It's been about 4 years since my wife and I got married.This man is my real father.His real mother passed away and he lives with us, his wife and his parents.And the woman here is the wife's mother.It corresponds to the so-called [mother-in-law].Occasionally, [mother-in-law] would stay at my house to see my wife's face, and I was spending my days living peacefully.But I don't know what to do... My father had such a relationship with my wife's mother... At that time, I stood there speechless...
