ALDN-270 Bride's Mother and My Father Akari Niimura

It's been about 4 years since my wife and I got married. This man is my biological father. My real mother passed away, and I now live with my parents and my wife. And the woman here is the wife's mother. This corresponds to the so-called [mother-in-law]. Sometimes my [mother-in-law] would stay at my house to see my wife, and we lived a peaceful life. But I wonder if it's possible...my father had such a relationship with my wife's mother.
