I'm looking for an older fic today.
I remember it's Klaine, where Blaine is kicked out of his family home.
He moves in with the Hummels, paying rent. He gets a summer job on a construction site, as he wants to be an engineer. He says something to the effect of he wants to see how everything works so that he can plan for the construction people as well as the design when he goes for the interview.
He gets a scholarship that covers a large amount of his college fees and he will gain access to a trust fund when he turns 18/21.
That's about all I can remember. Any help would be appreciated.
