How could a 19-year-old woman achieve perfection while bearing an entire nation’s hopes and the baggage of its past, while 50 million South Koreans stood on her shoulders as she tried to stay upright while doing triple jumps on a slippery surface with knife-thin blades?

That is what Yuna Kim did 10 years ago on this date, lifting spirits in her homeland and elevating herself into a singular place in Olympic history by winning the women’s figure skating title at the 2010 Winter Games.

How? Even Kim still marvels over that, as she said in an email interview done this month through her management company. Even now, the moment confounds her, brings back the nervousness she had in Vancouver and, as it did then, makes her teary-eyed because she feels overwhelmed.

“I always wonder how I did it, and every time I watch, it doesn’t seem real,” she said.

She had not only won South Korea’s first Olympic figure skating gold medal but had beaten an exceptionally talented Japanese rival for it, a fact of no small consequence given the complicated history of relations between Japan and South Korea for five centuries. Sports competitions between the two countries had always been freighted with nationalistic implications.
