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!
Haruna becomes worried when she sees Yoh hanging out with an unattractive classmate. (Yoh does seem to have strange taste in women after all...) She has good reason for feeling uneasy--it looks like this girl really does want to sabotage their relationship!
