Welcome to the third chapter of Chat Chanceux. If you didn't know, his name translates to Lucky Cat. I guess the Agreste boys just had to have Cat named alter-egos.

The group stood awkwardly near the gates of the school, the student body whispering as they stared and walked past. Obvious whispering and pointing at the odd sight of a tall blond man holding Marinette in his arm like it was the most natural thing in the world.

"Hey, guys, not that I don't think that this reunion isn't cool or anything but maybe we shouldn't do it somewhere so… Open?" Nino spoke up, arm linked with his girlfriend who was intensely watching the interaction between the Agreste brothers and tiny Marinette between them.

"We could go to my house? Since it's the closest?" Marinette offered.

"Are you certain that your parents would not mind?" Felix asked gently, trying to hide the excitement in his voice. Marinette only giggled and led him away towards her home.

She watched as Felix perked up, his stern eyes widened slightly and his mouth twitched., suppressing a smile. Marinette smiled knowingly. It was nice being able to see such quirks so clearly on her friend's face instead of trying to spot them through the grainy computer screen. The group agreed and they made their way in the general direction of the bakery.

Nino and Alya taking up the front, animatedly discussing Ladybug and Chat Noir's latest escapades, while Adrien stood in the middle of the group, his attention divided between listening more about his favorite Lady or to actually observe the curious behavior of his brother. Marinette and Felix bringing up the back of the group. Felix seemed reluctant to release Marinette from his hold. He had taken her school bag from Alya while Marinette held on to the bouquet Felix had gotten her.

Adrien couldn't help but try sneaking looks at his brother and one of his friends being so… close to each other. He had never seen Marinette so at peace. Well, not around him at least. Her clumsiness and quirky babbling whenever she was nervous (which always seemed to multiply tenfold whenever he was around), while endearing had made him feel like she had still disliked him because of the 'Gum Incident' from when he had first started school. But later on he understood that Marinette was simply shy around him.

Probably because he was the son of her favorite fashion designer. Yeah, that's probably why she was so flustered around him.

"You know this will be the first time you'll actually be in my home Chat." Marinette mused out loud.

"I have seen it plenty of times in photographs and through our video calls, but I am looking forward to seeing in person," Felix replied, catching Marinette's gaze and giving her a playful wink.

Marinette couldn't stop herself from looking at her friend, taking in his appearance and mannerisms. He had seemed like the kind of person to always want to keep his emotions in check, choosing every word carefully before he actually said them out loud. Yet whenever he was with her, he had an easygoing air around him. Like as if he could finally relax and be himself. No fear of judgment or harsh reprimand. At first, she had guessed it was his family's prestigious background, but now… Now she knew it was from the strict parenting of Gabriel Agreste that forced him to keep himself so tightly reigned and his emotions so guarded.

What had Felix been like before the death of his Mother? She had always mused over Adrien's childhood while he was being homeschooled. She had wasted many an afternoon dreaming of a blond toddler with emerald green eyes and a toothy smile. Felix had never mentioned being homeschooled. The differences between the brothers poked at her curious nature. She observed as Felix walked proudly, back straight and shoulders back. His stride matched hers, he didn't look bothered by the fact that he had her pink book bag slung over one shoulder.

"If I had known I would be going to your home, I would have brought some flowers for your mother as well." Felix pointed out to her. Marinette rolled her eyes.

"You can just give her these ones." Marinette gestured the bouquet in her hand.

"Do not be silly, Mari. Those are for you." Felix rebutted.

"You can always get me more. Can't you Mr. Rich Boy." Marinette teased.

"I suppose I could. I might be able to get one that would better match your room decor." Felix smirked knowingly.

Marinette gasped, stopping right in her tracks.

Her room.

Her room that had Adrien's face plastered on almost every available surface area.

Oh no. She pushed the bouquet into Felix's hands while snatching her book bag from Felix's shoulder and dashed forward, grabbing Alya's hand and pulling her best friend along.

"Sorry boys, I need to get something done real quick before you come over. So take your time. See you!" She explained as she ran ahead while Alya laughed, following behind.

The three boys left behind could only stare as the two girls disappeared into the bakery. Watching as a surprised Mme Dupain-Cheng step out of the way of the force that was Marinette and Alya. Mme Dupain-Cheng waved at the boys when she caught them staring. Eyes widened and mouth forming a perfect 'O' when she locked eyes with Felix. She hurried to the door and opened it for the boys.

"Boys! Welcome! How are you?" She asked, her eyes zeroed in on Felix in particular.

"Hey Mme Dupain-Cheng, we're good." Nino greeted casually.

"Hello Madame, it is nice to finally meet you. These are for you." Felix presented the bouquet he had originally gotten for Marinette to the short Chinese woman. She gave him a once-over, obviously recognizing him from her daughter's many skype calls and pulled him down for a quick hug. Nino snickered while Adrien observed the exchange in bewilderment.

"These are lovely dear. I'll put them in a vase. Tom is in the back, why don't you join him. I'm sure he would love to catch up." Mme Dupain-Cheng gestured to the back door that leads to the kitchen. It also leads to the house that the family took residence in above the bakery.

While the boys spent some time conversing with the large baker, Marinette frantically removed her pinned up posters of Adrien that was on her walls. Keeping them in a file so that she could put them up again later. Alya helped her to remove the standee with Adrien's schedule pinned.

The girls heard a knock on the trap door that leads to Marinette's room and Mme Dupain-Cheng's head popped through.

"The boys are with your father but I don't think they'll take more than 5 minutes." Sabine warned her daughter.

"We'll be done by then, could you send them up when Papa is done with them?" Marinette pleaded.

"Of course, ma fille."

"Merci, Maman. J'apprécie" Marinette blushed as she tried not to rip a particularly stubborn poster from its spot on her wall. She heard her mother's soft laugh as the trapdoor closed.

"Girl, you never told me Chat Chanceux was brothers with Adrien." Alya started the moment they heard Mme Dupain-Cheng's footsteps fade away.

"That's because I never knew!" Marinette moaned. Alya sat on the chaise, her back to Marinette while she checked her phone. Marinette took the opportunity to let Tikki out from the confines of her bag. The small God flew out and up towards Marinette's loft to rest.

After the last poster was taken down and safely tucked away into the file, Marinette flopped onto the floor next to Alya, leaning against her best friend's legs. Her heart was still thundering in her chest from the sudden cardio.

A knock came from the trapdoor and it opened to reveal Nino.

"Is the coast clear?" He asked with a smile.

"Yeap, no incriminating evidence of a robbery lying around. You're all safe from being caught as our co-conspirators." Alya replied, gesturing her boyfriend to come over with a wiggle of her finger.

Marinette was fascinated while she watched Felix climb up into her room holding a plate of snacks that her Papa had given him to bring up for the group to share. This was actually happening. Her best friend was finally in the same room as her. He was actually here in person and not just observing his surrounding through the screen of her computer.

Marinette's breath caught in her throat as Adrien's head appeared and he smiled at her. She could feel her cheeks turn pink at that small gesture. She really was hopeless when it came to Adrien. Felix nudged her as he took a seat next to her. Marinette flushed and smiled in apology to him.

Adrien took a seat at the computer since it was the only available chair. Nino and Alya taking the chaise while Marinette and his brother sat on the floor at their feet. Adrien took note of how Felix had immediately gone to sit by Marinette's side. Were those two dating? The thought made his chest clench uneasily as he watched over the two of them.

"So Felix, are you and Marinette a thing?" Nino asked curiously.

Marinette spluttered and immediately pushed herself away from Felix and flushed a bright red. She ended up clutching a cushion from the chaise and sat on the floor, positioned between Felix and Adrien. Felix's eyes narrowed at the distance between them. He subtly shifted, so that he sat away from Alya and Nino, nearer to Marinette.

"We are not." Felix replied easily, unbothered by the rather straightforward question.

"Seriously dude? But you two were literally wrapped around each earlier." Nino pressed on watching as Felix continued to scoot his butt across the floor to get closer to Marinette.

"W-we… Well ...We're not like that.. I mean, that is to say, it's not like we're together, i mean we're not. But we're not together-together. We're just super close. But like not in a couple kind of way. Not that it's bad for couples to be close. I mean you and Alya are fine. It's sweet how close the two of you are. Me and Chat are close too. But not the same way-" Marinette desperately tried to explain the situation before Felix interrupted her.

"What Marinette means to say is that the two of us are very close because we've been friends for so long. Longer than even Alya has known Marinette." Felix easily explained.

"The two of them have been pen-pals for the past 4 years." Alya added in.

Adrien let out the breath that he hadn't known that he was holding. So the two of them weren't dating each other. But it was still curious how close they were with each other. As far as he knew, his brother had been sent away to study in a prestigious school for highly intelligent teens in London. He had read through the curriculum, while Adrien was ahead of his classmates and maintained his straight A's, Felix's classes seemed infinitely harder, covering topics Adrien could only hope to comprehend. When did Felix have the time to maintain a friendship?

Both Felix and Marinette ended up spending the afternoon explaining the origin of their friendship. Alya and Nino joined in the conversation, sharing how they knew Marinette, Adrien joining in as well sharing his own experience. Felix only smiled knowingly when his younger brother described the 'Gum Incident' with a shy smile and a hand cupping the back of his neck. Marinette already red from remembering her uncharacteristic outburst. Felix simply comforted her by rubbing circles on her back in an attempt to calm her down.

"You know, I had always wanted to be able to comfort you like this. Soothing words from across a keyboard simply didn't feel right." Felix whispered, almost reverently. Marinette stared at him for a long moment. The conversation around them seemed to have died down as the others waited for Marinette's reply.

"I've always wanted to be able to comfort you too, Chat." Marinette whispered. She took his hand in hers and set them on her lap. Leaning against him in an effort to emphasize to him that she was there.

She was there, and she wasn't going to leave anytime soon. It must have been so difficult for him to be away from his family for so long. In an environment that he couldn't even make friends with his classmates. She couldn't begin to imagine how lonely he might have been. Marinette squeezed his hand, he had her now. She would never allow him to feel lonely again.

Adrien coughed into his fist in an attempt to disperse the intense atmosphere. Marinette and his brother certainly seemed to be very close. Checking the time, he realized that he had to go for his Chinese lessons. He stood up and started making his excuses.

"Felix, would you like a ride home?" Adrien offered. He couldn't help but notice the look of disappointment that crossed Marinette's sweet face at the thought of his brother leaving so soon. His chest clenched painfully again.

Marinette used to have the same look whenever it was Adrien who had to leave early. Now it seemed that his friend only had eyes for his brother.

"That would not be necessary, frère. I have rented out my own apartment. I will be able to commute on my own without much is actually not too far from here." Felix explained.

Adrien couldn't help but let his jaw drop when he heard the news.

"You rented out your own apartment? In Paris? By yourself? Isn't that expensive?" Alya questioned eagerly.

"Mlle Alya, I am a graduate from a prestigious school who has been investing his allowance on foreign stock markets over the entire duration while I was away. I am more than able to provide for myself now that I am no longer dependent on my father or his name." Felix answered as if it was simply no big deal. Marinette gaped at him in shock.

An impatient honking startled the group and Adrien made his excuses to leave. Marinette stood up and offered to walk him out, Adrien accepting with a bright smile. As the door closed after them, Marinette took the time to observe Adrien. Felix and Adrien didn't look exactly alike but there was still the family resemblance. They both had the high cheekbones and sharp nose. Felix had a stronger jaw compared to Adrien. Adrien had their Mother's almond-shaped eyes the color of emeralds, while Felix had their Father's deep-set blue-grey irises.

"So you and my brother seem pretty close." Adrien broke the silence.

"Uhm.. yeah?" Marinette sheepishly answered. "It's not weird for you or anything right? I mean I wouldn't want to make you feel uncomfortable since I'm apparently best friends with your older brother. But this was even before I knew that he was your brother. I'm friends with him because I like him." Marinette blushed at her words. "Not the like-like kind of like! The like you as a friend kind of like. He's a really good friend and he's nice to me and really, I honestly wouldn't know what to do if my friendship with him makes you uncomfortable." Marinette mumbled towards the end, cheeks pink in embarrassment.

"To be honest, I was kind of shocked because Felix never told me that he was coming home. Seeing him for the first time since I've visited him for the holidays was kind of a shock, considering he was wrapped up around you." Adrien admitted, hand going to the back of his neck in an attempt to appear casual.

Marinette tried to respond her mouth opening and closing to make words, but nothing would come out, leaving her looking like a gaping fish.

Was it just me or was Adrien...Jealous?

The Gorilla started pressing down on the car horn once again when he spotted Adrien through the store windows. Adrien waved at him in an attempt to placate the surly man. Adrien opened the door and turned back to bid Marinette goodbye, kissing her cheek before gently shutting the door behind him.

Marinette slapped a hand to her cheek, pink cheeks turning bright red as she watched Adrien be driven away. Did he just?

Sabine watched with a smile from behind the counter as her daughter walked her crush out of the door. The two of them definitely looked sweet together. It had been a welcomed surprise to see Chat Chanceux in her bakery. It was an even bigger surprise to find out that Chat Chanceux was actually Adrien Agreste's older brother Felix.

It was nice to see her daughter who was not tongue-tied in front of a member of the Agreste family. That is until Adrien Agreste kissed Marinette on her cheek.

Oh dear.

She watched helplessly as her daughter stumbled back, face red and eyes wide as the young Agreste boy drove away. None the wiser of the turmoil he had left behind in her daughter's heart.

Thank you for reading this story! To be honest I have no idea what I'm doing or where this plot is going but hopefully, it'll be good.
