It was Lee Sang-hwa, one of Korea's leading hopes in Sochi, that broke Korea's medal duck at this year's Olympics.
Skating in the women's 500-meter event, Lee clocked a combined 74.7-0 seconds with her two races, setting a new Olympic record in the process.
She beat second-placed Russian Olga Fatkulina by 0.3-6 seconds.
Setting another Olympic record with her time of 37.2-8 seconds in her second race, Lee is now one of just three skaters to win the two consecutive gold medals in the women's 500-meter race, along with Bonnie Blair of the U.S. and Catriona Le May Doan of Canada.
She is also the first Asian to win two straight gold medals in the event.
It's not over yet, either.
Lee will also go for gold in the 1000-meters on Thursday evening, Korea time.
Lee started her career when she was a child, changing to speed skating from short track in the fourth grade.
She later joined the national team at the age of 15.
Known for her strong will to win, Lee did not skip a day of school, while practicing on the ice.
