Primary Step

Minato lives alone because his parents are away for work. He is friendly with many of the girls that live in the same apartment as him and attends school together with them. However, his parents inform him one day that he will be transferring to another school. His quiet days soon gradually become quite rowdy as all the girls want to show their feelings for him when they realize that this is the last chance they will get. [From Hau~ Omochikaeri!]
