Then it leads to blaine trying to win kurt back with the help of santana and brittany, who he takes with them to his photoshoots and things like that.
I'm pretty sure it was on ff.net as well.
I think (if it's the same fic) I remember later on when blaine and brittana are doing a livestream and talking about kurt, kurt rings blaine up.
I also remember kurt being in a lesson (at college/uni) and everyone talking about blaine anderson but kurt obviously isnt a fan.
EDIT: fic is What Kind Of Fool by Wings Of The Dreamer
