forgive me... My brother-in-law's greedy 4: Yamagishi no Otome

The divorce of Shigeki and his younger brother, Kaori's husband. Kaori had already been separated from the family, and he decided to ask about the situation with Shigeki's wife, Ayako, who was on the side of cutting off his divorce. Koori, who knew that Ayako had secretly engaged in an affair, did not know so and sympathized with Shigeki, who was taken for his own guilt.
