A/N: Hey guys! This is my first Miraculous fanfic and I would really appreciate any feedback for it, especially since I'm kinda new to the fandom and all. This will be Adrien x Marinette, although Félix will play an important role in it. I'm open to ideas and any support you're willing to give me.

Prologue

„Caught you, you little thief!"

Félix froze in his tracks. He had never expected to be caught. For a single moment, he considered pretending innocent, but once he saw the look in the woman's eyes, he knew there was no point. Finally, he sighed.

"Fine, you woman," he drawled lazily. He got out his wallet. "I'll pay. How much was it? Three euros? Four?" He got out a five-euro note and threw it at her. The woman's eyes narrowed.

"Oh, you think you're getting out of this, don't you?" She raised the broom that she had been hiding behind her back. Alarmed, Félix tried to open the door but it wouldn't budge. The woman cackled, bringing the broom down. It hit emptiness, as the blonde boy managed to dodge it just in time. But the owner of the establishment wasn't that fickle. She spun around and hissed at Félix, trying to hit him again. Who cares if some of the merchandise got destroyed in the process? That was life. Teaching this imp a lesson was important.

The boy dodged, a wicked smirk appearing on his face. This was fun. He could evade this witch for a while.

Another shelf fell, victim to the woman's broomstick. Chocolates came tumbling down and he almost slipped on a puff pastry, when he stepped into it. Félix cursed. The cream had stained his perfect shoes. It was in that moment that the broom finally hit its target.

"Ha! Gotcha!" cheered the woman. "Take that! Now I've got you, Félix Graham de Vanily!"

A chill ran down his spine. He was cornered. The sudden panic on his face made the woman lower her broom. How did she know his name even?

"My name is Marie," she offered her hand after a small pause. Félix accepted it cautiously. "Your actions are quite punishable and I'm not letting you off easy." Marie pulled him along to the counter, as she got behind it.

"Three bonbons, two truffles and four carefully crafted pralines. Plus thievery tax." she entered into the register. Félix picked his wallet up from the rubble. "And that's only this week. That comes up to…" she looked at the numbers. "13 euros and three acts of kindness."

Félix counted the money. "13 euros and… what was that?"

"Three acts of kindness." Marie smiled sweetly. She poked his chest with a pointed finger. "And mind you, they must come from your heart." She pulled the receipt from the printer and passed it to the blonde boy, so he could see for himself. As Marie put away the money, the words on the paper in his hand faded. He raised an eyebrow.

"And if you don't," Marie's smile turned into a frightening grin. "There will be a price to pay. You will lose something important to you. And to ensure you complete your tasks, you will be plagued by bad luck until you do." Immediately upon hearing these words, Félix scoffed, even though a number of things ran through his head. Clearly, this woman was barmy.

This time, when he tried to leave, the door opened easily. It closed behind him with a loud bang, as he stuffed the receipt in his pocket. Three acts of kindness indeed. He had no intention of carrying these out.

Inside, Marie laughed heartily. "What a young man you've grown into, Félix," she murmured to herself. She looked at the mess and sighed heavily, grabbing her broom again. "Your father would be greatly disappointed." She began to sweep, whistling a melancholic tune.

"You can come out now, Choccolat," she spoke to the empty room. A dark-brown kwami flew through the closed back door.

"Think this will work?" she snarled. Marie laughed heartily at the frown on Choccolat's face.

"We can only hope," she answered softly. "I owe it to his father."

"His father is dead," shrugged the kwami. She flew over to the shelf where bonbons were placed in a neat row and picked one up. It was heavy enough to hold, but she bit into it mid-flight nevertheless, not bothering to wait until she could safely land.

"Even more the reason to set his kid straight," Marie argued. "Wasn't it lucky that he came here?"

"He's lucky I didn't bite his thieving fingers off," huffed the kwami between bites. "How dare he come here and steal my precious chocolate."

"Oh, it's alright, isn't it?" The woman put the broom away and locked the front door. "We're only here for a moment anyway."

"Oh, please don't start!" Choccolat groaned. "I already promised you I won't bail on you like that again! Don't give me away!" Tiny tears appeared in her eyes, threatening to spill. "I'll do anything you want! Just don't condemn me into that boring existence in that damn box!"

Marie twirled the ring around her finger. It was golden like a chocolate wrapper, perfect for the kwami residing in it. She played around with the idea of removing it and making the annoying, but lovable creature disappear. In the end, she kept it on.

"The world needs true love." She patted Choccolat affectionately. "I'm sure there's another worthy holder for you out there."

"I don't want a new holder." the kwami sniffled. "You're my holder."

"Oh, sweetie," Marie shushed her, offering her a piece of chocolate. "You know as well as I do that my time is coming to a close." Choccolat devoured the sweet and flew close to her owner's face. She placed two small hands on it. A loud smooch accompanied the kiss she planted on her cheek.

"Ew! Choccolat!" exclaimed the woman, touching her cheek and feeling the melted chocolate on it. "You're disgusting, you know that?" She wiped her cheek with a sleeve.

Chocolat made a tour around her head, before announcing loudly: "You love me anyway."
