Even Then, Especially Now by @kuhlaine
Some would say it’s fate that brings Kurt Hummel and Blaine Anderson together during their freshman year at NYADA. They’re halves of a whole, peas in a pod, birds of a feather — two people who were destined to find one another. When a series of misunderstandings lead them to pursue relationships with other people, they’ll need more than fate to find their way back to one another.
Someone Like You by iconicklaine
Kurt and Blaine keep up their very own version of "When Harry Met Sally" for years, a friendship fraught with sexual tension and longing, until the agendas of Adele (yes, THE Adele), a bored NY socialite and a super-sweet hetero couple bring our boys together. The only problem is... they're both in committed relationships.
Wandering Around Back to You by munchkinpandas
From strangers to floormates to best friends, to roommates, to the closest two people can be. This is the story of two boys who found each other and never let go.
Courage by aslongastherearestarsaboveyou
AU where Kurt and Blaine's first kiss doesn't quite happen and it leads to them living different lives, both wanting each other but having life get in the way all too often. A story about courage, and the lack of it.
