To make matters worse, he finds out that his eldest son, Jotaro, had been secretly having an affair with his own secretary, Saeko Godai, and it seems that she is also expecting a little ‘Burden of Love.’ Also, the Araki family’s young daughter, Sakura, has become pregnant with her fiancé before their upcoming marriage, and even the retired patron of the family, Jozo, 2 presents yet another possibility of a pregnancy with his much younger mistress.
