Hi! It's my first time making a ML fic! English isn't my first language so, it may (it sure have) have a few errors. I wanted to do this chapter longer but it ended this way. I hope you guys like it!

Chapter 1

"What the hell..." Adrien said looking at the things in front and around him. Everything was bigger or he was the one who had shrunk? He looked down and his eyes at what seemed to be his hands he saw black flurry, his bell was still there, but now he has also a real tail. "I'm a real cat?! Plagg!" He yelled, but all he heard was a 'meow'. Dispair took place all over his face, with his pawns on his face he got really worried. Desperately he started to look around, searching for his little kwami, and got surprised that now he wasn't that small. "Plagg, wake up!" the little kwami was lying on the floor, he was breathing but unconscious. Decided he grabbed Plagg with his mouth, carefully to not hurt him and not puke. He looked around and found a safe place near the park. It took some time to Plagg wake up, but once he did he laughed at Adrien.

"Chat noir is a black cat!" Adrien frowned mad at him, but it let him cuter.

"Mind to explain? Why the hell I've turned into a cat?!" Plagg smiled evilly.

"Chat noir is a cat too~~" Adrien's pawn made it way to the kwami, and now he was under it, the ground under him. "Ok ok, I'll stop." Grinning with his victory Adrien let him go. "Well, this can be, kinda of, a side effect of being Chat Noir."

"How so?" He titled his head trying to understand.

"Well, you're not the first chat to turn into this. When you stood in Chat Noir form for too long or keep transforming it can happen." Adrien's frown grew. He really was being Chat longer these days, a lot of akumas keept poping up and he had to keep transforming.

"I see... how long it'll take to me to come back to normal?" Plagg smiled and scratched the back of his head.

"Well... it depends. It can be hours or days."

"What?! You're kidding right?!" Plagg shocked his head and Adrien got really worried. "Oh my god... what I am going to do?! I don't have school to worry about since its Friday but, I have photoshoots!" The kwami sat down on his head and sighed.

"First you have to tell Ladybug that you can't help her. Since she's the only one who can understand you besides me. Maybe she can also help you with your issues?" Adrien frowned deeper.

"I can tell her that I have a problem and can't help her for a while but about my identity... I don't think she'll want to know about it." Plagg shrugged.

"If you say so." Then he flew in front of the cat. "Call her." It took a while but she got the call.

"Where are you Chat? I need you here!"

"Huh about that... I was on my way when something happened to Plagg... He can't transform me for a while." The kwami made a mad face to him, he had to blame him?

"That's bad. But you guys are ok?" He smiled at her concern.

"Yeah, but I'm really sorry for not being able to help you." He could feel her smile coming to her face.

"That's ok kitty, just take care and come back as fast as possible." Then they hang out. Now that this problem was solved he had to fix his private life.

"Plagg hold on. We are going to my house." The duo crossed Paris in what seemed an eternity. As he was little, and not Chat, it worned him out. By the time they got home it was already late at night and he managed to sneak in into his room and lay down on his bed. He had to think about his problems but he was so tired with the distance he ran that the little cat falls asleep before noticing it. When he opened his eyes the sun was already rising, it took a few seconds for the dispair come back to him as he noticed that he were still a cat and it was almost time for Natalie to enter his room to wake him up. He hurried to his computer and was glad that he had some voice files on it in case of an emergency. He found the one he nedded and called Natalie and as soon as he heard her voice he tensed.

"It's good that you're awake earlier. Need something?" Adrien took a deep breath before pressing the play.

"I'm sick. I think I can't do anything this weekend." He was really glad that he remembered these files in such a hurry.

"I'll go there to see how you are." Then he panicked, but managed to find another file fast enough.

"Don't worry! What if you get my sickness? My father can get mad at you..." It made her think for a while.

"Ok. Do you need something?" He sighed in relief.

"No, I can manage it. Thanks."

"Ok. I'll change your schedule, take a rest." Then she hangs out.

"Plagg." The kwami got up from his spot on Adrien's bed.

"Yeah?"

"When I turn back to normal, I'll be Adrien or Chat?" The kwami smiled.

"Since you turned into a cat when you were chat, you'll turn into him. But I need to be near you all the time, or else you'll turn into yourself." Adrien jumped off the chair and landed on the ground and went walking near Plagg.

"I wanna know how a street cat lives, wanna come?" Plagg's face got brighter.

"Of course! Let's go!"
