I remember Kurt was in the Glee club. One day when he was sitting in the cafeteria a new kid in a letterman jacket (Blaine) came up to him and asked him out.
Kurt said no and got really angry because he thought Blaine was a jock and it was some kind of trick.
Later, Kurt is sitting in the bleachers at one of McKinley's football games, and I think Mercedes is with him? And Blaine came running on to the field with the Cheerios because he's on the squad and managed to talk Sue into letting him have a letterman jacket even though he was new. Blaine came up to Kurt and gave him the jacket for the game and asked him out again, but this time Kurt said yes. He also felt really bad about jumping to conclusions last time Blaine asked.
These bits may be from another fic, but I'm pretty sure it's the same one...
Blaine and Kurt start dating and I think Blaine does gymnastics and that's why he joined the Cheerios? Because McKinley doesn't have a gymnastics team.
Also, their first date is a disaster. Like, Blaine's car breaks down in the rain and Kurt has to fix it and then I think Blaine loses his wallet?
I hope that's enough info! Thanks in advance if anyone knows what I'm talking about!
