I saw we can order the bonus content version, but no details about what is included, anyone can enlighten me? (Quickly because i want to start playing :D)

Yes sorry, I always forget to write in the page! For all my games the "bonus content" is a file that includes wallpaper/extra artwork and the soundtrack in mp3. But the game itself is identical.

So no additional romances? Damn.

Or secret steamy scenes that couldn't be included for the Steam folks?
