Takashi is Satoshi's jealous little brother, living in the shadow of his older brother's success. But what ticks him off most of all is that his older brother stole the love of his life, Miwa, and married her.

One of Takashi's college professors, however, takes Takashi under her wing and teaches him how to be a real lady-killer. Takashi seduces his brother's wife, Miwa, as well as her younger sister.
