There is a saying that if you find a Japanese maple leaf with eight tips you will find everlasting love. A popular high school actress is now making a film about that legend at the main character's high school, who in turn has a crush on her. One day after school he runs into her and helps her escape from some pursuing staff members. It turns out that since she started acting right after middle school she hasn't had any experience with love and that is hurting the production of the movie. So to get some experience with love she invites him out on a date.

Volume 1: Koisome Momiji (pilot)
Volume 2: FamiDol!

On his first day of transferring to a new high school, a loner named Mori Buntarou, is cajoled by a classmate into climbing the school building. Despite knowing that one misstep could send him spiraling to his death, he moves forward, and upon finally reaching the top, Mori experiences a sense of fulfillment. That feeling, which seems to be telling him, "You're alive!" gives birth to an adrenaline for rock-climbing.
