It's been about 4 years since my wife and I got married. This man is my biological father. His biological mother passed away and he now lives with me, 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. However, it must have happened...my father had such a relationship with his wife's mother...At that time, I stood there without making a sound...
