AN: hey guys, here is my new ten-chapter work. Updates daily or once in two days. Also thanks a lot to amazing Su'anne for her hard beta work! Enjoy and leave your thoughts!;)

Louis considered himself a happy boy and a good son and brother. Well, no one could argue about that.

Louis was fifteen, had two slightly younger siblings - Emma and Hugo, loving parents and if asked what would he wanted to change, the answer would be "nothing".

But, you know, things never go as wanted.

It was early autumn in Paris, and the city was quiet. Akuma attacks stopped 20 years ago, when Ladybug and Chat Noir defeated Hawkmoth. So Louis was clearly confused when the light of what could only be described as miraculous-related (or what he seen it looked like from famous Ladyblog) enveloped him.

At first it was purple darkness everywhere, then as suddenly as it started, the magic around faded. Louis winced expectantly, but nothing happened, so he opened his eyes.

He was in the same place where the miraculous magic reached him, except he wasn't. If that made any sense.

The surroundings were only nearly familiar, and instead of a quiet empty street Louis was met with battle sounds and screams and -... Oh god, it's an akuma attack, he realized in panic.

The akumatized victim appeared out of nowhere right in front of him. Louis was a brave boy, he knew martial arts and self-defense, but as far as he remembered, even trained civilians could do nothing against akumas, only distract them for the superheroes.

Wow, realized Louis, it means I'm gonna meet the real Ladybug and Chat Noir! Or whoever the superheroes will be this time.

"I'm Time Master!" suddenly yelled the akuma. Louis froze on the spot and looked at the victim. "They said I can't rule the timeline, I'll prove them otherwise! Ladybug and Chat Noir, give me your miraculous or else I'll use this boy as a revenge! Nobody knows how time traveling affects the events in future, so we'll see how it goes!"

The akuma laughed evilly and disappeared in a cloud of white sparkles. Louis still stood at the same place like a deer caught in headlights. However, while his body was still, his mind was working quickly.

The boy felt sick. Use him as revenge? I'm too young to die, screamed his mind. 'Time traveling' was the second thing that registered. The akuma said time traveling, he thought, and we know that those evil beings existed only in the past. That means that most likely I'm at least 20 years back in the past. For this also speaks something about affecting events in the future... Oh god.

Louis realized with growing horror that all his actions will somehow affect his own time. But, he reasoned himself, if miraculous cure, the most valuable Ladybug's power, will work alright, nothing would be changed. Hopefully. What if something goes wrong? his mind screamed in panic. What if...

His thoughts were interrupted by real superheroes landing in front of him. They indeed were Ladybug and Chat Noir somewhat younger than they were when they defeated Hawkmoth.

"Hey, did you see where..." started Ladybug, only to be interrupted by delighted squeal.

"Wow, oh my gosh, real superheroes! Punch me, I must be dreaming! No one is going to believe me!" Louis, who never saw superheroes in his entire life, was on the edge of the excitement.

Ladybug and Chat Noir exchanged a confused look. Louis saw the misunderstanding crossing their faces and hurried to explain.

"Oh, um, sorry, we in our time don't have superheroes, so it's kinda... exciting?! Aaaand, the akuma just disappeared in the, um, white sparkles? Like, dissipated in the air?"

The duo simultaneously raised their eyebrows. Chat Noir was the first to speak back.

"In your time? What do you mean, you were brought here by the akuma?"

"Yeah!" exclaimed Louis. "At least it looks like that. I was walking home, then this miraculous-related light surrounded me, and puff! I'm here. The akuma said that he wanted to see how will the future be affected and maybe he just chose me randomly? At least I don't know the reason why me."

"I see..." hummed Ladybug. "Looks like that. What year is it in your time?"

"2039. I suppose here it's 2019 or a little bit earlier, right?"

The lucky duo exchanged a look.

"It's 2016," answered Chat Noir, "any reason why did you think about this year?"

"Um, you guys defeated Hawkmoth in 2019 and the evil was stopped. After that you retired and took patrols for only a year after that. And you look a bit younger than when it happened. In my time there are no akumas or superheroes, only Ladyblog as the source of information about what Paris was like in these times."

Ladybug and Chat Noir flashed each other a smile. Good to know they could stop evil in the future.

"Can you tell us a little bit more about yourself and maybe about your time?" asked Ladybug cautiously. Could you blame her for being curious?

"Sure thing, lady," beamed Louis. "My name is Louis, by the way. About you we know that no one knows your civilian selves, only you two. No one knows who Hawkmoth was, either. That's from important. About me, I have two younger siblings, Emma and Hugo, and... Oh god!" he exclaimed. "My parents would be so worried!"

Ladybug listened Louis attentively. So she and Chat would reveal themselves to each other in the end. And - Louis, Emma and Hugo? That's how she wanted to name her children with Adrien! She could understand that two names were the coincidence, but all three?! Also, she reasoned, the akuma must have had REASONS to pick exactly this boy from exactly this time. What confused her was the fact that Louis seemed completely unaware of her civilian identity. He even called her 'lady'! She would have told her children about this, right? Oh no, she thought, what if I never told Adrien in future that I'm Ladybug? It means that I'm constantly lying to him!

"Your parents must be indeed worried, we'll try to defeat Time Master as quickly as possible so you can return," Chat Noir's voice reached Ladybug. She looked at Louis attentively for the first time.

The boy had blond hair, several shades darker than Adrien's. Blue-grey eyes suited him perfectly. Ladybug could see noticeable resemblance now between Louis and Adrien. She counted the years. They must have been twenty three years old back in future when Louis was born. There was a real chance...

"Louis," she called him. The boy turned to her with an excited expression. Ladybug swallowed the ball in her throat before asking. "Is your last name Agreste?" Please, say yes, she begged internally.

Louis looked at her with an amused expression. Chat held his breath, but no one noticed.

"Yes, it is. How did you know, lady?"

Ladybug jumped high, fist pumping in the air with a faint 'yes!'. Chat Noir made a strange sound in surprise. Louis looked at the pair of superheroes with a lifted eyebrow.

"What's up with this reaction? Does that change things?"

"Wait, do you know who I am?" asked Ladybug and Chat Noir in unison. The boy obviously didn't know who they were, how do you like it? Superheroes shared a confused look between each other.

"No. Should I? I told you no one knows who you are in my time, and I'm no exception..."

"Never mind," waved off Ladybug. "I think what, Louis Agreste," she lit up while pronouncing his name. "If Time Master disappeared now, it will take us significantly longer to find and defeat him. I'm afraid you have to stay here for a while. I would have proposed to go to your father's house, but as far as I know it would be quite complicated. So why don't you go to your mother's? Maybe you also should enter her school. Who knows, maybe it would be helpful." Ladybug finished and flashed him a bright smile.

"Thanks, lady, I will," replied amused Louis. 'Lady' was becoming a thing, huh? "I take that you know who my mother is, don't you?"

"I think I might have an idea," smiled the superheroine.

"What's your mother's name?" asked Chat Noir cautiously.

"Marinette," smiled Louis.

Chat stiffened. There are many Marinettes in Paris, he reasoned himself. His lady's name could easily be Marinette, after all.

"So your parents are..." Chat didn't dare to finish the statement.

"Adrien and Marinette Agreste. Her maiden name was... Dupain-Cheng, if I recall correctly."

Ladybug squealed in delight, while Chat felt like all the air was knocked out of his lungs. It's not that he didn't like Marinette, he just hoped he would end up with Ladybug. And, of course, his lady's reaction didn't go unnoticed by him.

"Why are you so happy about this fact?" snapped Chat.

"Ohhh, it's all I ever wanted for Marinette!" smiled Ladybug back. The excuse could pass, right? Nothing special about the fact she knew Marinette. "Aren't you?"

"I was hoping for the other scenario concerning the Agreste boy," replied Chat with a dejected sigh. Ladybug put a comforting hand on his shoulder. Which exactly? she wanted to ask. Even though Ladybug now knew they would be together, she couldn't help but feel a twinkle of jealousy. Chat wanted Adrien for someone else?

"For the record," interjected Louis, "father is more passionate about my mother than she is. He basically worships her. She is the rational one at this point. Though they equally love each other and have all these weird nicknames..."

"That can't be," chorused the duo, confusion once again on their faces.

"Yet it IS so and I can't understand you two. Hey, umm, Ladybug? What do I tell Marinette?"

"The truth," she shrugged in response, still shocked at Louis's words. Chat's blood ran cold. Marinette would know about their future children?! He had a feeling that there was something important that he wasn't catching. But the feline superhero said nothing.

Their miraculous beeped in warning, and the three of them parted their ways a minute after.

To tell the truth, Louis was scared. Scared that his mom won't accept him. Scared to make mistakes that could affect his present. What if Marinette won't believe him? What if he would be left alone in the street? And one thing was explaining everything to his mother, while the other was deciding whether or not to tell his father or anyone else at that point.

Louis reached his grandparents' bakery and stopped at the opposite side of the road. It was 23 years in the future since he last was there! The thought made his head spin. How crazy was all that?

A dark-haired girl left the bakery, and Louis realized in several moments it was his mom. Marinette Agreste. No, Dupain-Cheng. She is so young that it seems wrong and surreal on so many levels, thought the boy.

"Mo-Marinette!" called Louis, catching himself at the last moment. Calling her mom would be... complicated.

Marinette turned around to face Louis. His breath caught in the throat. God, help me, he begged. His mom was heading towards him, Louis realized in panic.

"Do we know each other?" Marinette asked with a hint of smile. Oh, she couldn't take the chance to hear an explanation from her son. And considering that he had no idea she was Ladybug, she had no right to give her identity away.

"Y-yes... No? Umm, it's c-complicated?" stuttered Louis. Marinette raised an eyebrow.

"I'm not quite following you here..."

"Um, there was a-an akuma attack? Akuma is Time Master, but Ladybug and Chat Noir didn't catch him yet, he just disappeared. Time Master, um, he, uhh, brought me here?"

"Brought you here from where?"

"Umm... From future?"

"...And?.."

"Marinette... Will you believe me? Please do."

She internally giggled at his insecurity. But how could she blame him? You don't end up every day introducing yourself to your parents.

"Okay, I heard about Time Master and, to tell the truth, there is hardly anything unbelievable since we have superheroes and supervillians and all this weird stuff. So I think I can believe you."

"Oh, um, thanks? I - see, I'm, uhh..."

"Yes?.." kindly prompted his mother. Louis took in a deep breath. It was now or never.

"My name is Louis. It's 2039 in my present, which sends us 23 years in the future. I have two younger siblings, Emma and Hugo, and my parents are Adrien and Marinette Agreste. Hi, mom," he finished with loud exhale and looked worriedly at the girl before him.

Marinette stood there with her mouth hanging open (a bit of acting won't hurt, right?). Noticing Louis's gaze, she closed her mouth and swallowed hard. The girl slightly tilted her head to the side, observing Louis. Then she came closer and slowly made a circle around him, observing the boy from each angle. He was nearly Adrien's height, had broad toned shoulders and athletic figure all in all. Marinette carefully put a hand on his cheek. She traced her fingers lightly across his features, then tangled them in his hair. Louis stood still on the spot, patiently waiting for his mother to finish the observation.

Now, taking a second look at Louis, Marinette could see both hers and Adrien's features in their son. It still felt too good and too surreal to be true. She leaned in and kissed the boy's cheek.

"I believe you," she finally said. "Not only because I can see the resemblance, but mostly because you wouldn't want to lie about such thing. Moreover, I always wanted to name my children with Adrien Louis, Emma and Hugo."

"Thanks, mom, you're the best," smiled Louis in relief.

"Come on, Louis Agreste," he didn't miss the pleasure in her voice when she called him by his name. "Let's go and find you a place to stay in the bakery. We're extremely lucky that my parents just left for a two-week family trip to China. So there won't be any complications, hopefully."

It was Sunday morning, and the two of them had some time to find Louis some clothes, think up of a story and talk a little bit more.

"So," summed up Marinette, "you're a new student, who was forced to change a school after moving to the new apartment. Since you have documents as Louis Agreste, we need... somehow... to warn Adrien? Maybe you could pass as his cousin? Oh, who am I kidding? He's like, a famous model, anyone can tell he doesn't have a cousin named Louis!"

"Hey, mom," Louis tried to calm her down, "maybe we could say that we're not related, just have the same last name? It's not hard to believe, since it's pretty normal situation. Yet I think we should tell him."

"Are you crazy?! He'll think I'm a freak, you're a freak, ignore us and call an ambulance! We'll end up in psychiatric hospital for the rest of our lives and you'll never exist!"

Louis chuckled at his mother's panic mode.

"Besides," continued Marinette, "he doesn't love me now. He can take it really badly. So let's keep silent about it, will we?"

Well, she had a point here.

"Okay."

Only later, drifting off to sleep, the realization sank in Marinette's mind. She and Adrien will marry and live happily ever after, and he will love her with all his heart! They will have three children and a hamster! ...A hamster?

"Hey, Louis..."

"Yes, mom?"

"Do we have a hamster?"

The boy giggled. His mother really had it all planned ahead.

"Two hamsters, actually. You and dad named them Plagg and Tikki."

Oh my gosh, thought Marinette, the older me is desperate enough to name a freaking hamster after my beloved kwami.
