Since you are in Korea, today, I want to help you clarifying the President Park's issue in Korea.
but it can be not accurate. I will tell you the story based on some articles I read.
Problem started when the fact that Park's text of speech has been corrected by Choi was revealed to public. Also national secret documents were found in just civilian's tablet PC which owned by Choi. She denied it, but everybody knows it is hers. The problem is getting worse as people do investigation. Choi did not just gave correction in text, but also she involved in country's planning. for example, celebrations, development planning. etc. the killing point is she is just a 'citizen' not politician.
