HI! This… is my first ever time writing for the Miraculous fandom, so I have no idea how this will go… ANYWAY, I'm gonna keep author's notes nice and simple (unless I have something to explain, which I don't exactly have at the moment), sooo happy reading!

(I don't own Miraculous)

Chapter 1 - Sleepless

Kwamis could sense if another was nearby, but that was as far as that power went. Sure, they could tell exactly which kwami it was, but never be able to identify the holder.

Tikki knew that since day one, all those years ago. But unlike her previous holder, who lived quite a distance away from their partner when they started their duties as a superhero, she knew that Plagg belonged to another student in Marinette's class. She just didn't know who.

It had bothered her for the past six months, and was frustrating to no end. Many a time had she wished that she was able to sense which student was the holder of the cat miraculous, and many a time she thought she'd finally figured it out. But each of those were eventually dismissed, after as little as an hour, depending on anything that was happening.

So, on a night where she for once couldn't sleep, Tikki slowly floated around Marinette's room in thought, thankful for the light of the full moon pouring through the window by the desk. She knew that going out to try and find Plagg was best to be done in the middle of the night, And since it was only half an hour ago that Marinette came back from her nightly patrol with Cat Noir, it was perfect timing.

There were some negatives of the idea. Hawk Moth had yet to strike in the dead of the night, and there was still little chance of it happening anyway. But Tikki still had no idea if it would ever happen, remembering that there were plenty of night attacks that'd happened over the past millennium or so. She didn't want to have to take chances, but also wanted to finally put her itching thoughts about where Plagg could be at ease.

Stopping by the desk window, she looked at it and contemplated just going out for a quick search when indistinct mumbling prompted her to fly back over to the bed. "Marinette?" she whispered, perching on the girl's knee.

"Tikki…" Marinette mumbled sleepily, rubbing her eyes. "Can't you… sleep?"

Tikki looked away for a few seconds, staring at the window again. "No," she replied, sighing. "For once," she added with a quiet giggle. "You…" she paused as she tried to gather her thoughts, "you… don't mind if I go out to try and find an old friend, do you?"

Blinking slowly, Marinette reached back to adjust her pillow before replying. "Not… not at all," she said, stifling a yawn. "Just… be back as… soon as possible?"

Tikki nodded and smiled, then looking to the window for a third time. "I hope he is out there," she muttered before zooming towards the window and phasing through it, squeaking as soon as a rush of cold air hit her. "I wonder if Marinette could try making a tiny jacket," she said to herself, shivering as she flew directly to the building directly opposite, from where she could easily spot a figure with unmistakeable cat ears still sitting on the roof of that building, just as a beep echoed out.

"One more minute…" she could hear him mutter.

Flying a little closer, Tikki stopped when she went over what Chat Noir had said in her head, confused for a second before realizing what he meant. "De-transform…" she muttered, looking back at the bakery. "This could be my chance… but… I must not tell Marinette."

So for an almost painful minute, Tikki sat on the edge of the chimney nearby, waiting for Chat Noir to change back to his civilian self. But, when that minute was almost up, he suddenly extended his staff and leapt down to the street on the other side of the building, a bright green flash lighting up the area just a few seconds after.

Tikki gasped and zoomed over to the other side, peeping over the guttering and looking down to the street, spotting a familiar, blond-haired boy standing under a lamppost. "Is that… Adrien?" Tikki quietly exclaimed, putting a tiny hand over her mouth. "Oh dear…" She sighed, giggling.

Down below, Plagg, who'd landed in a garbage can, groaned as he pushed the banana peel off of his head. "Geez, suicidal much, kid!" he grumbled, crossing his arms. "You owe me a lot of cheese for that."

"Plagg, come on, I wasn't thinking about it!" Adrien protested, glaring at the kwami as he bent down to re-tie his shoelaces. "I was just… thinking about Ladybug… and then I realized I wouldn't be able to get down."

Plagg only scoffed and rolled his eyes, then looking up as he suddenly saw a red blur fly across to the other building. "Tikki?" he muttered, cocking his head.

Finishing with his laces, Adrien stood up and looked over to Plagg, noticing that he was staring up at the building in front of them. "Come on, no time for stargazing, I've got a history test tomorrow," he said, walking over. "And… I hope Nino's still sleeping," he added in a quieter tone, looking to the side in worry. "Or if his brothers see that I'm gone…"

"Uh…" Plagg began, looking back down, "I… kinda saw a friend flying past," he replied, pointing up. "Ladybug's kwami. It's been a while," he explained quickly. "So… can I?"

Also looking up, Adrien tried to spot something whizzing past, but saw nothing, and presumed that the other kwami was out of sight. "Alright, I guess," he said, shrugging. "Just be back before morning, I've got extra camembert for your breakfast. You know where Nino's house is."

Eyes lighting up at the thought of extra camembert, Plagg nodded eagerly before zooming up to the top of the building, but to his surprise, he saw nothing. "Tikki?" he called out, looking around.

Several streets away, Tikki was speeding towards the Eiffel Tower, her mini mission accomplished, and wanting to just sit somewhere and enjoy the quiet night air for a few minutes. As soon as she got there, she went up to the lower viewing deck, seating herself on the edge of the railing. "This is going to be very hard to keep from Marinette," she said to herself, thinking about what happened earlier, then stopping in her thoughts. "It's been seventy-two years since I last saw Plagg, why didn't I stay behind to say hello?" she wondered aloud, sighing. "Maybe next time…"

After sitting there for ten minutes, Tikki considered going out to find Plagg again, but had second thoughts when snow started coming down. Looking up at the sky, she slowly lifted herself up and decided to head back home, suddenly starting to feel tiredness setting in as she got past the Trocadero. "I might be able to sleep now…" she mumbled, yawning as she reached the streets.

Having been zipping through the streets for the past ten minutes, Plagg eventually gave up on trying to find Tikki again, and grumbled when it started snowing. "Great," he muttered as the white flakes increased in numbers, rolling his eyes. "Whatever." He shrugged and turned back the way he came, yet stopping as he looked at the closest building, which was the bakery. "Huh, what's-her-name lives there," he remarked, flying closer to the top floor, almost immediately smelling something that had quite a distinct cookie tinge to it. "Maybe Tikki lives here too…" Frowning in thought, the kwami zoomed down to the bottom floor, phasing through the main door and entering the bakery.

And just as he did that, Tikki arrived at Marinette's balcony, quickly phasing through the hatch, sighing as soon as she got into the girl's warmer room. "That's better," she muttered, smiling. "Now…" she paused as she yawned for a third time, then floated around the bed, eventually noticing that Marinette was sound asleep, "where's the… old mitten?" she wondered, darting underneath the bed and spotting an old, pink woollen mitten lying on a white cushion. "That should be perfect," she said, slipping inside the mitten and lying down, not even noticing the small black thing whizzing into the room.

Plagg stopped by the chaise to look around for any signs of Tikki, pausing when he saw a half-eaten cookie on a smaller table, but dismissing it after a few seconds. "Meh, it's a bakery," he muttered, shrugging. "Of course it'll smell like cookies… but Tikki's still nearby…" Flying over to the window by the desk, Plagg immediately groaned as soon as he saw that the snow had picked up even more, along with the odd howling wind or two. "This was a bad idea," he said to himself, slapping his forehead in frustration. "Should have just gone back."

Now stuck in Marinette's room, Plagg looked around for somewhere to sleep, deciding that the cushions on the chaise were decent enough, and plopped himself down on one, spotting a woollen sweater draped over the back of the chaise. He pulled a sleeve closer and phased into it, sighing quietly as he made himself comfortable. "Oh boy, I hope they got cheese here," he said quietly.

As he stared up at the high roof, Plagg chuckled to himself as he thought about what could happen the next morning, meeting up back at either Nino's house or at the school with a most probably ticked off Adrien being one of those things.

But something completely different happened instead.

So how's that for a start? I know there's not really a lot that happens in this first chapter, but the plot will start to kick in next chapter.

I'll try to stick to a schedule for this (RIP me), but I really want to have this finished by Christmas! It is a Christmas fic, after all.

Thanks for reading, and until next time!
