Sweet
Kyo never liked chocolate. He would eat it if forced, but never willingly, and he usually felt rather ill for a period afterward.
He remembered the first time he tried it, as a young child. He had never had candy of any sort before (his mother wouldn't let him have candy) and had never seen it before (his mother wouldn't let him watch television anymore) but the other kids (the ones who made fun of his hair) seemed to love the stuff.
Kyo's first instinct was to avoid it simply because his tormentors liked it, but it seemed to make them happy and Kyo desperately wanted to be happy too. People told him it tasted good.
One day he was offered a chocolate candy bar; solid milk chocolate in a foil wrapper. After getting help tearing the package open, Kyo took a bite.
It was crunchy, crumbly and flavorless. When Kyo was much younger, he had once put a birthday candle in his mouth.
The chocolate bar tasted like wax. Kyo spat it out in disgust, furious that he had been tricked into tasting such a vile thing.
And after the color finally returned to his vision, Kyo told himself that he wouldn't eat chocolate ever again.
Author's note: Chocolate itself is actually toxic to cats. Do not allow your cats to have it.
