The hero of the story, Mr. and Mrs. Fifty Lan, is a typical sister-in-law relationship. Both of them have suitable jobs, bought houses and are ready to have children. Unfortunately, I was not pregnant after one year, so I especially envied my neighbors. The whole drama embodies the traditional Japanese concept of attaching importance to family, having more children and encouraging fertility. It also encourages people with different marriage relationships to get along, which can reflect some social phenomena in contemporary Japan.
