yuria, who was spending a peaceful newlywed life with her beloved husband, was only thinking about a happy future. one day, she ends up sheltering "koji" (her husband's father, a useless man who was fired from his company because of sexual harassment and a habit of dating services). yuria naturally disliked koji, but her husband said, "he's my only relative, so i can't leave him," and she had no choice but to live with him... 13 days of hell begin, where her heart and body are violated by that man she hates so much...
