Megane wa Ai no Ichibu desu.

No one can deny that Yuki and Toma are head over heels in love! One day, they encounter a pair of cursed glasses that change their wearer's personality. The once-sweet-and-gentle Toma turns into an angry guy who has a hard time expressing himself. Yuki, who's kind of a pushover, finds out there's one way to lift the curse, but is he up to it…!?
