[4] Yun's sole translation into English is Danny the story of a too-human-like robot.
Yun takes postmodern trends, in this case the weakening of family bonds, increased mechanization, and the alarming Korean susceptibility to large-level loss of life during catastrophe and blends them together into a charming, and ultimately sad, story of new and unlikely social bonds being restored – in this case between a worn out grandmother and a childcare robot named Danny.
Danny is Yun's only translated book so far, but as “Her writing ([is] known for going beyond the boundaries of dreams and reality” (Naver Encyclopedia) including topics controversial in Korea such as homosexual love.
