i'm not really sure but i thought it was a Kurt/Blaine endgame story,
What i still remember from that story is that Kurt goes to a psychologist, he's in his 20's, and at one point Kurt is in a bar and the psychologist is there also, and they kind of realise that they like each other. The psychologist isn't Blaine btw! it;s an OC.
Kurt where he's endgame with an OC.
