Married for 5 years, no children. Sometimes, we have what you might call a marital quarrel. The other day, we had a fight over something trivial, and in the heat of the moment, my wife got so angry that she ran out of the house. Well, this was a common occurrence, so I just left her be, thinking she would come back eventually. But that night, I got a call from Takashi, a single man who lives in the same city, saying, "Your wife has come to live with you."
