Sherlock hated you so, so, so very much.

Christmas was in full swing in the 221B Apartment of Baker Street. You ran around entertaining guests unconsciously with your singing and laughter. John and Mrs Hudson, along with Molly, Lestrade, Mary and even Mycroft, all sat or stood in the living room drinking cups of tea, coffee or eggnog and chatting mindlessly. Sherlock, on the other hand, sat in a corner grumbling to himself.

"Sherlock! I haven't seen you the entire night!" You jumped up behind him, making him jump a little.

"(F/n), my dear, you've not seen me, because I do not care for Christmas. I've told you that already."

"Yeah but I figured you'd at least try to pretend you were enjoying yourself. Last year you at least played some carols on your violin. Even Mycroft is making an effort." You said gesturing to Mycroft, who was currently laughing along with Mrs Hudson.

"Well you obviously don't know me very well. And besides, you've been playing carols for the last month or so, so I'm sick of hearing them." He stated.

"Well, make your own version of them then? Please? Just do something." You pleaded, eyes wide like a puppy.

"No." Sherlock got up and began to storm away, you quickly following him.

"Please Sherlock, just one?" You were about to continue with your pleading, but John shouting 'aha' as loudly as he could stopped everyone in the room.

"Sherlock, (f/n), you finally, finally fell for it!" He called put, a huge grin on his face.

"What are you going on about John?" Sherlock sighed. John only smirked and pointed above us. Hanging on the doorframe above us was a small sprig of mistletoe. You flushed bright red and Sherlock rolled his eyes.

"You have to do it Sherlock, no ifs ands or buts." Sherlock glared at John before looking down at you, his eyes slightly softer but still laced with annoyance. He began to lean down and your cheeks turned redder and redder. Just as he was a mere inch from touching your lips, the doorbell rang and everyone groaned in frustration, except you and Sherlock.

"I'll get it!" You said pushing away from Sherlock and sprinting down stairs. When you reached the door and opened it, you were surprised to see who it was.

"Jim! Hi, how are you?" He laughed at your shocked expression and smiled, almost like a Cheshire Cat.

"It's Christmas and I wanted to see how you and your boyfriend were. Everything turn out ok?"

"Oh, yeah, we're fine now. But he's still refusing to be festive."

"Well~ we can't have that~. Here, I brung you both a gift. This should get him into the mood." Jim held out a bag, which you took.

"Aw~ thanks Jim, you really shouldn't have. I feel bad now, uh... did you want to come in?"

"No, no. Thank you, but I'm fine. You go enjoy your Christmas. Bye bye~"

"Oh! Ok, bye." You stood at the door for a moment after you'd closed it, a little scared to head back up stairs.

"(F/n)." You spun around, shocked to hear the voice behind you. Sherlock stood there, looking quite solemn. It took a second for you to notice his violin was in his hand. "Now before you say anything, don't get excited, I will not, I repeat not,  play anything for anyone upstairs, but I know how much Christmas means to you so just... just stand there and listen."

He held the violin up and positioned it under his chin. He begun to play and it took you a second, but you recognized the tune. 'All I want For Christmas Is You' by Mariah Carey, played a little less pop than the original and it gave it a more emotional feeling. The whole way through the song, Sherlock stared into your eyes. When he was finished, he simply stared into your eyes and walked towards you before leading you into Mrs Hudson's kitchen and moving close to the wall.

"Here should be about right." Was all he said before he leant down and kissed you. Your eyes, initially wide with shock, fluttered closed. He held you closer as he deepened the kiss, keeping it somewhat innocent but still conveying all his emotions to you. When you broke apart you were shocked, confused and crying a little, but overall, ecstatic and feeling better then you had ever before. You were the first to speak.

"Wha- what was that all about? And- and- kiss?" You stuttered out.

"Even if I don't like Christmas, or people, or celebrations and refuse to celebrate any of it, it doesn't really give me the right to ignore my girlfriend, or leave her feeling crappy, for lack of a better word, on her favorite day of the year." You would have stood speechless, if not for the lingering question.

"But, why did you bring me in here?"

"Well, you ran away up there, and just because there's a floor, or roof, in between, technically we're still under the mistletoe." Your face had never had to display so many emotions before. You were crying, blushing, smiling through pursed lips and shaking all at once. Eventually, every part of you agreed that jumping on him and hugging the air out of his poor body was the appropriate course of action.

"ThankyouthankyouthankyouIloveyouthankyouloveyousodamnmuchthankyouthankyou." (Thank you, I love you, love you so damn much) Was repeated over and over as you hugged him. He stood there, accepting the hug and patting your head until you calmed down enough to remember Jim's gift, which you were somehow still holding.

"Oh yeah, the guy from the park the other day dropped by and gave us this." You opened it to see two parcels wrapped up, one with (fave colour) ribbon and the other with a dark blue one.

"Here, this one's yours." You said handing Sherlock the dark blue wrapped one. After you'd both unwrapped them you found out they were 'ugly Christmas sweaters'. Yours was various shades of (colour) and had 'The Detective's Kitten' written on it. Sherlock's was dark blue and grey with 'The Kitten's Detective' across it. You smiled at them and pulled it over your head instantly, urging Sherlock to do the same. He did so, reluctantly, scowling the whole time. You ran upstairs, leaving Sherlock in the kitchen with a small lipstick stain of his cheek, excited to show everyone. Sherlock sighed and went to chuck the wrapping paper away before noticing a small note at the bottom.

"Hey Sherly,

Pay more attention to your things, or kittens might stray. Nice meeting her though, look forward to seeing you again. Merry Christmas, Mr Consulting Detective.

-J.M"

The note was tucked into his pocket before going up to his 'kitten', not realizing he'd forgotten about his 'present' from Jim.
