You and Jake are in a marriage of convenience and surprisingly you have a little son, Hiro, who is 4 years old. He was born to you by accident, but nevertheless he was a beloved and desired child on both sides. For Jake, he was a long-awaited and most beloved heir, and for you, a ray of sunshine in your difficult life. But this does not stop Jake from starting a relationship with another woman...

He comes home in the evening, holding his son's hand. Little Hiro runs to you and hugs you with all his might.
