On March 15 episode of KBS Cool FM's radio show 'Park Myung-soo's Radio Show', Koo Hye Sun made a guest appearance.

Park Myung-soo said, "You direct movies, write books, exhibit your artworks besides acting and singing. It must cost you a lot of money to do all those things. You lived in a huge house as well."
Koo Hye Sun laughingly answered, "Well, yes, I used to live in a big house, but that was when I had a family. I live in a one-bedroom house by myself now."
She continued, "As for money, if I work hard for a month, I can do whatever I want for a year. For the last 10 years though, I've been doing what I wanted to do pretty much with the money I made with 'Boys over Flowers'."

Koo Hye Sun responded, "It was a stroke of luck that I got to join 'Boys over Flowers'. It was a big one as well. I would say that it was something like winning a lottery."
The actress said, "When I sat down for a meeting with the production team of 'Boys over Flowers' for the first time, I actually insisted on making my character 'Geum Jan-di' the way I wanted."
She went on, "I didn't really like the way she behaved at certain moments. I didn't think she should behave like that just because she was a woman."
She added, "At that time, the writer sat me down and calmly explained to me that was simply what 'Geum Jan-di' was like. I think I was too young at that time."
