And your point is? Yuna is considered a star in the S. Korea, but it's really no different from how US media obsesses over Lindsay Vonn or maybe Japan over Mao Asada.An informative article on the cultural phenomenon that is Yu Na Kim in her home country:
For instance, did you know that stock trading in South Korea took a dip during the few minutes or so that Yu Na Kim was skating her short program? Apparently all the stockbrokers abandoned their money-grubbing to watch her skate. You can also see a picture of a massive crowd that gathered to watch her skate celebrates after she wins.
Edited to add: This article from Deutsche Presse-Agentur confirms that trading was halved during Yu Na's free skate as well.
