A/N: Hey guys! This is the first chapter, told in Mari's POV. This part is a little explanation, about what's happening, but I'm not going into her backstory just yet. Please comment and as I said before, it'd be appreciated if y'all point out any grammar mistakes. I will definitely be editing these parts later, but for now, enjoy!

Lila Rossi. The lying snake. The devil in disguise.

Oh I'm sorry. I forgot to introduce myself!

Hi, my name is Marinette Dupain-Cheng or just "Mari" for short. I live in Paris and I am currently 17 years old and in my last year of high school. I want to study fashion designing, which is my hobby. Speaking of which, I am also the famous fashion designer MDC, which stands for my full name. I am also the famous heroine Lady Noire. I wear both the ladybug and black cat miraculous. The miraculous are basically magic objects in the form of jewelry that grant powers meant to serve the greater good. I received the miraculous when I was thirteen and became the guardian of the miraculous when I was fifteen. There was a villain called Hawkmoth, or Shadow Moth. He was in possession of the butterfly and peacock miraculous. He would use peoples' emotions against them and send out akumas (Small butterflies made out of corrupted energy) and turn them into villains, also called akumatization. I would then have to fight that person and de-akumatize them which means expelling the akuma from the object it merged with, then purifying it. I also have a bunch of partners, who not so coincidentally happen to be my civilian best friends. They are: Honey Bee (Chloe Bourgeois), Viper (Luka Couffaine) and Tatsu (Kagami Tsurugi). I used to have a partner who wore the black cat miraculous, Chat Noir (Adrien Agreste), but he abused it and his kwami, Plagg. He also stopped showing up to battles, except when flirting or asking me (Ladybug) out, and when I'd reject him, he'd snap and hop away, going to my house to ask out my alter ego (Marinette). When he'd find no one there for a very obvious reason, he'd go back to wherever he came from and not show up for weeks, only to repeat the action over and over. Eventually, Plagg flew into my room and asked me to take back the miraculous, claiming his holder was not a good fit. I did so, and started wearing both miraculous.

After four years of battling a guy who can't get over the death of his wife, we defeated him. He turned out to be Gabriel Agreste, with Nathalie as Mayura, and honestly, I wasn't even surprised. If his son was a terrible person, why can't old mean Gabe be one too? Anyways, he and his assistant Nathalie each received a life sentence in jail.

Anyways. Back to what I was saying. Lila Rossi. The girl that caused my life to shatter into a thousand pieces.

See, I used to be really popular in my school. I had a lot of friends and everyone loved me.

However, when I was fourteen, a new girl joined our school. Her name is Lila Rossi. To me? Lie-la Rossi. Why, you might ask? She's a pathological liar. Literally. She lies with every breath, about anything or anyone. When I outed her in front of our class, she threatened to take away my life if I didn't join her. I didn't, and she stayed true to her word, taking everything precious from me, except for my best friends, Chloe, Luka and Kagami.

It's a little ironic how I'm friends with my former enemy, Chloe. We used to hate each other like our life depended on it and now, we're very close, telling each other our deepest, darkest secrets.

Actually, I had a stupid crush on Agreste, the former hero. I was obsessed with him, but when he told me to take the high road and be quiet about Lila's lies, (Yes, he knew about it) My feelings began to slip away. When I saw him kissing the liar, all the feelings disappeared. (Keep in mind this was before I knew Chat Noir was Adrien)

After that… pathetic excuse of a crush, I decided to focus on myself a little more. Gone were the childish pigtails, in its place were buns. Neat buns, messy buns, plaited buns, you name it. I also got rid of the color pink. I repainted my bedroom walls to a light gray and decorated the walls with fairy lights, photos of my friends and I, and mannequins.

Finally, I changed my style and my entire personality. I wasn't the sweet and kind Marinette Dupain-Cheng who'd give away the clothes she had on her back even if they were her last ones. No. I am the calm yet fierce Mari. I wore sporty clothes, and a whole lot more leather. I changed the way I spoke, how I interacted with my friends and my enemies.

All because of Lila Rossi.

Alright! One chapter done! Once again, please point out mistakes and comment!
