Will Haruna's high school debut end up in heartbreak hotel?

Hapless Haruna needs help finding a boyfriend! After failing to win the eye of any guy in high school, Haruna enlists the help of cute upperclassman Yoh to coach her on how to make herself more appealing to the male species. Yoh agrees, with one catch: Haruna had better not fall for him!

A chance encounter on the train brings Haruna face-to-face with Yoh's ex-girlfriend. (Yes, the ex-girlfriend of "the beads incident" fame!) Yoh reassures Haruna that he doesn't want to get back together with his ex, but is that how he truly feels?
