A/N: This idea was inspired by another work I saw here on FFN. As soon as I see/remember that work, I'll credit it.

Also, this is a secondary work of mine. Posts will be sporadic, as I'm concentrating on my first story "Confessions of a Teenage Superhero". I promise it will have a conclusion, as reading half-finished stories with no possibility of an update is a HUGE pet peeve of mine.

Chapter 1

Six beings (four teenagers and two Kwamis) stared at the same photo and wondered What happened that caused Ladybug and Chat Noir to have such a passionate kiss at the top of Montparnasse Tower before the Miraculous Cure restored everything?

Marinette stared at her computer and wondered how she could possibly have kissed her partner like that when her heart irrevocably belonged to Adrien. She didn't want to hurt her partner's feelings.

Adrien figured that if he could get Ladybug to fall in love with him when they'd lost their memories that he could do it again but lamented the fact that he didn't remember the kiss. He looked at the photo on his computer about once a month (week? day?) to dream about that possibility.

Alya and Nino were hanging out in Alya's room. Alya was remembering how excited she was to take the photo in the first place because it seemed that LadyNoir was finally going to be canon. She figured that whatever the reason for Ladybug to reject Chat Noir's advances, there was obviously something there and wondered if a kiss like that would happen again.

Nino was supporting his girlfriend as she spoke about the LadyNoir 'ship and thought the photo looked cute. He wondered what had happened while Ladybug and Chat Noir's memories were gone which would lead to such an intense PDA.

Both Tikki and Plagg figured that at some point the two superheroes had to have detransformed, and knew who both holders were. While it was disconcerting having no memory, especially as a magical being, the two Kwami knew that Ladybug and Chat Noir were meant to be close as that was the yin-yang nature of the two miraculous.

Considering how Marinette was head-over-heels for Adrien, Tikki knew that would have been a factor leading up to the kiss and wondered if they were able to see both sides of each other.

Plagg was just tired of Adrien staring at the photo, whining about his love life, and teased him mercilessly. He wondered how he could help his holder be less oblivious. Or if that was even possible.

Little did the six beings know that by pondering questions while staring at the same photo at the same time, they created a link that would reveal the lost memories. But with magic, as in life, there are always surprises.

The first incident happened while the four friends were playing video games at Alya's. It was one of those super-rare occasions where Adrien was there in person, having permission to attend the "study session". (They actually did study first.)

Alya and Nino were playing their favorite dancing game while Marinette and Adrien waited for their turn. This particular dance move had the two players practically in each other's arms. Suddenly, they paused, losing their place in the game.

"Do you think we'll remember all this afterwards?" Nino remembered asking as his black-gloved hand touched the spotted heroine's arm.

"Apparently, my Miraculous Ladybug reverts everything. So I'm guessing we won't," Alya remembered replying.

"All right, then. With your permission, Milady," Nino said as he took the spotted heroine in his arms and looked deep into her gorgeous bluebell eyes.

Alya looked at the face of her partner and found herself closing her eyes and leaning in. The kiss was gentle, sweet, and carried the promise of much more to come. They broke apart reluctantly, and Alya knew what she had to do. "Miraculous Ladybug!" she cried, throwing the ladybug-patterned teapot into the air.

Nino and Alya came to themselves and found they were staring at each other while holding hands, ignoring the game completely. For a moment, they didn't know where they were, confusing the intruding memory with reality.

"Giving up on the game," Adrien teased with a smirk.

"I know you guys are dating, but are you really going to give up the round so easily? Or would you rather go snog in a corner?" Marinette couldn't help but razz her friends.

"That was… " Nino was at a loss for words.

"... weird," said Alya as she shook her head, looking first at her hands and then at her boyfriend's face.

Marinette was concerned by their response. "Ok, guys. What happened?"

"This is going to sound so strange," said Alya, coming over to the couch to sit by her bestie. "I just remembered something, but it wasn't my memory."

"Me too, dudette," piped in Nino.

"What did you remember, Nino," Adrien asked his best bud.

"I remember asking Ladybug for permission to kiss her," he said a little shyly.

"What?" Marinette was shocked. Adrien looked a little pale himself.

"I've never asked Ladybug for a kiss. Ever." He seemed a little distressed as he looked toward Alya. "I think it was Chat Noir's memory."

"That's okay because I think I just remembered Ladybug's memory of the same incident." She looked at her boyfriend. "Chat Noir had asked if the Miraculous Ladybug cure would bring our memories back. I said that I thought so, and then he asked for permission to kiss me. I looked at him, closed my eyes, and felt a rush of passion as we kissed. Then we broke apart, and I threw the Lucky Charm into the air to reset everything. The next thing I knew, I was back here, holding hands with Nino and the round was over."

"Yeah. That's exactly what I remember her saying," a confused Nino said.

"Do.. um, do you rem-remember where you were at the time? In the memory, I m-mean," Marinette stuttered.

Both Alya and Nino thought for a moment. "I'm not 100% sure, but it looked like a rooftop," said Nino.

"I bet it was the top of Montparnasse Tower!" Alya was excited. "You know, that kiss I snapped a photo of after we were freed from being Oblivio? I think I was living that!"

"You know what, babe, I think you're right."

Marinette seemed a little embarrassed. "I still wonder what could have possessed Ladybug to do that when she's been so adamant that Chat Noir is not a romantic interest."

"Who knows," Adrien said with a sigh. If one didn't know better, they'd say he looked wistful. "But whatever it was, I bet Chat Noir hopes it will happen again someday."

"But how could you remember something that you weren't part of?" The higher-pitched voice showed Marinette's stress level.

"Well, we were part of it," said Alya. "Sort of. I mean we had just been freed from being Oblivio."

In Adrien's pocket and Marinette's purse, two powerful, magical beings silently considered the ramifications of what they'd just heard.

The next incident occurred that same night as Marinette and Adrien were on their way home. They needed to leave at the same time, so it was just the two of them (and their Kwamis). The elevator was a bit older and lurched slightly as the doors closed, causing Adrien to stumble in the far corner and Marinette against the wall.

Marinette looked at herself. She was dressed in what looked like black leather. Then she looked over at the girl in the elevator. She was dressed in what looked like a red jumpsuit with black spots, and a similarly themed domino mask on her face.

"Looks like you and I were at the same costume party!" she said.

Adrien looked at himself and the boy in the corner. He noticed the boy's ring. Pointing at it, he asked, "Why is that flashing?"

Marinette looked at her ring, then at the girl's jewelry. "And your earrings, too! We must shop at the same jewelry store!"

Adrien was confused. "Are we supposed to know each other?"

Marinette was just as confused. "I'd be surprised if we weren't."

The beeping from the ring and earrings got faster. Suddenly the lipstick near Adrien disappeared, as did the costumes. Even stranger, two creatures flew out of the jewelry. Adrien was scared and scooted over to the boy in the corner.

"Aaah! There are giant bugs! Mice? Bug-mice!"

Tikki lifted up her black head. "Wow, I am starving right now!"

Marinette thought the creatures were cool and slid over to the one that came out of her ring. "Hi, there! What are you, exactly? Genies, like the one in the lamp?"

"If I'm a genie," replied Tikki, "where is my lamp? Besides, where am I? And who are you!"

Adrien slid behind the boy again, seeking comfort. He pointed at the red bug-mouse creature. "What's that thing doing in my earring?" he asked.

"I'm not a thing," Plagg replied indignantly in his high pitched voice. "I'm …" He gasped. "I don't know what I am!" His stomach gave an embarrassing rumble. "But I do know I'm very hungry."

At this, Adrien's natural sympathy kicked in, and he picked up the red creature. "Aw, poor little … no thing," he said as he ticked the creature's tummy. Plagg giggled.

The two teens stumbled a little.

"Whoa! What was that?"

"The elevator lurched," said Marinette. "And then…"

Adrien looked over at his friend. "Did you see something?"

"Yeah. I was trapped in an elevator with no memory. I looked over and saw m… Ladybug."

"Same here. But I saw Chat Noir in the corner." Adrien seemed really confused. If he was looking at himself in the corner, then did that mean he had Ladybug's memory? It must because he remembered picking up Tikki. And looking at himself pick up Plagg.

What in the hell is going on? both teens thought simultaneously.

When she got home, Marinette rushed straight to her bedroom to have a heart-to-heart with her Kwami.

"Tikki, tonight was definitely weird! Did you hear what Alya and Nino said? And then in the elevator on the way home… I think I was remembering Chat Noir's memory."

"It happened to me, too, though I was Plagg in the memory."

"Any idea why it's happening?"

"Maybe, though I'm not sure. I'll need to talk with Plagg about it."

As soon as Adrien was left alone in his room, Plagg raided the stash of Camembert (as per usual).

"Plagg, do you know why Nino and Alya would be remembering Ladybug's and my memories? Also, why would I remember something that happened to Ladybug?"

"I'm not sure, exactly. But it's happening to me, too. I remember Ladybug tickling my tummy, and I sounded like Sugarcube. And I remember craving sweets. Blech!" He downed a piece of his precious cheese. "Let me think about it a bit. I'll also need to speak with Sugarcube."

A/N: This is the official first chapter. The first one I posted was more of a placeholder.
