Kurt and Blaine could easily not have met on a staircase in high school. They could have met a few years later in college instead.
This story is AU from within 2x06 («Never Been Kissed»), with many of the broad strokes of canon remaining except where I thought they would be different because of the AU or other factors. It takes place in Blaine's first year of college, starting about a year from now. There are some spoilers through 3x22 (“Goodbye”).
Fuller notes and the LJ master post for this story can be found here. Special thanks to intrepid beta and hand-holder stoney321, who made the best encouraging noises when I said “I've been thinking about who Kurt and Blaine might be if they hadn't found each other in high school” and who never stopped.
This story is now completely posted.
