I'm looking for a fic where Kurt and Blaine are together throughout history in a series of multiple AU's. I believe each scenario ended with the same line until they meet on the Dalton staircase and it changed but I'm not sure. At one point, Kurt is studying art under Blaine and they are together in secret. They get into a fight and Blaine sends Kurt away. It isn't until a few years later that Kurt goes back to visit and learns that Blaine was dying and he didn't want Kurt to be there when he passed away.
Thank you in advance for the help!
