Author's Note: Hey guys! So this idea came to me after skimming through the Ml fandom so I decided to write it! I'm not abandoning my other stories; they're still coming so this is just something for fun. Let's get going!

Summary: Cold weather comes to Paris but that means bad weather for Adrien who had already caught a cold. Lucky for Mari when she took this opportunity to take care of him and to get closer of course; unfortunately, Chloe had to jump in. But things gets worse when an enemy with the power of ice and snow comes and starts wreaking havoc, this proves to be difficult for Mari.

Chapter 1: Oh those cold blues

A heavy groan came before a stuffed sniff came along. Adrien open his eyes and his world felt like spinning. The minute he opened his eyes, he was instantly met with his head throbbing and his nose stuffed, making it difficult for him to breathe. Right there and then, Adrien knew this was going to be a dreadful day; his father would probably make him go to school, however.

His stomach churned, having the feeling that he felt like throwing up. His eyes were heavy with fatigue, his body weak and he felt like he couldn't do anything. Just from that thought, Adrien instantly went back to his previous fight which was yesterday. An employee from the Aquarius decided that he lacked faith in himself, to put it short, and naturally, he was akumatized, granting him the power of water.

Adrien, as Chat Noir, naturally got dunked into the depths of the water making his partner in crime pull him out and had purified the enemy back to his normal state. And as the saying goes, "cats hate water".

The blonde boy groaned again, feeling his forehead burning as his headache continued to throb.

This was so not his day. And it also came to a conclusion.

Adrien Agreste is sick.

Dragging himself out, Adrien got out of bed and stumbled forward, desperately trying to grab on some clothes. He did so but not in a clean way. With dull eyes, Adrien pushed open his door to go to the bathroom, using his head to rub his nose. He gradually made his way to the bathroom and faced the mirror, only he wished he hadn't.

The moment he looked into the mirror, he wanted to run away and hide himself in his bed; he literally looked like death itself.

As he grabbed his toothbrush, a small pet zipped out of Adrien's pocket from his vest and with a cheerful look, he shouted.

"Goooood mooooorningggg, Par-what in the cheese name?!" Plagg, the black Kwami shrieked which made Adrien raise a dull eyebrow.

"Wh...what happened to you lad? You look like death itself."

"Gee, thanks." Adrien muttered, flatly.

"No problem!" he chirped before taking out a piece of cheese, hugging it as he took in the aroma. "Hmmm...the smell of cheese. Just smell the divine aroma."

He practically shoved the cheese into Adrien's face and as a response, Adrien tried not to gag.

Scowling, Plagg pulled back the cheese and rubbed against him.

"Its okay, my lovable cheese. I'm your one true love." with that, Plagg swallowed the food down in one piece and let out a satisfying burp.

Adrien made a flat look. "You're disgusting."

Plagg took at the hero's look. "Takes one to know one!" he laughed before he got swooped in a Ziploc bag, being shoved in one of the bathroom drawers.

"Adriennnnnn! LEMME OUTTA HEREEE! ADRIENNNNN!"

Marinette yawned. Fighting that water bender enemy really took a toll on her. Not too mention she too had to rescue her partner. She just hoped that he ended up alright.

"Bonjour, Marinette."

The raven-haired girl turned to the side and smiles seeing her brunette friend that was known as Alya.

"Hey, Alya."

"Hey, girl." she paused. "You look really tired."

"Oh uh...I stayed up late, making a new fashion design." she lied, casually.

She seemed to buy it. "I bet Adrien would love it." she teased.

Mari blushed as they started to walk towards the entrance. She gave a glance around the area, looking for a certain blonde boy.

"Already, looking for him?" Alya laughed. "Mari, you're so predictable!"

"I can't help it!" she said, sheepishly.

Just then, a black limo pulled up at the entrance of which caught their attention.

"Much to your luck." Alya nudged her, winking.

The door opened and Mari's heart started to thump wildly; her crush was about to make an appearance and naturally she would start drooling over how handsome he is, the hotness, those perfect features-

"What the-"

Mari's daydream crashed down when Alya's voice bought her back to reality. Alya and Mari gaped at Adrien as he walked up to the front; he really looked like a mess.

His usual combed hair was messy and went in almost every direction; his eyes were drooping and his cheeks were flushed.

Mari opened and closed her mouth several of times before Adrien stopped by them.

"Hey." he responded with a stuffed voice.

"What...what happened to you?" Alya asked, flabbergasted.

"I ged 'ick."

"Ick?" Mari said, blankly.

"No, 'ick." the poor boy tried again.

Again, no response.

Adrien sighed. However, the limo didn't pulled away as the door opened again to reveal a lady in a bun with glasses. Her body told people that she held strictness.

"Adrien."

"Who's she?" Mari asked.

"'athalie." he replied, stuffly.

"..."

"I had just been known that you were sick."

The two girls gasped but much to their dismay, another voice tagged along.

"My Adrien got sick!? Oh my poor baby! Come to Chloe! I'll take care of you!" Chloe replied, jumping at the opportunity. Poor Adrien tried to refuse but Chloe took the wrong way.

"Ahem." the stern voice of Natalie simply told Chloe to get off. "As I was saying, you're sick. And your father forbids you to go to school. But seeing as both his and mine schedule are going to be busy, I won't be available to take care of you. Therefore, there will be a person taking care of you."

"Dho?"

Natasha simply ignored the frantic wave of Chloe and she stared at Mari.

"Her."

Mari and Chloe gasped; Mari from shock and Chloe from disbelief. Of course, Chloe fainted into Sabrina's arms.

"Me?!" Mari sputtered. "But school...parents..."

"Do not worry. That will be taken care of. Your parent will be alerted of the situation and the homework will be send to you." she then turned to Adrien. "Now, come."

Adrien sighed. "Yes, 'Astha."

Gloomily, Adrien walked back to the limo while Mari stood there, eyes wide and her mouth opene.

Alya noticed and tried not to laugh. "Go. You'll be fine."

"B-but..."

"Go. They're waiting for you."

With a push, Mari walked ever so nervously towards the limo. Adrien slid to the empty side so that Mari could sit. As she got in, she gave a nervous laugh while Adrien gave a weak smile, almost as though he was apologizing for this unexpected task.

And then, the door was closed and the limo took off.

"Oooh! Why her?!" Chloe wailed. "I'll be a much better nurse than her." she sneered.

Alya smirked. "If I were you, I would quit while you're ahead. Wouldn't want you to die of embarrassment when you mess up, now would we?"

Chloe growled as Alya laughed. As she was gone, Chloe made a darkened face.

"That's right. Sit and laugh. Marinette better enjoy it because that would be the last day for her to be with Adrien."
