-Kindergarten-

"Hey you!" A little girl said, coming to a stop at a table where another girl sat by herself. "How come you're not playing with anyone?"

The young girl that spoke felt a chill go down her spine and she stepped back a foot, a nervous sweat starting when scary blue eyes lifted to look at her from beneath blonde bangs. She let out a nervous smile.

"Hi, I'm Bella," The girl said, regaining her confidence and smiling. "What's your name?"

The other girl turned her head, deciding to ignore Bella. She put her small head on her hand to rest, looking out behind the fence and deciding to just ignore the girl.

That was, until this Bella, decided she didn't like being ignored and was suddenly sat next to her, a dopey grin in place looking at her. She let out a small scowl, hoping to scare the weird girl off, but it didn't work.

"You'd look a lot prettier if you smiled blondie." Bella said, blinking doe brown eyes at the face the blonde was giving her.

Light blonde eyebrows knitting together, the girl finally opened her mouth. "Who are you calling blondie? My name is Rosalie you dummy!"

Bella blinked, a smile forming on her face. "Ahhh, so that's your name! It's a nice name, but I think I'll call you blondie."

As little Rosalie opened her mouth to shout at Bella it came to a sudden halt when a hand was held in front of her.

"Let's be friends, okay?" Bella said, her head tilting sideways like a puppy.

Blue eyes scanned around the playground, before hesitantly, her hand reached out and held Bella's. "Okay, but stop calling me blondie."

And just like that, a friendship was formed.

-Elementary School, Grade 1-

"Blondie!" A 6 year old Bella shouted, her arm waving in the air, trying to catch her blonde friends attention.

Rolling her eyes, Rosalie bid farewell to her mother and twin as he left to go inside with friend Alice, catching up to Bella who said her byes to her dad and turned to face her with that silly grin.

"How many times do I have to tell you to stop calling me blondie dummy!" Rosalie shouted, puffing out her cheeks and crossing her arms.

"Hehe, come on, we're first graders now, stop pouting like a baby and let's go!" Bella laughed, holding out her hand for the blonde to take.

Blue eyes dropped from Bella's face to her outstretched hand before a hint of a smile settled on her face and she reached out to take the offered hand. "Okay."

"Hey Rosie," Bella whispered, coming to a stop at the doors into the school.

Rosalie's face took a small worried frown. "Yeah?"

"We're best friends right? Always? You won't leave me for a new friend, right?" The brunette said, her voice small.

Letting a rare smile take over her face, Rosalie squeezed Bella's hand tightly and stood as close as she could to her. "Always, I promise Bella."

From their first day at Kindergarten to their next step in Elementary school, the two friends were inseparable from each other. They spent time together at school, had play dates outside of school and sometimes their parents would take them out on the weekends to go to the parks or into the small town. As long as they were together, anything they did made them happy.

-Middle School, Grade 6-

"Bella,"

Humming and looking up from her desk, 11 year old Bella blinked and realised class was already over. She turned her head and saw her best friend. "Yeah blondie?" She said, grin on her face.

Clicking her tongue, Rosalie jutted her arm out and smacked the back of Bella's head lightly.

"Ow-Hey!" Bella cried out, squinting her eyes at the blonde and rubbing the back of her head. "What was that for?!"

Scoffing, Rosalie cocked her hip to the side and crossed her arms over her chest. "You know what it was for, knock off the blondie already!"

Bella growled lightly, staring at those blue eyes that she always enjoyed seeing, said blondes eyes levelling her with a glare in challenge.

"What's up though, Rosie?" Bella said, backing down and standing from her desk, hurriedly packing her stuff away.

Softening her stance, Rosalie took Bella's hand and interlocked their fingers. "Wanna come over to mine today? We can help each other with the homework and then get my mum to take us for ice cream?"

Bella thought about it, putting her rucksack onto her shoulder. "I'll have to ask my mum and dad, they've been a little on edge lately with me so my mum is watching me like a hawk for no reason." She said, her steps matching Rosalie's.

Blue eyes regarded her best friend, simply looking at the brunette. She had been slightly off the past few days.

"Bells," Rosalie said, coming to a stop in the empty hallway, turning Bella to face her. "What's going on, what aren't you telling me? We never hide things from each other!"

Blinking, Bella's face went somehow stoic. "It doesn't matter Rosie, let's go." She said, tugging Rosalie's hand.

Glaring at her friend and resisting Bella's pulling, Rosalie moved her hands to grab Bella's face and pinch her cheeks. "You liar! You're coming over to mine and we're gonna talk about this, I want my Bella back! Come on." The blonde finalised.

The two girls spent time at Rosalie's and it was no surprise that Rosalie dragged the truth out of her; Renee was freaking out about being in the small town and she and Charlie were arguing slightly and it was upsetting Bella which Rosalie didn't like. However, there was more to it; Bella was different to most girls, even boys, and Rosalie always suspected something, but seeing her best friend break down and cry about how she felt about herself broke her heart, and so she held the girl and promised her it would be okay and that she would never leave her.

-Middle School, Grade 8-

Bella wasn't sure how she was feeling about her best friend; things had changed for her and she hadn't started noticing until now. She had just turned 13, and her mum kept telling her all these things about puberty, she wasn't stupid, she knew her body was going through changes, but what didn't make sense was that things were changing when it came to Rosalie.

When she looked at Rosalie all she could see now instead of the little girl she'd become friends with was her turning into a beautiful girl; her blonde hair had grown out and always looked so soft and smelt nice and even the bangs she used to have had gone, her face was starting to lose the roundish appearance and thin out a bit, her nose becoming more accentuated and her lips always looked so plump and soft. Her body was changing, same as Bella's, only Rosalie was more femininely developing; rambling on about how she can wear bras now or that she'll have curves or whatever when she was older, she was even an inch taller than Bella herself now.

This was all fine, Bella was going through the same, but what didn't make sense was how when she looked at her best friend she couldn't help but smile or get a flutter in her chest, sometimes when they were with their friends hanging out she wanted to hold Rosalie's hand and tell everyone that she was hers only, or when it was just the two of them and she would take in Rosalie's presence and just gravitate towards her or want to hold her, sometimes when they hugged Bella wanted to kiss the girl too.

She didn't understand what this meant, and it didn't seem like Rosalie felt how she did either.

What started all of this off was that their group of friends had recently gotten bigger; Emmett Cullen had moved to town with his little brother Edward, and he was cute with his dimples and grin, and of course Rosalie was quick to invite him into the group. Bella got along with him more than she did the others besides Rosalie, but what she didn't like was that Rosalie and Emmett liked to spend time together, just the two of them. And she didn't like it.

"Hey Bella," Rosalie said, looking up from her homework from the head of Bella's bed, throwing her pencil at her friend to get her attention. "Earth to Bella, I've been calling you for 5 minutes!"

Bella jumped from her seat at her desk. "H-Huh?" She exclaimed, turning in her seat to look at Rosalie.

The blonde raised an eyebrow, staring at Bella. "You've been day dreaming for ages and ignoring me."

Blinking, Bella laughed and stood from her desk, walking to her bed and crawling up next to Rosalie to lay on her back. "Oh, sorry." She mumbled.

Dropping her work onto the floor, Rosalie turned on her side to face her friend, resting her head on her arm. "So, what were you thinking about?"

Bella's eyes moved sideways to take in her friend, before they stared at her ceiling. "I was thinking about how you're gonna leave me for Emmett." She said, blunt as could be.

She didn't dare look at the blonde, knowing her bluntness may have upset her or made her angry, she was expecting a lash out, but what she didn't expect was the blonde to move so fast she barely saw it, and before she knew it Rosalie was straddling her waist, pinning her arms with her own so Bella couldn't move.

"Hey! What are you doing, get off!" Bella shouted, kicking her legs out to try kick her friend off. She wouldn't admit it but it felt good having the blonde sitting on her.

"No!" Rosalie said, squeezing her legs harder to get Bella to stop moving. "Why would you say something like that? I'm not gonna replace you Bella, it's just you and me."

"I'm not stupid! I see the way you look at each other and Alice said that you two would be each others first kiss and that means you're gonna leave me!" Bella carried on, stopping her kicking about but she could feel her eyes welling up with tears.

"I'm gonna kill Alice..." She muttered and Rosalie sucked in a deep breath. "Emmett won't be my firsts, I want it to be you Bella." She said.

Bella's eyes quickly opened and she looked at her friend; Rosalie's cheeks were red from blushing and she looked nervous and shy after saying what she did. "You want me to be your first kiss...?"

Not saying anything or looking at Bella, Rosalie nodded her head and twiddled with her fingers.

Pulling herself to a sitting position, Bella gulped. She'd never kissed anyone before, but if Rosalie wanted her to kiss her then she would try do her best!

Bella's hands came up to cup Rosalie's cheeks, getting the girl to look at her. She rested their foreheads together. "C-Can I have your first kiss Rosalie?" She stuttered, feeling her face blushing beet red.

Once again Rosalie didn't say anything, but she slowly nodded her head and closed her eyes, letting Bella make the move. Hearts thumping in their chests, Bella gulped and nervously inched forwards, Rosalie's lips so close to her own. Her eyes started to close when she knew she'd get Rosalie's lips fine without them, and she didn't hesitate the rest of the way.

Their lips met together, a peck lasting a few seconds before Bella pulled back and wrapped her arms around Rosalie, who in turn buried her face onto Bella's neck.

"I told you I'm not replacing you and now you can't ever leave me! You're mine now." Rosalie said, her voice muffled.

Bella grinned. "I won't blondie, promise!"

-Summer before Middle School, Grade 9-

"What do you mean you're leaving Bella?!"

Cowering slightly, Bella looked down at her shoes, unable to meet Rosalie's heartbroken eyes. "I'm not going forever, I'll be back in a few years Rosie!" She said.

Rosalie's chest heaved, she stood from Bella's bed and quickly grabbed her bag. "You promised me you wouldn't ever leave me Bella! You can't just say you're moving to Arizona and expect me to be okay with it!"

Bella moved, grabbing Rosalie's hand to stop the girl from leaving. "I'm sorry! You know my mum and dad are getting a divorce, my mum is making me go with her and I begged my dad to let me stay with him but you know what my mum is like! It won't be for long, I swear I'll do anything to stay here with you!" Bella cried, feeling Rosalie trying to pull her hand away.

"You're still leaving Bella! You may as well be moving half way around the world!" Rosalie shouted, feeling tears of her own starting to well up.

Bella sobbed. "Tell me what to do to make this better, I'll do anything, promise!"

Rosalie snarled, pulling her hand away and turned to leave, but Bella quickly grabbed her into a hug and they fell to the floor, sobbing and crying.

Bella laid on top of Rosalie, holding the girl tightly while Rosalie kicked and hit her back with weak fists to get her off. After a few minutes Rosalie stopped moving.

"I don't want you to leave, don't leave me..." Rosalie sobbed, finally giving in and holding onto Bella like her life depended on it.

Bella held Rosalie tight, her own tears falling. "I'm coming back for you Rosalie, I swear it I'm coming back to you! Just wait for me, tell me you will?"

Rosalie nodded her head, bunching the back of Bella's top. "I will, I'll wait for you."

It had to have been the hardest thing Bella ever did, turning and walking away from Rosalie to board her plane, hearing the blonde call out her name or beg her to come back, but her mum was dragging her onto the plane and she wasn't strong enough to stop her. Once that plane set off she knew she wouldn't see Rosalie for a while, but the blonde said she would wait for her, and she seriously hoped she would.
