The father-in-law of the eldest son-in-law's family is a retired reporter, and he still retains the identity of an intellectual. Decent and sensible, but unfortunately he is picky about his wife. The relationship between the two is at a standstill. After the father-in-law's friend passed away, he went back to the study and cried alone, but the wife outside often burst into hearty laughter.
