because unlike your typical h-game (do you like horny bunnies?), this one has a good story (such as kana ~little sister~, crescendo, and private nurse).
yume miru kusuri's main theme is underlying the problems in the present day, where bullying, drugs and interpersonal problems exist in pretty much most high schools. so you play the game as a guy trying to help these problematic people recover.
just download the game, its all over bittorent. a quick google of the game title "yume miru kusuri" lists so many torrent links. look for a release by the group named "fasiso". they're god.
