The government wasn't very impressed when Hyun's story was released in 1978. As his Wikipedia page relates,
The story was the first ever written about the Jeju massacre, and shortly after it was released in 1978 in a collection of stories, Hyun was arrested and tortured for three days. The government claimed that this was because he had been at a protest, but as he was released he was warned against ever writing about the massacre again, which made the real reason for his arrest apparent.For those interested in reading the story, there is a new translation available.
On the same topic, the film Jiseul, which is about the Jeju massacre, will be released in Seoul today (after being released three weeks ago in Jeju). The film won the World Cinema Dramatic Grand Jury Prize at January’s Sundance Film Festival last year, though it didn't appeal to everyone. The Korea Times took a lengthy look at the film and its director, Jeju native O Muel, earlier this week.
On a related topic (especially thinking of Hyun Ki-young's arrest and torture), today the Constitutional Court ruled that emergency decrees No. 1, 2, and 9, created to defend Park Chung-hee's 1972 Yushin Constitution, were unconstitutional. I enjoyed Stars and Stripes' contemporary description of emergency measure 9 as the law which makes it illegal to criticize the law which makes it illegal to criticize the Yushin Constitution.
