According to a national census, the number of unmarried women between the age of 30 to 40 has been increasing and is now at the highest. Compared to 10 years ago, the rate of unmarried women have increased by 6.7% and 8.5% for woman in their early 30’s and late 30’s, respectively. Why are they not getting married? The women appearing in this drama are unmarried for various reasons including, they have high expectations, are not able to be themselves in front of men, become attracted to losers, think being single is much more easier, or they think men are unreliable. They’re almost about to lose all hope, however, it’s not that they don’t want to get married, it’s just... things just don’t work out, they don’t know if they’re getting married for themselves or to please others, or they question whether there really is a reason to get married. This drama will realistically portray the trials and tribulations of love, friendship, and work of these women. ~ Fuji TV
