Fairy tail Natsu x OC x Gray Juvia's sister?!

Umm, can we talk?

-kaori's pov-

As I was walking home I heard someone call out my name from behind me.

"Kaori!! Wait up!"

'That sounds like a girls voice, I wonder who it is?' I mentally ask.

"Kaori!!!" The voice yells again.

'Oh crap it's Juvia!!' I panic and start walking faster.

"KAORI!!! I said wait!!!!" She screams.

I stop dead in my tracks and sigh. My house is about a five minute walk from fairy hills. Either way you go to get home you have to practically walk past my house to get to fairy hills so it's inevitable that I will see juvia.

"S-sorry Juvia, what's up?" I ask turning around.
"GOSH, Juvia was calling your name for ages Kaori!! How didn't you hear Juvia sooner?!" She yells catching up to me.
"Anyway! Juvia is here to talk." She says firmly.
"What about?" I ask awkwardly trying not to stutter.
"Juvia wants to know if we are still friends?" She asks smiling.
"Of course we are" I say shyly.
"Juvia and Kaori are friends so Juvia wants to know why Kaori was hugging gray-sama today!" She blurts.
"Oh, I was carrying him home, Erza beat him up pretty bad" I reply smiling at her.
"Kaori is so sweet, why won't she tell anyone her last name?" Juvia blurts questioningly.
I freeze. Shit. This is bad.

"I don't have one" i say and smile as convincingly as I could.
Crap!!!
"Sure you do, everyone does, tell Juvia" she says with puppy dog eyes.
"I can't remember it" I say and start to turn around.
"You just said you didn't have one so now I know you do!! Tell juvia?" She asks sweetly, grabbing my hand.
"Juvia isn't letting go until you tell her. It's not that big of a deal" she says more sturnly but smiling.
"I don't know okay?" I say shocked that she's being so serious about this.
"Just tell juvia! I won't tell anyone if that's what you want?" She says looking into my eyes.
"No, Juvia I don't want to tell anybody. Not even you" I say and turn around.
"Kaori don't be cruel! Tell me!!! No one knows who you are. We are all just curious" She yells out to me.
"I'm sorry Juvia" i say and start running away.

Oh my gosh what have I done!
Suddenly Juvia is in front of me.

"Kaori tell me right now. I know something is up" she says sternly, no trace of a smile to be found on her face.
I pause.
"Juvia..." I start.
"I was born on the 11th of March 767, I am a pieces." I say looking down at the floor.
Juvia looks confused.
"That is Juvia's birthday..." Juvia says shocked.
"I had a twin sister who looked almost exactly like me" I say with a burning feeling in the back of my throat.
"I was taken at birth from my family. They took me to the middle of the forest and left me for dead. I only know my name because they left me a note" I say with tears staring to well up.
"A dragon named Tahlia took me in the moment she saw me alone. She taught me everything I know." I say as I try to push the tears back, still staring at the ground. I'm afraid if I look at Juvia she will be staring at me. I know she is, I can feel it.
"When I was 11 a man named Erigor found me walking alone in the forest, he told me if I didn't help him he would kill me. I ran as fast as I could but he still managed to hit me. I was so close to death that I passed out and went into some kind of mental trip. All I knew was that I had to find my sister again. When I woke up I was in hospital." I say starting to shake.
"When I got out of hospital all I did was search for my sister, day in and day out. I needed to find her, that's all I knew" I say terrified.
"Her name was Juvia" I say as a tear slips down my cheek.
I pause for a moment before looking up.
Juvia's face is full of mixed emotions. She looks scared and happy, confused and lost, almost angry, she's sad and excited but shocked completely.
"To answer your question, my name is Kaori Rose Lockser." I say as I start to cry.
"I finally found my sister" I say and turn on my heal, then start running as fast as I can. I have no idea where I'm going but I know I can't stop.
What have I done..... why did it have to be like this!?

-Juvia's pov-
I run to Kaori to see if she will talk to juvia. Nobody in the guild knows her last name and seeing as she asked to be Juvia's friend she might tell Juvia!
However Juvia was not nearly prepared for what she was about to hear.
"To answer your question, my name is Kaori Rose Lockser." I freeze completely lost.
Everything starts to click. We have the same features, we have the same looks and the same coloured eyes and hair. We are the same age, she wanted to be my friend from the first day she saw me.
"I finally found my sister" She turns and runs off crying and Juvia is left standing completely still.
"Kaori is Juvia's sister" Juvia repeats to herself.
"Why didn't Juvia know that she had a sister!!"
"KAORI!!!!" Juvia screams as loudly as she can however she doesn't seem to hear.

"Kaori........."
