Erina has grown increasingly distant from her husband, who does nothing but work, so she confides in the father-in-law who lives with them about their troubled marriage.

But the moment they are alone, his gentle facade disappears and he forcibly rapes her. Her father-in-law had been waiting for his chance all along, lusting after her beautiful, alluring body.
