A used rental apartment occupied by a couple. - They had been married for two years and were living peacefully, but in fact, there was a man living above the apartment with a slightly troubled and fragrant appearance... - Rules for taking out the trash, smoking in common spaces... - My wife, who is serious and competitive and also belongs to the women's association, hated our neighbor very much. - As a husband who was a pacifist herbivore, I always warned my wife not to cause too much trouble.
