Unpleasant compliments

Late last year, a documentary program was broadcast on TV about a couple who left their elementary school-aged child in an Asian country and came to Japan to work as migrant workers.
While the words "tourists visiting Japan" and "inbound" are no longer heard due to the spread of infectious diseases worldwide, there are foreigners who cannot return to their home countries and are working in an environment that can never be said to be favorable.
Japan has a magical power to tear families apart.
Safe and clean cities, healthy and beautiful Japanese food, hospitality and hospitality.
The list of Japan's charms is endless.
However, these are positive aspects that only those in a position to enjoy them can see, and different people see them differently.
I can't help but hope that the famous song "Cotton Handkerchief" of yesteryear will not suit the relationship between this father and son, regardless of the relationship between a young bachelor who has come to Japan to work and his wife who has left him back in his hometown.
