You play the role of Narusawa Daisuke who is now living with your grandfather and just got transferred to a new high school and meets new people. From time to time you will switch perspectives from Daisuke to the girls so you can understand what they are thinking and more importantly how they are feeling deep inside their hearts. This means that not only will you make decisions for Daisuke but occasionally for the girls also.
