Sorta Kinda like The Notebook but, my version with Destiel :)

Prologue

It was a dark yet calm night, as Castiel sat by the window of his room, staring out at the raindrops as they slowly slid down the window and disappeared.
His eyes were dull and expressionless, as he saw his reflection in the window's clear wet glass.
Hair a varying mix of greys and a few flecks of faded black, and some parts already white.
Cas sighed, as he drummed his fingers against the side of his rocking chair, hoping to attract the attention of a nearby nursing home employee, if anything.
The woman who was standing by the door, watching Castiel, saw him but did not move from her slouched position to go attend to him.
Castiel honestly didn't care.
He'd find one way eventually to get out of this miserable place.
The woman who had light brown hair, almost like the colour of coffee when you put enough milk or cream into it, was wearing turquoise scrubs and ugly off-white nurse's shoes.
Cas didn't care much for her, or the way she constantly followed him around, watching him.
At most, all he cared about was getting out of there, forever.
But, when the woman whose name was Linda asked him what he was thinking about, Cas' mind suddenly went completely blank, and he couldn't remember what he was about to say.
So, his mouth fell open, stupidly.
Having no clue how to respond to her question, or even what was going on.
Linda sighed, arms crossed over her chest, her greyish eyes sad-looking.
"C'mon Castiel, I think it's time that you went to bed."
He nodded weakly, having no reason at all in his mind, to disagree with her.
Linda helped him into bed, his frail weak body, shuddering from the slight chill in the room.
"Too cold?", she asked, voice concerned.
Castiel tried to nod again, but nothing happened.
Instead, he gazed up at her with a deflated sad look.
She bit her lip and smiled, understandingly.
"Right. I'll just close the door then. Do you need anything else?"
Cas didn't respond, as Linda whispered a 'goodnight' to him, closing the door behind her, softly.
Eventfully, Castiel fell into a some-what decent sleep, though he had no clue how, and thought listlessly of the past.
Before, he'd came to stay here.
Sadly, he couldn't remember much.
It was all bits and pieces, which he couldn't manage to figure out.
Somehow, he hoped that someday he would finally remember...

The sky was a bright blue and the sun was shining, as Dean Winchester, sat outside in a lawn chair, a small leather bound book in his large rough hands.
He flipped through the pages fondly, as if they held some greater meaning to him, rather than just some story.
Truth was, they did.
But, only he knew that.
Dean looked up suddenly, when he saw that he was no longer alone.
He wiped his glasses on his shirt and put them back on, to see who was now standing there.
Dean smiled, when he saw who they were, his green eyes bright.
"Hi, Daddy.", said Mary, a young woman of about 26, who had blonde hair like Dean's mother and bright blue eyes, that sparkled in the afternoon sunlight.
"Hey, Princess.", Dean said to her, placing the book onto the vacant lawn chair beside him.
Behind her, he saw his son John, slightly younger than Mary by 2 years, he was carrying a black leather briefcase, hair a dark brownish colour, almost black.
His eyes were green like his father's.
"Hey, Dad.", John replied, waving at Dean and smiling.
Dean chuckled, extending one of his hands to his son, and shaking it firmly.
"Hey, kiddo."
Then, to John's right, stood Dean's youngest child.
She was not as old as her brother and sister were, but she was still a big part of their family.
"Hey, Angel.", Dean said, addressing Anna, who was about 15 or so.
"Hi, Dad.", Anna replied, her eyes as usual, glued to her phone.
Mary made a strange noise in the back of her throat, and John grabbed the phone from Anna.
"Hey! Give that back! I wasn't finished with it yet!"
John sighed, slipping her phone into his suit pocket.
"You can play 'Flappy Bird' later. Right now, we're visiting Dad."
Mary nodded, giving her father an apologetic smile.
Then, John asked it.
The question that was often brought up during their visits with their father.
"How's Dad doing? Any change?"
Dean sighed, shaking his head, and running his fingers through his greying hair.
"No, there's no change. The doctors are pretty much positive that he'll remain like this.", his voice was rough, like sandpaper being rubbed across a plank of wood.
"Have you visited him, recently?", Mary asked, eyes filled with concern for her father.
Dean nodded, one hand going back to rest on top of the leather bound book.
"Yeah, the other night. He threw a chair at me. Thought I was a robber or something. His nurse Linda, made me leave after that, telling me to stop upsetting him."
Anna's eyes were filling up with tears, as she heard Dean's words.
She could still remember life before the diagnosis, when both her parents had been okay and they all had lived together in that gigantic three-story house, that they had recently sold less than a year ago.
Now, if she wanted to see them, she had to go to the nursing home to do so.
This also meant, that they couldn't drive her to school, or take her out to dinner in their old 1967 Chevy Impala anymore.
It also meant, that she had to live with her uncle Sam and aunt Jessica, because both her brother and sister had full-time jobs.
Mary, worked in government, with taxes and stuff.
While John, worked at a law firm in California as a lawyer like his uncle Sam had wanted to do, but ended up in some other line of work.
After they talked, the little Winchester family all had dinner together in a small room off the dining hall, because they weren't allowed to eat with the other residents.
The conversations after that, were kept normal so, as not to upset their father and also, so that they too did not get upset.
When they left later that evening, Dean watched them from the window in his room.
Watched as they all piled into Mary's small silver Mercedes Benz, Anna walking with her head down, eyes once again glued to her phone.
He smiled, as he watched them pull out of the parking lot, the glow of the car's headlights slowly decreasing, as they disappeared down the road.
Then, Dean got into bed and tried to sleep, but with the traffic whizzing by and his memories of Cas clouding his thoughts, it was a failed attempt.

As Castiel was sitting outside the next day, a strange man suddenly walked up to him, a leather bound book under his arm.
He had no idea who this man was or why he was bothering him right now.
The man who had greying hair smiled and took a seat right beside Cas in one of the lawn chairs.
"Hey, how's it going?"
Cas didn't respond for a moment, then he sighed.
"Terrible. They won't let me leave this miserable place!"
Dean laughed, trying not to tear up as he thought of how much Cas had hated being cooped up in close-quarters.
He was glad to see, that his husband was still the same, if in only a few small ways.
"Mind if I read you a story?", he asked, glancing quickly across at Castiel, who had his face scrunched up in what Dean assumed was a look of utter concentration.
Cas nodded weakly, lying slowly back in his chair.
Dean watched as he closed his beautiful dull blue eyes, and began to softly hum to himself.
"I wish, I could remember how it goes.", he muttered sadly.
Dean smiled at Cas and opened up the leather bound book, turning the crisp white pages.
He felt his heart speed up, as he thought of the past.
Thought of the memories within the pages.
If only Cas could remember.
He thought, sadly.
If only he knew, who he was.
Who Dean was.
He sighed once more, before he began to read.
"Many, many, years ago, there lived a man named Castiel Novak. He had dark brownish hair that could be easily mistaken for black and eyes that were bluer than the ocean. He lived in a big house with his family. Michael, Lucifer, Gabriel, Hael, Rachel, Zachariah, and his parents Angela and Chuck. They were a well to do family, who always went to church on Sunday, and all the town events and county fairs. The day he met Dean Winchester, Cas was at a local county fair with his family and friends. It was the very beginning of summer and everyone at Cas' high school had just finished their senior year. Now, they had exactly 2 months, before they would either sign up for college or get a decent job. Castiel had already made up his mind, he was going to be a doctor and help people. Now, back to the story. You see, Cas had no idea that today was going to be one of the most significant days of his life. It wasn't like he knew in advance or anything. That's why, when they met Dean and Castiel, it was so unlikely. So, foreign. But, nonetheless it happened. And, here's how it went..."
