Luna appeared on SBS radio 'Cultwo Show' on February 9 to promote her new movie, 'The Lightening Man's Secret.'

On this day, she was asked, "What kind of movie do you want to film next?" and she replied, "I want to film a melodrama rather than a romantic comedy."

The DJ followed up with, "With which actor would you like to film a melodrama?" and she first mentioned her co-star Jung Hyun Jin, then stated, "So Ji Sub?"  Good choice!

Would you like to see them acting together?
