Blaine:
The bell rang and it was time for English, Blaine closed his locker, pulled his books into his chest and turned around to start walking to class as he noticed Kurt walking down the hall, towards him - he had a minor inward panic but tried to play it cool. "HEY KURT" Blaine said in a very high pitched scream as Kurt walked past, "uh, hey Blaine" Kurt responded with a puzzled expression.
Blaine felt insanely stupid but he sneakily turned his head to have one last look at Kurt, he could never help himself, he was so perfect. Blaine loved the way he walked, the way he dressed, his cologne, his eyes and his smile, he could get lost in his smile and he often found himself being caught staring lovingly at his lips - those were awkward moments.
As Blaine stood there daydreaming in the hallway daydreaming about Kurt he felt a sudden tap on his left shoulder that made him jump and quickly turn around - no one there, he then turned to his right and Sam was standing,
"Hey buddy, you okay?" Sam said trying to make eye contact with Blaine but he was somewhere else "Blaine?" he tried again giving his shoulder a gently shake.
Blaine then realized Sam was talking "uh, no, uh, yeah, yeah, im good, whats up?"
"You're so late for class, I knew you were around so i offered to come and find you" Sam said with a smile on his face, a smile that used to melt Blaine's heart but not so much lately. "Come on" he continued grabbing Blaine's arm and dragging him down the hall and through a small open doorway.
Kurt:
Kurt strolled through the corridors at Mckinley, always looking so elegant, always wearing his outrageous outfits that no one quite understood.
This day he had gone for a cute little black number consisting of black skinny jeans with black cardigan, little bit of white from his shirt underneath peaking out and his very shiny black boots.
When the ball rang for his next class he starting picking up his pace to walk down the hall, Kurt wasn't one for being late, he noticed Blaine turn around at his locker and they caught eye-contact for a split second "HEY KURT" he shouted? and Kurt replied with a softly spoken "uh, hey Blaine" and kept walking, all the while wondering why Blaine just screamed.
He had always liked Blaine but recently he had been acting weird, Kurt wondered why, as he sat in class he couldn't take his mind off it and then he knew he had to find out what was going on, they were friends, right? They went to Glee together, they'd sang duets together and in Kurt's mind that made them friends.
