He said regarding her, "When I first saw her, Moon Chae Won's voice was very, very quiet. She had a vocal tone [that makes you think] she would listen closely to you as if she were listening to the counseling of a neurologist.  That was charming.  That was charming for me."

However, apart from the first impression, he continued, "But she comes out differently when she's acting in 'Goodbye Mr. Black.'  Those aspects were fun for me."
