Actress Kim Sun Young from 'Reply 1988' revealed that she knows nothing about the entertainment world.

The actress shared, "I didn't know Hyeri before 'Reply 1988,' so I just thought that she was a very good rookie actor. So I told her, 'You'll be famous soon,' and she replied jokingly, 'I'm already famous.'"

She also said, "I once noticed Yoo Yun Suk paying a lot of tax, so I asked, 'Why do you have so much tax? Are you a star or something?' And it turned out, he really was. Once time I asked Nam Sang Mi -- who debuted 13 years ago -- 'Is your dream to become an actor?'"�

Kim Sun Young stated that nowadays, she looks up entertainment news to avoid making awkward mistakes. She said, "I know who Kim Kook Jin is dating, and I also watched Kyuhyun's new MV."�
