It must be post college. Kurt is working as a stage actor and getting good roles.
There are a few OC's. One of them is a playwrite engaged to Rachel.
Sebastian lives and works in Boston, but he has to be in NYC once a month. He and Kurt develop a friendship and a f*ckbuddies kind of relationship. Both of them are reluctant to admit how much they actually care for each other because they are both scared of a long distance relationship.
Kurt gets an opportunity to do Shakespeare in Boston, so they get to spend weeks together instead of just a couple days.
At the end of each chapter there was a twitter entry from a fangirl of Kurt's that was following his stage career, and she would post about her Kurt sightings.
