In this place he meets a strange boy, Gilbert Cocteau. Gilbert is well known because of his promiscuity and evil behaviour, but this doesn't stop Serge trying to be friends with him and maybe something more... Can you hear the song of the wind between the trees in autumn? In 1979, this series was awarded the prestigious Shogakukan Manga Award for shounen/shoujo manga.
