Basically, you have about three and an half months to finish the game with one girl. Each day, you start out at school and you have a parameter with three sections: Studies, Athletics, and Art. Depending on how you build up this parameter and how you interact with the characters, the story will change. You also receive love points if you answers questions by the girls you interact with correctly. You do not freely move in this game, it directs you by your parameter and how you answer questions with the girls. You can choose which girl you want to finish the game with by using that method. You also earn money and you have a meter that tells you how tired you are.
