The daughter-in-law and father-in-law seeking a godfather - Nanahara Sayo KSBJ-339

I lost my wife early and was left to raise my gambling-addicted son alone. However, my son married a young and beautiful woman. I couldn't help but look at her strangely; she was simply too alluring. One day, I discovered that my son and daughter-in-law had accumulated a large gambling debt and were planning to raise money through illicit means. So, I decided to put on a theatrical performance.
