Blaine loved New York. Like really loved New York. He loved the way the city thrummed under his feet, the way it breathed. He loved how loud it was and how alive. He loved the people he met that were new and interesting. He loved that there was nothing Ohio about New York. He loved that no one really knew him and yet they could see he was just like so many others around him. He loved it all.
But at the same time, he hated New York. He hated that it was so fucking big. He had been in the city for seven years, and he looked everywhere he went, but he never saw the person he was looking for.
If anyone asked, Blaine had moved to New York after graduating because of college music programs. But Blaine had to pretend he didn't see all his friends roll their eyes at his dumb excuse. Everyone knew the real reason Blaine was going to New York.
It was no secret to anyone at Dalton that Kurt was going to go to New York when they had graduated. ( What was a secret was why he had let, but Blaine sulking around like a forlorn and profoundly guilty puppy had kinda solved that one.) So when Blaine had announced that he was enrolled in NYU, everyone just pretended they didn't hear that sentence as "I'm going to follow Kurt and find him and love him until we die".
Because in Blaine's mind, that's what he was doing in New York. He was going to find Kurt, make him understand what had really happened that night, marry him and live happily ever after. Blaine even had the speech all mapped out (of course, over the years his introspection had grown and so had the speech, especially the explaining part) and now, all he needed was to find Kurt and everything would be okay.
But New York had failed him for seven years. He never stopped looking, of course, or hoping; but in those seven years, Blaine had stopped letting his life revolve around Kurt. He wasn't over him, by any means, but Blaine had somewhat resigned himself to the fact that his life was now meaningless sex and heart-wrenching songs. It was purgatory, always waiting for something to happen, but he didn't mind.
Well, he didn't mind until one night, when he was setting up for his weekly gig at his favourite bar, Kurt Hummel pushed the door open and sauntered back into his life.
He watches him walk to the bar, plonk himself down, and order what looks like a vodka tonic. Blaine just watches, unable to do anything else. The speech he's been planning for ten years has fallen straight out of his head and all he can do is watch the bob of Kurt's throat as he drinks.
It's only when the crowd starts yelling that Blaine realises he stepped back too far snd the sharp claw of static is deafening them all. The sound of feedback that is now make Kurt look up and right at him.
For the first time in ten years, since the night he broke both their hearts, Kurt and Blaine look each other straight in the eye and it breaks the paralysis over both of them.
Kurt finishes his drink and orders another one in quick succession, avoiding looking at Blaine studiously.
Well, Blaine thinks, i'll just have to make him look.
He bends over the mic. "Hello, i'm Blaine Anderson and this is 'This Boy's in Love'."
It's one of his usual songs, and the audience at the bar usually love it, but tonight he's playing it for a completely different reason. A reason that just happens to be at the bar on his third drink.

[This time fight fire with fire,
Coz baby tonight the world belongs to you and i.

This boy's in love,
Love.
This boy's in love,
Under city,
Under city lights.

This town, these streets,
Your friends,
You'll never see this place again.
You'll think about it,
Now and then,
You'll never see our face again.]

He ends to a decent amount of applause and yet another ordered drink from Kurt. Blaine was definitely getting to him. He searches his mind for the next song and it comes to him, glaringly obvious.

[When I see your smile
The tears roll down my face,
I can't replace.
And now that i'm strong
I have figured out,
How this world turns cold,
And it breaks through my soul,
And i know i'll find,
Deep inside me,
I can be the one.
I will never let you fall,
I'll stand up with you forever.
I'll be there for you through it all, even if saving you sends me to heaven.]

Over at the bar, Kurt seems to be fighting with the bartender over whether or not he needs another drink. Blaine only had one song left before the other regular came and took over. It was time for the coup de grace.

[I knew, I knew, I’d lose you
You’ll always be special to me

And I remember all the
Things we once shared
Watching tv movies on
The living room armchair

But they say it will work out fine
Was it all a waste of time
Cause I knew, I knew, I’d lose you

You’ll always be special to me

Will I forget in time
You said I was on your mind
There’s no need to argue
No need to argue anymore
There’s no need to argue anymore]

It was the closest his setlist came to an apology, and he suddenly felt himself wishing he could just hijack the mic and give Kurt the speech, but the girl who was up next was already on stage, ushering him off.
Blaine tripped off the stage and headed to the bar.
"Kurt." The word ripped itself from his throat, and it sounded coarse and a little like a moan. He looked up, and all that was written across his face was despair. Blaine's heart broke with every tear that slide down Kurt's perfect face.
"Kurt, Kurt. Kurt." Over and over, Blaine said his name. It was his apologies and his declarations of love and his own self loathing and it was all Kurt's name.
Suddenly Kurt was pulling him into a fierce biting kiss and whispering "take me home."
