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!

With Yoh's parents out of town, it's up to Haruna to take care of Yoh when he becomes sick. No parents around, huh? Hmm... But Haruna wouldn't dream of taking advantage of this convenient situation...or would she?
