moment, before finally responding, "My mother would sing it to me whenever I was anxious, upset, or whenever she needed me to relax."
"Hmmmm..." Ladybug could feel her mischievous streak come back. "Fond memories of 'Warm Kitty', apparently really good at physics..."
"Don't compare me to Sheldon Cooper," he pouted at her. "I hate that joke." He'd already had it sent his way more than once as Adrien Agreste, by Nino, Chloe, Sabrina, Alya, and even Kim!
"Well if the collar fits," she quipped, flicking the bell on his suit. "But you're right. Sheldon Cooper would make a horrible Chat Noir."
Satisfied, he went back to purring, but she could resist adding the rest in her head.
But Chat Noir would make an amusing Sheldon Cooper!
