High School Debut 3-in-1 edition 1 collects volumes 1-3 and features story and art by Kazune Kawahara.

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 help, Haruna starts to discover all sorts of things: how to dress better, which guys to avoid, and what it feels like to fall in love for the first time. Haruna's foray into love has its ups and downs, but nothing's going to prepare her for when she actually lands herself a boyfriend!
