·Marinette's Birthday·

She had noticed changes in Chat Noir's suit a month or two before her birthday, she had to admit, he looked pretty- well, what was the word to describe it? Did she find Chat... Hot?

His bell was pulled down more, revealing the start of his chest. His add on claws were sharper, and his hair was messier than she expected.

Despite his new look, he still had that sly, playfully grin on his face. She was curious to why she hadn't experienced this change yet. -but now, her kwami was sitting in front of her- ready to tell her.

"Happy birthday Marinette! While you were asleep, I modified your costume for you, I hope you like it!" The kwami smiled warmly, eyes gleaming her usual happiness.

"Thank you, Tikki. What would I do without you?" Marinette questioned, pulling the kwami to her cheek. The small kwami giggled softly.

"For one, you wouldn't be Ladybug." Tikki stated. Marinette happily winked at her, before standing back up.

She ruffled her hair, playing with the blue highlighted locks. Her mind immediately pulled to Chat Noir's constant teasing- she giggled softly at the memory.

"M'lady! Guess what!" Ladybug turned towards her partner, her eyes immediately trailed down to his slightly exposed chest- before she caught herself, pulling her gaze to make eye contact with him.

Obviously, he caught her gaze. A smirk appearing on his face as he leaned forward- towering over her. "Like what you see?" He flirted, gaze warm with amusement.

She rolled her eyes, suppressing her embarrassed blush. "What is it? And why did your suit change?" She questioned- pushing him back with her finger.

"I'm an adult now, I can finally move out and live my life!" He mewled happily.

A smile graced her face. She was happy for him. "Happy birthday cat." She scratched his chin, making him purr slightly, rubbing against her gloved hand.

"I think I deserve a birthday kiss." He declared, green eyes flashing with mischief. She sighed, before pulling his head down to her lips. Pecking his forehead.

Immediately, his arms wrapped around her waist. Greeting her warm lips with a gentle purr that continued until she pulled away.

"Only one." She scolded, pushing his face away from her and struggling out of his grasp, he huffed in defeat.

"I can't believe you're an adult before me." She groaned in annoyance. She had always thought that Chat Noir was younger than her- because of the way he acted. Childish and reckless.

"Sucks to be you." He smiled, pulling of a ridiculous pose, showing off his biceps. She couldn't help but stare, but he didn't notice- since he was to busy rambling about how he was better than her.

She sighed, snapping out of her daydream when she heard her mother call her.

"Marinette! Come down here!" Sabine called- Tikki gave Marinette an encouraging smile, the girl made her way downstairs, greeted by her parents.

"Happy birthday! You finally have the ability to move out! I expect you to move out in a month by the way." Her mother challenged, Marinette was about to protest- but a high-pitched scream interrupted her.

"I have to go!" Marinette mumbled, racing upstairs. She locked her hatch, before calling her transformation. She immediately felt different, her gaze trailed to her mirror.

"Woah." She mumbled softly, her suit still had black spots, sure, but now- a black splotch covered her chest, along with her arms and hands.

She noticed that the ribbons in her hair had not only grown longer, but curled lightly. She had to admit, she looked- well, grown.

Her gaze lifted to skylight- she immediately climbed onto her bed and pushed it up. Enjoying the sharp breeze. She already noticed that Chat Noir was fighting, his baton swinging at the akumatized victim.

"My name is Sleep Raider! Someone has disobeyed my need of sleep, so I shall make Paris feel my pain!" The akuma roared.

"Pound it!" She called, fist bumping with Chat Noir. His eyes glazed over her, his breath hitched.

She cleared her throat, making him turn his attention towards her. "What's wrong? Lady got your tongue?" Suddenly, she was pulled into a hug.

Hesitantly, she wrapped her arms around him, his arms were wrapped around her waist, batting at her yoyo slightly.

"Happy birthday m'lady, I have a present for you." He chuckled in her ear.

"Oh really?" She coughed, smiling lightly. But her expression went neutral when he pulled away. Suddenly feeling colder.

He kneeled down, grabbing her hand and kissing it. "I want you to move in with me for now, you don't know how lonely it is." He whimpered softly, ears drooping.

She opened her mouth to protest, but she immediately closed her mouth when a gave her a sly, baby doll look.

Great.
He knows her weakness.

She bit her lip, before groaning. "Okay." She mumbled, immediately, he pulled her down and into his harms.

"Chat Noir!" She scolded as he stood up, holding her to his chest as her legs wrapped carefully around his waist.

"Hold on, let me show you!" He chuckled, flinging off.

She looked around the small apartment, Chat had just finished his tour.

"It's too big for me anyway." He mumbled- scratching the back of his neck nervously.

She sighed, pointing an accusing finger at him. "No identity reveal?"

He immediately pulled his hands up in surrender. "No identity reveal." He reassured.

"Good." She declared, before flopping onto his couch.

"I'll start moving in tomorrow, but I can't get my mattress in straight away- I would have to drag it downstairs- around four floors."

He chuckled at her. "Are you rich or something?" She shook her head, glancing at him with a smirk on her face.

"Im comfortable. To be honest, its a spiral staircase that leads to the actual house. The bottom is more or less a business." She yawned.

"Alright then." He mumbled, sitting down next to her. His arm draped over her shoulders. Pulling him closer. Just when she was about to protest- Chat silenced her with a finger to her lips.

"My apartment. My rules. No protesting." He scolded, innocently poking her nose. She huffed.

They stayed like that for awhile until her miraculous beeped. She struggled out of his grip. "Bye kitty." She waved thoughtfully before making her way out the door.

"Bye m'lady." He answered, but she was to busy flying through Paris to notice.
