Hello, this is Sapphire checking in! This is my first time writing in the Miraculous fandom, as well as my first time writing a multichapter fic. Please keep this in mind when you read this- I love and appreciate constructive criticism, but please don't be jerks. Trigger warnings: Adrien's father will be physically abusive, and he will be hurt badly later in this story. There is an OC who has had abusive foster parents, and things that have been done to her will be described. There will be graphic violence later in the story. I'll tag a warning on those chapters when the time comes. Thanks for reading!

Chapter 1: Celine

oooOOOOooo

"Did you hear, Mari? There's a new girl coming to our school! I wonder what she'll be like. What do you think?" Alya called out to her best friend, running up to meet her.

"I just hope she isn't like Chloe! Or Lila!" Marinette exclaimed as the pair walked up to their school, Francoise Dupont.

As the two girls climbed the stairs, they saw their principal and Miss Bustier walking a girl with long, blonde hair into the school. They could only see the back of her at first, but she turned to talk to Mr. Damocles. She had brilliant green eyes and looked almost identical to Adrien Agreste.

"Woah! I never knew Adrien had a twin!" Alya exclaimed. "She looks almost identical to him!"

"I wonder if Adrien knows about her," Marinette wondered. "What if she's adopted?"

"We'll find out when class starts. Come on, girl!" Alya grabbed Marinette's hand and dragged her the rest of the way to their classroom. They sat in their usual seats and chatted for the remainder of waiting for class to start as their other classmates filtered in.

OooOOOOooo

"Good morning, class! Today, we have a new student! Her name is Celine Leblanc, and she will be joining our class. Please be welcoming. She has had a difficult past and doesn't need to share anything with you if she doesn't want to. She'll be here in a minute or two," Miss Bustier announced to the class.

Kim's hand shot up. "Yes, Kim?" Miss Bustier called. "Can we ask her questions?" he asked.

"Be careful and sensitive. I'd suggest letting her decide what to tell you and when. But if you're careful, you can ask questions," Miss Bustier replied.

Just then, Mr. Damocles walked in with the blonde girl Marinette and Alya had spotted earlier. Several of their classmates did double takes.

Celine walked to the central front of the room to introduce herself. "Hello! My name is Celine Leblanc, and I'm so happy to be in school again! It's been a while since I've been able to be with people my own age. My last foster parents weren't very kind, and they didn't let me go to school." She then turned to Miss Bustier. "Where should I sit?"

"Why don't you sit in the back next to Lila? Lila, raise your hand so she knows where to sit," Miss Bustier instructed.

As Celine moved to her new seat, she stopped at Adrien's desk. "You're that model that looks almost exactly like me! Adrien, right? Are you adopted, too?" she asked him.

"Um, no," he replied.

"Hm," she sounded as she went the rest of the way to her new spot.

Miss Bustier started class, but no one was listening. They were all too curious about this new girl, Celine. Adrien was especially curious about her. He wondered what her past was like and had an idea that her childhood was like his own- abused by the people who were supposed to be the ones who loved them.

oooOOOOooo

When lunch came that day, Celine was bombarded by questions about her past. Rose tried to cut in, saying, "Miss Bustier told us that she doesn't have to share her past!"

"No, it's fine. I'd rather just say everything that's happened to me than have rumors spread," Celine said. "A lot is in the distant past, and I don't mind people knowing my past. I prefer to be an open book.

"I'll start from the beginning. When I was a baby, I was kidnapped from my birth parents. I have never figured out who they were. The kidnappers had me until I was 4, when I was rescued by the police. I don't remember much of what happened, but I do know that they were very abusive. After that, I was placed with a kind foster family. Unfortunately, they were killed in an accident when I was 8, and my next foster family was also very abusive.

"From the time I was 8 until I was 10, I was with a family that hated children and only got me because of pressure from others. They beat me many times. I didn't know that it was a bad thing, so I never told anyone, and when I did, the social workers were furious! The next home was not horrible, but not great, either. I was neglected there. That family is the reason I know how to cook. They didn't let me go to school, so I had to teach a lot of what I know to myself. When I was 13, I got fed up with it and ran away. I now live with an amazing family who loves me. I've been there since May. They wanted to homeschool me for the entirety of this year, but I convinced them to let me join this school after a couple months. So here I am!"

"What's your current family like?" Max asked.

"My parents are a couple who couldn't conceive, so they decided to adopt several children. I am the only 14-year-old, but I have both a brother and a sister who are 17. I also have 6 younger siblings, 10 and under," Celine told them.

"That's so cool! I wish I had that many siblings!" Marinette exclaimed. "I'm an only child, so I don't know what it's like."

"You have 6 younger siblings!? I only have 2 and they drive me crazy! I can't imagine!" Alya exclaimed.

Celine laughed. "They drive me crazy sometimes, but I love them. They love me, too!"

The rest of the lunch was spent talking about the hilarious things younger siblings do sometimes, and there were many laughs and smiles throughout the rest of the day.

oooOOOOooo

When Adrien got home, he prayed that his father would be working. He still felt the bruises on his ribs where he had been beaten last.

OooOOOOooo

So, what do you think so far? Please read and review! I have several ideas of where to take this, but if you have any, please share!
