Adrien didn't exactly know when his friendship with Marinette began. Maybe it was the first time they met with him in his superhero persona and she had actually ended up saving the day. Or maybe it was when he fell off of a roof and onto her balcony, smushing her favorite tulips, resulting in a pitcher of water being dumped on his head. Or, maybe it was the time where he photobombed her selfie and gave her bunny ears.

Okay, so maybe it wasn't just one thing that led to the two teenagers becoming very closer. Maybe it was a lot of things.

And so, here he was, sitting on her balcony railing and watching as she danced to the music coming from her computer. He couldn't exactly hear it and he didn't really care what it was, as long as it kept her happy and dancing like a child. Sometimes she would trip and fall, and he would chuckle with her as she got back up.

Finally, after being entranced by her childlike game, he made the move to make himself known. After all, if he stayed here he would definitely be called a stalker.

By her.

Adrien chuckled as he tapped on the window. Marinette turned around, her expression not at all surprised at his face peering in from outside. On the contrary, she let out a full blown laugh, her head tilting backwards. Skipping over to where he was perched, she unlocked the window and opened it.

The first thing that hit him was the volume of the music. It swung out and killed the beautiful silence that he had been inhabiting. Caught of guard, Adrien blinked several times and his face morphed into one of slight disgust and pain.

Marinette let out another laugh, and suddenly all those nasty feelings were gone.

Her bright blue eyes met his, the edges crinkled up in a smile. "Hello, Chat Noir."

The way his name tumbled off her tongue made his mouth twitch. "Hello, Princess. May I enter your castle?"

She grinned. "But of course, my black knight."

"Was that supposed to be a Monty Python reference?"

Marinette chuckled. "Man, this is exactly why we're friends."

Adrien smirked, tapping his chin. "And the fact that you give me free chocolate."

"Well, yes, that too."

The pair fell into a laughing fit. It was just so natural, their friendship. It had kind of started off slow with nothing more than awkward comforting and uncomfortable hellos and goodbyes; but then it had skyrocketed and suddenly they were watching Netflix into the wee hours of the night and playing pranks on each other. He didn't fully know how it had happened, but he didn't really care. Because she was the one true person that he could confide in. Nino didn't come close. She didn't take none of his crap and put him in his place. But she was also kind and was always there.

"Oh, speaking of which!" Marinette managed through her giggles. "I have something for you!"

She walked over to her desk and grabbed a plate filled with some kind of sweet, it didn't really matter to Adrien. Everything from her parent's bakery was delicious. He sat down on the floor and she joined him, handing him the plate. "Here. I was just about to watch some Attack on Titan. Wanna join in?"

Adrien rolled his eyes. "And here I was thinking you knew me."

Marinette replied with a stuck out tongue and an eyeroll of her own before she switched on her computer. She returned and settled into his side, like she always did when they watched movies together and began to eat the wonderful treats in front of them.

The blonde haired boy smiled softly at the girl nestled next to him. Normally, between other people, this probably would have been either considered a very awkward situation or something couples would be doing. But for the two of them, it was neither of those options. They were best friends, that was it, and right now that's all he wanted. Marinette was amazing, and he couldn't have asked for anyone better to take up part of his heart.

Things like hugs, playful shoving, laughing at three in the morning, they were just normal things for them. Sometimes, Adrien would fall asleep at her house and he would awake hours later with a blanket wrapped around his shoulders and a not saying that Marinette had left because his transformation had worn off and that there was food on her desk if he was hungry.

She took care of him. She was his shoulder to cry on. She was his partner to laugh with. She was his friend to confide it. She was amazing, in and of herself, and he wouldn't have her any other way.

Adrien didn't even know that his eyelids were fluttering to a close until he heard Marinette whisper, "Goodnight, Alley Cat."

Marinette adjusted the blanket once more before standing up and picking up the plate on the floor. She moved the pillow under Chat's head and pushed some of his hair out of his face. Walking over to her desk, she took a deep breath and glanced at the clock. The red numbers read 5:49 am. She sighed, shaking her head as she grabbed her change of clothes and headed to the bathroom. After she had gotten into her outfit of the day, she sneaked downstairs and "stole" what was leftover from her parents's breakfast. Giving in to her perfectionism, she arranged it all nice-like on a silver plate and set it on the edge of her desk so that he would see it when he woke up.

She sat down in her desk chair, smiling gently at the adorable kitty before her as she pulled out her sketchbook. She couldn't give up a chance like this, she thought, and proceeded to draw a quick doodle of his curled up body, covered in her fluffy red blanket, crumbs still dusting his mouth.

A beep sounded in the silent room, signaling his transformation. Marinette glanced at the clock once more and her shoulders slumped. She had better start to leave. Alya would kill her if she was late again.

Throwing her bag over her shoulder and stuffing the sketchbook inside the front pocket, she scribbled out a quick not and placed it on her desk. Glancing over her shoulder at the kitty nestled against her bed, she grinned.

She ascended the stairs as quietly as possible. She wished her parents a good day and walked out the door, inhaling the crisp morning air with delight. As she crossed the street, she smiled, casting one last look at her window.

He had always been there when she needed him, that cat. Whether it be for a laugh or a hug, he was always ready to supply her needs. It had started off as really annoying, but it had slowly morphed into something that she thought was endearing. His cheesy jokes and ridiculous puns always brightened her day; he was such a child. But, on the other side of that coin, he was also a very intelligent and percetive boy. He always noticed things and solved problems that others couldn't. He was truly brilliant.

And, just like every friend she had, he had taken over part of her heart.

Marinette giggled as she pulled out her phone and sent him a quick text, which he would recieve moments later upon his awakening. And Adrien would stare at it with a large grin and feel bubbles inside his chest.

Have a wonderful day, Chat. 3 ;)
