From Obsession:
Serge Battour, son of a gypsy prostitute and a count arrives to the Lacomblade academy, wanting to follow his father's footsteps and become a famous pianist. 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?
