Hey guys, so I wanted to write a CS AU that involves some of my favourite types of CS stories such as childhood best friends!

I hope you enjoy it cause I'm certainly having fun writing it.

DISCLAIMER: I do not own or claim to own any characters or names from Once Upon A Time, that belongs entirely to the wonderful writers Adam Horowitz and Eddy Kitsis.

LOST AND FOUND

PROLOGUE - Meeting You :

Aged 11:

Emma Swan wasn't considered as popular. She wasn't unpopular, but she was not popular. At least, not worth other girls. Emma Swan preferred boys; always had, always would.

So when the new kid joined her home room, she vowed to be his friend. The other kid was a girl, and Emma was not about to let down some of her walls to someone called Regina Mills.

But, somehow, she was prepared to let Killian Jones into her blocked-off life.

From the moment she met him, she knew she was hooked. She couldn't explain it, he was thin and scrawny, his hair was far too messy and he wore an overly baggy t-shirt.

Yet something about the way that when he smiled his ocean blue eyes sparkled.

Killian Jones was an enigma that Emma was determined to crack.

Her home room tutor, Mr Gold, introduced Killian and Regina to the class, causing them to look incredibly uncomfortable and nervous.

Regina was placed next to Emma's best friend, August Booth, and Killian was placed next to Emma. She immediately stuck out her hand to him.

"I'm Emma. Emma Swan." She announced boldly. "I'm gonna make sure you settle in here." Killian laughed and shook her extended hand.

She couldn't help but notice that it was warm.

"Thank you." Emma's eyes widened in shock.

"You're British?" She exclaimed. "Why did you move to Storybrooke of all places?"

Killian chuckled again and Emma's heart leapt.

"My dad owns a vessel, and we set sail a few months ago before docking at the first port we came across. We found the town quaint and comfortable so decided to settle."

Emma blinked, speechless.

Killian smiled widely and scratched the back of his neck. The bell rang.

"Come on, Killian." Emma took his hand again.

"I'll show you to your first lesson. What have you got?" Killian checked his timetable.

"Math with, erm... Hold on..." He squinted at the name on the paper. Emma chuckled and looked over his shoulder.

"Dr Hopper, that's awesome." Killian looked at her, a quizzical glint in his eyes. He raised an eyebrow.

"May I ask why?" Emma smiled brightly and Killian felt his stomach drop.

"You've got the same class as me. Come on, Killian." She pulled on his hand.

At eleven years old, Killian Jones never would have imagined that he could fall in love so fast and so irreversibly.

But Emma Swan's decision to become his best friend allowed him to do just that.

Sorry this is short but the next chapter will be up as soon as I'm done with it.
