Twisted Fate by Mrs Criss 2012
Kurt and Blaine have been best friends since meeting on the Dalton staircase 13 years ago. Kurt is about to get married and Blaine- as ever- is the sure and steadfast presence right by his side. But does fate have other ideas?
These are sorta similar, and I think you’ll enjoy them:

A Perfect Collision Verse by @fictionallylost
Kurt is a New York writer living in London, UK. He loves his life, surrounded by everything he could want but is still a little…lonely? He’s on his way home from work, sitting in a sea of awful London city traffic when he literally bumps into somebody who suddenly makes him a little less lonely.
Rocking Horse Ranch by @hkvoyage
Kurt has been working hard all year, and has earned a well-deserved break. He joins his family for the Christmas and New Year holidays at Rocking Horse Ranch, just north of New York City.
