But now that she's going to high school, Haruna decides to put all of her energy towards getting a boyfriend and having the high school romance of a lifetime. To help in her quest, she enlists cute upperclassman Yoh Komiyama to coach her as she eschews her jock tendencies and turns herself into the kind of girl who can catch a guy. Yoh agrees, with one catch: Haruna had better not fall for him!

    After all they're not just learning about the world, but about themselves too.

    To satiate this need (and keep her classmates from finding out), she has enlisted Hana Harumi, whose perfectly sized and shaped bust may just be everything Chiaki's ever wanted...Will their odd partnership bloom into a bosom bond like no other?
