I was born in Korea, and my family came over to America when I was 10. I’m the middle child of three girls, and my parents moved so we would experience a different life. They did it for our education and to give us more of a chance than they had. We moved to Staten Island, and I went to the High School of Performing Arts in New York City. My parents didn’t agree with me when I told them I wanted to be an actress. My father suggested I try premed(医学预科). But after they saw me in plays they were really proud.

I graduated from Boston University and was doing theater in New York when I got cast in a Korean miniseries(电视连续剧). We started shooting the show in New York, and then went to Korea to finish it up. They said I would be there for three weeks, but it ended up being two months. The miniseries took off, and overnight, I became recognizable. It was sort of like Lost. It blew up. Then amazing projects were offered to me. I kept thinking, “ I’ll do one more and then go back to the US.” I ended up staying for seven years.

Some people described me as the Julia Roberts of Korea, which is a bad comparison because she’s the queen of romantic comedy. I became famous in Korea for a dramatic role in a film called Shiri. I played a “La Femme Nikita” type of role. I was the girl with gun—all action.
