Specific College Klaine fic

FOUND!: Labels by klaineanummel on AO3.

I'm looking for this fic that was most likely on AO3 where Kurt and Blaine meet in college, and Kurt had never realized he was attracted to men until then. In a later chapter or a sequel, Kurt overhears Rachel assuming he's gay and he is upset she is trying to label him when he doesn't even know his own sexual identity.
