John Watson was buying milk on February 14 2011 when his phone buzzed.

Dinner? -SH

Starving. Little place on the corner? -JW

Done. Meet there once finished. -SH

He payed for the milk and various other things and walked down to the Italian restaurant on the corner of Blexley Road. Sherlock was waiting at a table for him.

'Hi, sorry I took so long. Long line at the shop' John said sitting down opposite Sherlock. 'Not a problem. Hungry?' Sherlock replied handing him a menu 'You needn't bother looking I've already ordered.' John shook his head, he couldn't help but notice Sherlock's hair, it was very nice, he wanted to run his hands through it. 'What, stop it John' he told himself. The food arrived and he noticed Sherlock was eating. 'I thought digestion slowed you down or something?' 'It does, however, we aren't working and I am hungry, so I shall eat.' Sherlock replied matter-o-factly. John reached into the grocery bag and pulled out a nicely wrapped box. 'Happy Valentine's Day' John handed Sherlock the box. He looked stunned, 'I didn't know we were doing, gifts.' 'Well no, it's just something, not a big deal, not like, romantic.. I mean...' John replied 'Smooth!' He thought to himself. 'Romantic, no, no, just friends, right? Well, more than friends but.. You know... Like... Um, not romanic..' Sherlock stuttered. 'No, no,' John said 'I mean it could be but.. No, gah... Sorry.' Sherlock replied. John was shocked. Sherlock didn't have some clever remark or comeback. Sherlock was lost for words. Dinner passed without another word.

Sherlock hailed a taxi and they both climbed inside. About five minutes into the trip, Sherlock broke the award silence. 'John?' He asked 'Yeah?' John replied a little too eagerly 'I am sorry, about earlier, but I did mean it' Sherlock said 'Mean what?' John asked 'That we could be more than friends, if you would like...' Sherlock said. It was John's turn to be at a loss for words. 'Say something John.' Sherlock said 'John? Was that bad? I'm new to this. Did I do it wrong?' 'No, that was perfect.' John replied 'Sort of..' And he pressed his lips against Sherlock's and felt Sherlock take his hand. As they broke apart John looked into Sherlock's blue eyes, they were perfect. Sure Sherlock was a rude, arrogant, unpleasant sociopath but he was HIS rude, arrogant, unpleasant sociopath.

The taxi pulled up outside 221B Baker Street and the pair made their way inside. John pulled the door closed by the knocker, like he always did, he took Sherlock's hand and Sherlock pressed his lips against John's. John heard Mrs Hudson's door open. He knew she was watching but, for whatever reason, didn't pull away. Perhaps he didn't care any more. When they did break apart they ran upstairs to their apartment and John heard Mrs Hudson say 'I always knew it'. They'd get a million 'I told you so's and 'I always knew it's' from her in the morning but he didn't care. 'Goodnight Sherlock' John said and planted a kiss on his cheek. He went into his room and saw a card sitting on his pillow. He picked up the envelope and opened it. The card inside read;

Dear John

Thank you for being an excellent friend and putting up with, well, me. I am a very annoying flat mate with my passion for murder and the fact that I shoot the wall when I'm bored. I'm not sure why you haven't left yet. I can't work it out, I don't know and I hate not knowing. The only logical reason I can come up with is that you like it. So, I hope to continue the current arrangement and as a treat I'll buy the milk when we run out next.

From Sherlock

PS. Happy Valentines Day, John. I love you.

John was happy. He flopped onto his bed, it was true, Sherlock was an unbearable flatmate but John loved it at 221B Baker Street, the excitement, the adventure, the danger, the company. That was why he was still here. He loved it (and Sherlock) Everything was perfect.
