In the Japanese version of the game, you could date not only the girls in the game, but also a male side character. This was removed for the American and European releases of the game.
This game combines the more traditional Japanese RPG elements with those of a dating sim. Further, a part of the game was removed for the American version. This portion of the game had the main character marrying the girl of his choice. Since the character and all the female characters were roughly 14-17, this obviously didn't sit well.
