One day, a strange and exuberant transfer student, Aozakura Yuji, appears and takes an interest in Mikoto. He's determined to start a flower arrangement club, but with a twist: he wants to photograph beautiful girls arranged with flowers. He first pursues Mikoto, both for her beauty and because he bears the same flower markings as she does. After he photographs her for a promotional poster, everyone at school can see the beauty of Mikoto and her flower markings. Will Aozakura's flower arrangement club succeed? Is this the start of a new high school life for Mikoto? (Source: MangaHelpers)
