In South Korea, a young female celebrity  in her late teens to early twenties who is representative of her time is often called the “National Little Sister” (국민 여동생). A National Little Sister must also be cute, bright, and innocent—as soon as she gets a glitch on her innocent image, her title as National Little Sister is over. I know, what a cruel world! Some recent National Little Sisters include actress Moon Geun Young (in the past), IU, and the rising rhythmic gymnast, Son Yeon Jae. Did we miss anyone? Who's your favorite National Little Sister?
