So guys, here is a quick Story that came to my head while I was sitting in Bio-pharmaceutical Science one day, listening to my lecturer go on about mRNA.
I don't know how mRNA relates to this but the story wouldn't leave me alone. Luckily my feverish writing kept my lecturer happy, thinking I was taking notes! I hope you enjoy this!
I enjoyed writing it.
I have left my female unidentified because I want to let you picture who Sirius may end up with. I could be anyone, canon or OC. Also, If I ever go through with "The young..." I want it to fit in to this.
Disclaimer: Characters do not belong to me. Even my unidentified female.

She saw Sirius differently to how other people saw him. Even his closest friends. She knew everyone else thought he was beautiful for his strong jaw, his defined abs and his tall, lean body but she She more. She saw his eyes- or rather- through his eyes. Those beautiful grey eyes that seemed to change colour with the reflection of surrounding light.

She saw his soul and how much he'd been hurt. She knew of his mother's beatings and the invisible scars they had left. She knew how much happier he had been since the day he arrived at the Potters.

She knew the different demeanour he expressed through his eyes.

His delight when he gave a bludger a clean whack towards a member of the other team or when they served treacle tart at Halloween or Christmas.

His pride after he completed a piece of transfiguration homework that he knew would receive a good grade. Only, She was the soul person who knew of this one.

She knew that when his eyebrows dropped in the direction of the Slytherin table, he was looking at his brother Regulus who was reading a letter from home, or chatting secretively to one of the 'future death eaters' or so James called them.

She knew when he was about to cry, another thing that only she had witnessed. His lips could be pursed tightly and his eyes wouldn't focus on anything in particular but they would be still. After about thirty seconds of this intense look, if it could not be quenched, he would dart from the room, proclaiming something ridiculous and false before finding a corner just for himself.

She enjoyed looking at his relaxed eyes, his lids hung lazily over his eyeballs, almost as if he was going asleep, but in reality, he was just content. As if nothing bad could possibly happen.

She loved it when his eyes would barely stay open even with all of his effort. He'd try with all his might, lying beside her to keep up the conversation but destined to fail. His eyes would drop and his speech would slur and soon fade into snores. She'd lye there awake, her palm on his cheek, watching him sleep.

She knew the flicker in his eyes when he was about to snap. She knew she had about fifteen seconds to calm him before he jumped on whoever angered him or storm out.

She loved how she knew him through his eyes. It made her feel a connection that could not be severed.

"Sirius," She would nuzzle her face into his chest. "Sing me a song,"

Sirius would start humming the tune of a song but it wasn't until the chorus that he would sing the lyrics. He sang lowly, deeply, in a hypnotising way. He wouldn't sing to anybody. That was reserved just for Her. And it made her feel absolutely specialised.

She didn't even know if they were real songs half of the time or if he made them up as he went along. She never wanted to know either, as to Her, they were Her songs.

"You are staying here quite a bit," he whispered, his brows furrowed deeply into the centre of his forehead. She looked around the small bedroom, half of its content belonged to Her.

"Is that a problem," she asked, releasing her arms from around his waist. She sat up in the bed and he followed, moving his hand to her back.

"No. I just think that maybe you should always stay here."

"Don't be silly, my parent's would wonder where I am all the time. And I'd have to go to work, I can't lock myself in here."

"I mean move in here, dummy," he chuckled, moving his hand to the back of her head, stroking her long hair. She stared at him for a long moment, checking his eyes. They were full of earnestness.

"You're not joking, are you." she mumbled, turning to face him, pulling the covers up around her body. "Sirius, I can't. You know what my father is like, he wouldn't let me move in with a man until I am married. And my mother would go absolutely spare! I'm a virgin, remember," Her widened her eyes, trying to hide a smile.

"You parent's like me..."

"That's not the point..."

"I think they'd like me as a son in law..."

"Wait what?"

"I want to marry you," he let his head fall slightly, looking up at her with his best puppy dog eyes.

"Really? Like, really really?" Her heart began to pound in her chest and every objection she had to moving in with him and flown out the window.

"Why not," he smiled, taking her hand. She moved over him, straddling him and pressing her lips to his.

"Sirius Black, I cannot think of a single reason not to marry you."

"So you will? That's a yes?"

"Yes, of course I'll marry you, you great oaf," she laughed before kissing him again.

"I love you," he murdered against her lips.

"I love you too," She replied before she was flipped onto her back.

"Do you think we should keep this between us for now? Until we plan a bit more," She asked Sirius, who was lying between her legs, cheek pressed against her stomach.

"I just did that, and you're thinking about a wedding? I'm losing my touch. I used to render you speechless." he moaned, moving up the bed to join her at the pillow. "I have to tell James,"

"Well there's no denying that. I'm surprised you didn't mirror him before we had sex," she laughed.

"I have both the mirrors. One is faulty, trying to fix it. Besides, James is minding your ring," he smiled shyly.

"My ring?"

"Did you think I'd propose to you without having a ring? I actually planned to do this properly but I couldn't hold it in any longer..."

"Who thought that the notorious Sirius Black would ever be tamed by a silly little half-blood like me," She mused. "I wonder what my mum will say,"

"When do you want to get married," he asked, wrapping his arms around her, pulling her in tighter.

"Christmas," she smiled. "Christmas eve,"

"What about new years? Christmas is with James and Lily,"

"Ah yes. For a bloke who ran from tradition his whole life, you seem very eager to keep up new ones."

"New ones make sense. Old ones don't. Like beheading elves."

"Ruining the mood, love." She laughed. "New years," she agreed before dozing off.
