Their irresponsible father left them alone in Tokyo while he moved out of the country, which needless to say creates an interesting atmosphere at home. Though Masuto has strong feelings for his girlfriend, he also feels attracted to his step sister; and now, Masuto must discover his true feelings and make a choice – or start two-timing on both of them!
