Sherlock grimaced. His suit was ugly, his hair was awful, his bloody tie wasn't sitting right, and the bouquet he held in his hand was almost depressingly wilted. On any other occasion, he would have tossed the flowers in the rubbish bin, stripped off his clothes, and sulked about in his dressing gown for an hour or two. 

Well, he very well couldn't do that standing in the middle of John's waiting room. Damn the stupid man for insisting that he had to spend Valentine's Day working. Why on earth would the idiot presume that Sherlock wouldn't be interested in celebrating Valentine's Day with his dearly beloved?

Probably because i'm not interested in such meaningless frivolities,  thought Sherlock. But damn it all if he didn't feel just a tiny bit bad seeing all the couples in the streets, and wondering if John felt left out.

Stupid, stupid brain. Why couldn't you just leave it alone? Now you're standing here like an idiot.

But...I couldn't leave it alone...

It's John.

Sherlock was anxiously pondering these things, when his name broke him out of his reverie.

"Sherlock? What are you doing here? Did something happen?"

The sight of John's face with confusion etched across it in the most endearing of ways made Sherlock's heart skip a beat.

The sight of John in his doctor's uniform made something else skip a beat.

Sherlock pushed his arousal down. He cleared his throat, and hoped to whatever being existed that this wouldn't come out sounding stupid.

"John. John Watson. Um...you are...we have been...you have...I...."

John grinned, leaned up, and pressed the shortest of kisses on Sherlocks lips. He blushed, and reached for Sherlock's hand. 

"Better?"

Sherlock smiled. John always knew what to do.

"Better. I wanted to come and...surprise you, on the occasion of St. Valentine's Day, considering you have been my significant other for a year now. I hope I have not disrupted your work?"

John grinned like he'd just been given a knighthood.

"Nope. Thank you for the flowers! Assuming they're for me, of course." He winked playfully at Sherlock. 

Sherlock raised an eyebrow curiously.

"Do you really think that I am romantically attached with any one else? Because I'm-"

John chuckled. Of course this insanely clever man wouldn't understand a bit of teasing. He reached up and cupped Sherlock's cheek, kissing him again, gently.

"Just teasing. I love you."

As Sherlock wrapped his arms around John, he realized that he was absolutely besotted with his brave, clever, beautiful army doctor. He supposed his army doctor was absolutely besotted right back. 

"I love you too, John" He murmured. "I always have."
