The Wallflower Vol. 25 (manga)

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?

Includes a bonus manga by Tomoko Hayakawa and lots of additional goodies!
