Karofsky couldn't believe that after watching the man of his dreams and fantasies reject him that he could still be in love with him, and his body quivered and broke out in a cold sweat that evening when he was alone.
He was alone.
The day after the incident, he saw Kurt coming toward him with some boy, just some kid walking behind him loyally, and he thought that he must be Kurt's boyfriend. That must be the reason he didn't want him; he already had someone better, which immediately hardened his heart and turned his face to iron. He looked away, made some harsh remarks, and made to push past, but the two of them blockaded him in a corner of the stairwell, and then proceeded to practically out him in front of all the passersby without any regard for his sanity, his self, his Solitary. He couldn't believe that Kurt would do something like that, something much more hurtful and dangerous than anything he'd ever put the smaller boy through. Sure, he called him names and shoved him, but he'd never made his friends hate him with a word, and if his friends had been around, Karofsky would have been shunned and sacrificed.
And still, after that, after jogging off coldly only to cry his heart out in the empty locker room's bathroom for all of 6th period, he still wanted Kurt more than anything. He felt that perhaps this was his judgment. If he could withstand this torment, this onslaught of emotions… perhaps he could withstand anything.
No one caught him crying, but later, after he'd found his resolve and left the bathroom, he made sure to avoid Kurt for the rest of the day and the rest of the week. He only had one heart to break, and if it was broken too many times or all at once, hell, it may never be the same again.
A week later, Karofsky found himself hiding behind an artwork display statue and watching Kurt walk into Glee Club. There, thinking of Glee, he thought of a way to make Kurt see that he was somebody, and maybe, just maybe, give him a chance to prove it.
He immediately drove home and got to work.
