Dean Winchester was a horrible person. It wasn't that was a particularly bad person, or that he was mean. But it Cas found that the most annoying thing about his perfection was that it wasn't annoying. Dean Winchester was a horrible person because he made Cas fall more and more in love with him every single day, and made Cas feel comfortable and safe and happier than he had ever been before. Cas sighed. Goddamn Dean giving him all these feelings he never asked for. Despite this, he couldn't help but smile as Dean traipsed through the living room in just a towel.

"Take a picture, it'll last longer."

Cas' shook his head as Dean spoke, realising that he'd been staring at Dean for a while now.

"Can you blame me?"

Dean smirked.

"No, I completely understand, but don't you have work to get to?"

Cas rolled his eyes.

"Unfortunately- don't you?"

"Nope."

Dean simply stated from the bedroom, pulling on a pair of underwear and a old Metallica shirt.

"And why is that, may I ask?"

Cas grinned at Dean's enthusiastic laziness.

"I figured, today's not really that important, I don't have any clients booked in, what's the point."

Cas sighed. Dean must have forgotten. It was their anniversary. It's not like he expected him to remember, but the fact that he dismissed the day completely just dropped a heavy weight on Cas' heart.

"Okay...I'm off to work now.."

Cas gave Dean a wave before heading out.

"Goodbye Cas."

Dean saluted from the sofa.

As soon as Cas shut the door behind him, Dean put his plan into action. He sprung from the sofa, scurrying to his bedroom and put on some jeans and a couple of plaid layers over his t shirt and rushed out of the door. He jumped into baby and drove to the next town- he didn't want Cas to know what he was up to.

He had arrived, and had to make sure everything was set up perfectly- this would take a while.

Despite all the smiling faces he saw entering and leaving the shop, Cas couldn't help but wear a frown on his face. He didn't expect Dean to remember their anniversary, and he certainly didn't need something special. Cas didn't understand why this bothered him so much.

He knew Dean. Although Dean seemed like a laid back guy, he took his commitments seriously. He didn't expect him to, but Dean would have remembered their anniversary. Something didn't seem right.

Dean was hiding something from him. Cas could sense it, Dean wasn't one to slack off work for no reason- he loved his job!

What possible reason could there be for Dean taking the day off, and forgetting their anniversary- was he trying to avoid Cas? Did he realise that he could do better?

These questions uncomfortably settled in Cas' mind, until, by the end of the day, they were seared into his brain; he was convinced that Dean no longer loved him.

Cas sighed as he arrived home from work, as he plodded up the stairs, he bit his lip in anticipation of seeing Dean again, knowing that Dean was going to end their relationship.

Cas' eyes widened at the sight that lay before him. Dean was standing by the door, in the sexiest suit known to man. He was holding a..a..pie? Cas rolled his eyes- of course he was.

Dean had a boyish grin on his face; what was he up to?

Dean greeted Cas with a deep kiss, pulling him closer. As he pulled away, Dean leaned closer, and gently whispered "Happy anniversary." Into Cas' ear.

"I thought you'd forgotten..."

Was all Cas could say, an overwhelming feeling of guilt washed over him- why did he doubt Dean?

Dean smiled.

"How could I ever? Come on, we're going for a ride."

Cas handed Dean a blindfold as they got into Baby.

"Why do I need a blindfold, what are we doing...recreating fifty shades or something."

Dean choked on the gulp of air that was stuck in his throat.

"Maybe later..."

Was all he could croak out. Cas chuckled, Dean still tried to be smooth.

Cas reluctantly put on the blindfold, and stepped out of the car, with Dean's hands wrapped around him. He was safe in these arms. Happy in these arms.

He bit his lip as Dean traced his fingers through his hair and undid the blindfold, while simultaneously placing a tender kiss on his neck.

"Open."

Dean said softly.

Cas opened his eyes, and was shocked at the array of green and blue flowers dotted around the room.

They were beautiful, but nothing could compare to Dean's eyes in that moment. His dilated pupils like pools of deep, mysterious darkness encapsulated in green. The kind of green that pushed its way through the piles of gritty snow to remind you that spring was coming. The kind of green that budded on the prisoners of winter, bringing life back to their branches. That churning, passionate green that the ocean turns during a storm. That colour of the forest after it rains. That green colour that brings hope and life no matter what has happened.

Dean was tense, but just one gaze into those eyes and he felt all his troubles melt away. The eyes that meant comfort and warmth. The eyes that made him feel like he mattered, that he was doing something right. The eyes that made him feel that life was worth living. The eyes that made his life complete. Beautiful blue eyes. The word blue didn't do them justice. His eyes were blue. Not the ordinary sky blue, or the colour of the paint flaking off of the old shed in the back of the field, or even the little flowers that spring up by the side of the road. His eyes were blue like the sea, crystal clear blue- shimmering and crashing and churning. Looking into his eyes you could hear the waves falling against the shore, see the foam flying into the air. His eyes were blue like the sky right before the sun disappears- dark rich indigo, with specks of wild colours here and there. His eyes were blue like that warm wool sweater that you put on when the air gets that chill- comfortable, warm, familiar. His eyes were that kind of blue.

Dean knew, these were the eyes he would want to stare into for the rest of his life.

"Castiel Novak," he began, getting down on one knee. "I used to think that I would never amount to anything. I would never do anything worthwhile. I would never find true happiness. And I was okay with that, for a while. But then I met you...you make me happier than I ever imagined was possible, and best of all, you make me feel like I deserve to be this happy, and despite everything in my life that's gone horribly wrong, I wouldn't change a thing, because I'm with you today. You're all I have, and you're all I need. And I want to spend the rest of my life, trying to make you feel the same way. Castiel Novak, will you marry me?"

"Dean," Cas replied, tears forming in his eyes. "You don't have to spend the rest of your life trying to make me feel the same way...I already do...but I'll marry you anyway.."

The pair chuckled, and through voice cracks, tears and broken speech, Dean slipped the ring he'd produced from his pocket onto Cas' finger.

Dean stood up, and wiped a stray tear from Cas' cheek, he leaned forward, cupping Cas' face as he kissed him tenderly, their lips moving in sync. Cas pulled away, smiling, and, gazing deep into Dean's eyes, mumbled.

"I love you, Dean Winchester."

"I love you too Castiel Novak."

"Technically I'll be a Winchester soon."

"Do you always have to correct me?"

The pair grinned at each other, they thought they could never be as happy as they were in this moment. The stared into each other's eyes, and leaned in for another kiss.

The couple lay on a bench, cuddling; their limbs were entangled and Dean was resting his head on Cas' chest. Cas placed a soft kiss on Dean's head.

They both wanted to spend the rest of their lives like this; quiet, comfortable, safe- together.
