Attention Please: It's a BIG HIT in Korea!

This sitcom is currently being shown on Korean television (M-F from 1730-1820 KST. I have no idea why it's such a big hit -- perhaps it strikes a chord with many young females who are short on domestic job opportunities but long on aspirations for a glamourous career that offers a chance to travel around the world and prestige. Besides Korea, are there any other places where this series has struck a chord or become popular as of late? If so, why do you think it is?
