A/N: Yeah...I wasn't away for very long was I? I got writers block for my childrens novel, and I still needed my word cound for National Novel Writers Month...so I wrote this up. This is based on an old one-shot I wrote called Cats out of the Bag. Which didn't work out the way I wanted it too. I wanted it to be funnier. And while this chapter will probably come across as a little heavy, the next chapters will be funny. I promise.

Please Keep My Secret

Chapter 1

Marinette didn't mean to witness him untransform that day, and if she realized she would have seen him she would have gone in the opposite direction. Of course, she had all the rotten luck in the whole, she just had to run into him that day! Ladybug and Chat Noir separated after an Akuma battle during a school trip to the Musee De L'Orangerie that had been the driving force behind what happened.

A custodian falsely accused of a crime, and after battle filled with dirty mop water, Marinette ran for a place to untransform without being spotted and found one alleyway where she changed back but during the search for her classmates who fled in the attack that caused so much issue. When Marinette cut through the alleyway to get back to the courtyard, where the school tour was attacked; when she froze in her tracks by who she saw trying to hide by the dumpster.

Her eyes widened and her mouth hung open as she stared at Chat Noir, standing there. He noticed her and their eyes met. His mirrored the panic in hers, and he turned to run. The moment she looked at him, she realized this was the moment he would untransform. She wanted to turn her back to him so she couldn't discover his identity, something she positively didn't need to see, but there a swirl of black and green around his body, and it left a blonde boy standing in the middle of the alleyway in front of her, his eyes wide and he still stared at her. Floating beside him, a tiny black cat-like creature, who looked like a Kwami.

"A-Adrien?" she gasped.

His stunned expressed also echoed hers and he stared at her like Marinette was a monster from one of his games. No one would deny what she had just witnessed. Adrien Agreste had just untransformed from Chat Noir. Adrien Agreste was Chat Noir.

He shifted, and she knew he was trying to search for his words because she was trying to search for words. Her mouth was open, but words weren't forming and nothing was coming out. She felt like a fish with her mouth opening and closing, but still, no sound was coming out.

"Marinette! Adrien!" Their attention drew away when they heard Alya's voice from across the other side of the alley. Both turned, and the Kwami disappeared inside Adrien's jacket.

Alya ran down the alleyway and met them. "I'm glad you guys are okay! Did you get hit with that thing's dirty bucket water? My backpack completely soaked!"

"N-n-no!" Marinette stumbled. "Not me. I avoided his attacks."

Alya looked Adrien up and down. "Looks like you managed to avoid it too. Lucky, everyone else got soaked."

Adrien looked back at Marinette and her cheeks flushed. She had only a second to process anymore because Alya met Marinette and put her arm around her. "Catching some alone time with Adrien are you?"

"N-n-n-nooo," Marinette repeated. " We were both just heading back to the courtyard and met up. That's all."

Adrien looked like he would be sick, and she imagined Adrien felt terrified that she would tell Alya Chat Noir's identity. If she ever found out, it would be on the internet in seconds. Marinette would never do that to her partner. Marinette didn't even want to know his identity because she didn't want him to know Ladybugs true self. There wouldn't be any relief knowing Chat Noir, her flirty partner, is Adrien. That wasn't the guy she saw at school every day, and that wasn't the boy she was madly in love with.

Alya was rushing her into the courtyard where she saw her classmates and some other folks gathering after the Akuma attack. Marinette sensed Adrian close behind, but she could not bring herself to even look back at him. Alya took a seat on a bench and Marinette took a seat next to her. She placed a hand on her bag and Tikki moved around a little inside. Her heart rate quickened, and it got worse when Adrien passed by and didn't even glance at her. Then she let it sink into her chest. She wanted to throw up. She looked at Alya who was chatting away about the footage she had from the battle earlier and how she would present it to her blog tonight. Marinette couldn't speak though. She held back a sigh and pretended that she was listening to her friend.

The class was dismissed and Marinette went home. She collapsed onto her bed before she drew herself into a fetal position, holding her limbs close to her, protecting herself from an invisible pain. Though it still peaked through into her chest. A pain in her chest as it tightened up. She opened her eyes and looked at Tikki who had freed herself from Marinette's purse and was sitting on the bed by Marinette's face.

"Marinette? Are you all right?" the tiny Kwami asked. "I thought you would be happy to find out that Adrien was Chat Noir."

"I don't know Tikki," she explained. "I thought I would be too, but it doesn't feel right. Chat Noir and Adrien are...so different. Adrien is a little goofy at school, but he's very serious. Chat Noir doesn't take things nearly as seriously as he should and would flirt and make jokes all day."

Tikki giggled. "Flirttttt? Marinette, that means Adrien's been flirting with you!"

Marinette shook her head. "No, that means he's been flirting with Ladybug, not me. That's exactly why I didn't want to reveal myself to Chat Noir or him to me." She covered her face, and she shook it in frustration. "Ladybug is so different from who I am. Adrien looked terrified and he avoided me the rest of the day. He couldn't even look at me! Because it's me! He doesn't like Marinette! He likes... her!"

"Marinette, you're overreacting," Tikki stated. "If I remember correctly, Chat Noir flirted with you too, as yourself Marinette."

Marinette remembered, and how she mocked him teasingly behind his back that day. He gave her the nickname Princess, and he bragged about how he would save the day. She heard every word that would come out of his mouth before he said it. It was only because she had familiarized herself with Chat Noir. They had been fighting beside each other for so long. She guessed she didn't know him as well as she originally thought, after all that last person she would have suspected of being her partner was, Adrien Agreste.

Her eyes stopped on the pull-down chart she made that tracked Adrien's schedule and the pain in her chest worsened because she realized she had been wrong about Adrien. Marinette thought she knew everything about him because of her obsessive crush. She covered her face with her hands she realized it wasn't true, and she didn't know anything about him at all.

Adrien was in a panic and had he had been the moment his classmate, Marinette had seen him. He wanted to run away, but that wouldn't fix this problem. So when he got home and went to his bedroom he felt the full weight of his situation fall over him. Plagg flew from Adrien's jacket and was already looking for his afternoon snack. Plagg didn't seem the least bit concerned.

"Aren't you worried?" Adrien asked. "Even just a little."

Plagg shrugged his shoulders. "It's not the first time it's happened. It was bound to happen sooner than later."

"But what if Marinette tells everyone?" Adrien stated. "I need to know she won't tell anyone, especially Alya. If she finds out, I'm sunk."

Plagg found his cheese and munched on it and still didn't seem the least bit worried. Adrien felt awful and like he should crawl into a hole. He turned to his computer and jumped on and searched through his usual browser tabs. There was the Ladyblog. He refreshed it twice and presently the only new post was that of Ladybug fighting the Akuma from earlier, and he breathed a sigh of relief.

Adrien clicked on his social media and gave a quick search of his classmates. Only talk of the school trip and the Akuma. He sighed when he searched for Marinette and saw no new updates. She uploaded some photos of a spring dress she was working on and the posts were over a week old.

He was so worried that she would reveal him, and so he knew he had to take action before it was too late. He clicked on the private message button and typed out a message to send her.

Marinette, We really need to talk about what happened earlier today. I'll be on your balcony on your roof at 9pm, just after it gets dark. Please tell no one.

He sent the message and now stared at the screen waiting for her reply. The three dots showed up showing that she was typing a reply, but she took another few minutes to sent back a reply.

All right, I'll see you then.

He felt only some relief when he read the message from her. He still had to talk to her, which would be the real challenge. She was such a quiet girl, and she didn't seem to like him that much. She was talkative to everyone except him. He shook his had as he covered half his face with his hand. He prayed this evening would just be over with already.
