Five years after reaching South Korea, defector Kim Yoon-hui, 27, looks totally up-to-date as she walks between classes on the campus of Hanyang University, where she's majoring in Chinese. Appearances are deceiving. Knowing almost nothing about the outside world until she escaped North Korea in 2001, Kim says that she often feels awkward and ill informed in her new world. "At parties people talk about movie stars and music and politics, and I usually don't know what they're talking about," she admits. "I smile and pretend I know everything, but I come home exhausted."
