Jun Ji-hyun
The series influenced Korean fashion; clothes, accessories and make-up products worn by Jun Ji-hyun saw an "unprecedented" surge in orders. The children's novel "The Miraculous Journey of Edward Tulane" by Kate DiCamillo, from which the male protagonist repeatedly quotes throughout the series, went to the top of the bestseller lists in major Korean bookshops. A luggage manufacturing company also saw increased sales in China after Kim Soo-hyun carried one of its backpacks. The drama also drew the international community to the Korean language; "시" (ssi), which Jun Ji-hyun adds after male protagonist's name, became the most-discussed word. Although the series was sold to China for per episode, its increased popularity led to a sharp rise in the price for the Chinese distribution rights of future Korean dramas.
