Kyle Broflovski hated rainbows. He hated that they signified peace, serenity, beauty… in short, everything that he desperately wanted but could never truly have. His life was never peaceful. At home, his father had walked out two years ago, spitting over his shoulder that his mother was a "self-centered conceited slut of a bitch" and that he didn't give a damn about Kyle. Beauty was another story altogether. Each morning, Kyle put on his face. He would spend an hour in front of the mirror, fixing, rearranging, styling, only to take it all off, unsatisfied, and start over. His looks, his beauty, even his silky red locks of hair- it was all fake.
Kyle hated the rainbow sign. It signified gays, lesbians, bisexuals… whatever the fuck you wanted to call it, it was a man loving a man or a woman loving a woman. Just like Kyle. He hated that it called on every part of him that his friends would hate most. That it reminded him so desperately of his once-love, Stan. That Stan was now in love with a girl named Wendy, and had forgotten about their hidden whirlwind of romance.
Kyle loved the color red. It showed power, anger, control- everything he had locked inside. It was the same color as the blood he drew from his body with each quick swipe of a knife. The same color as the scars on his wrists, permanent and overlapping from the many openings and closings. From wound, to heal, and then back again, Kyle would make each line stay, no matter how long it took.
Kyle hated the color blue. It represented sadness, unhappiness, broken-heartedness, and a forgotten love. It was Stan's favorite color, now destined to make Kyle forever angry. It showed in a person's eyes when they were sad. It showed in Kyle's eyes when he was sad. But that was what sunglasses were for.
Kyle was a very unhappy person. A very self-destructive person. There are so many things wrong with him. But only in his eyes. To the world at large, Kyle is thin, beautiful, perfect. To Kyle, he is fat, ugly, a terrible friend, and a mistake. So he just stopped. Stopped eating, to lose weight. Stopped listening, to shield himself from what he had long-ago convinced herself were remarks about his terrible looks. Stopped trying. Stopped caring if he lived, and tried to kill himself.
Kyle completely gave up. Kyle ruined his life. So Kyle ran away, not seen for months on end, until one day- one day that nobody in South Park could force out of their minds. Kyle had done so much worse than run away- he had hung himself by Starks pond. Forever destined to live in peoples' minds, the same way he so wished he didn't have to. Goodbye, Kyle.
