I'm looking for this fic: Kurt calls Blaine and tells him he is transfering to Dalton. I don't remember why but Blaine gets angry at him and ends the call. Kurt starts crying and Finn is there trying to comfort him. Some time later, Blaine arrives and when he sees Kurt crying he apologizes to Kurt.
I'm pretty sure it's a Klaine fic because it's my obsession of the moment.
Does it ring any bells?
EDIT: FOUND all by my little self, it's All It Takes, here is the link if someone is interested
