The wallflower

"After the gorgeous Kyohei kisses her, the anxious and awkward Sunako becomes convinced that it was harassment. She gets revenge by putting a curse on Kyohei, but when he becomes severely ill, it appears that her curse went too far. Only a kiss from Sunako can break the curse, but can she finally admit that she really does care about him? Or will her penchant for darkness be his true downfall?"--Amazon.com.
