On the May 26 broadcast of MBC FM4U's 'Park Kyung Rim's 2 O'Clock Date,' Luna dished on her experienced on 'Mask King' and also revealed Lee Soo Man's reaction to her appearance on the show!  

Luna confessed that her alias as 'Gold Lacquer' was exposed due to her distinctive nails, which made her easily identifiable. The singer also revealed, "After 'Mask King,' I came to love myself more and gained confidence [in my singing ability]." 

When Park Kyung Rim asked whether there was a possibility of her going solo, the singer replied, "Truthfully, around the same time I removed my mask, my solo digital single was released. Even up to that day, SM hadn't known that I could sing with such emotion. They showed positive interest in me and said let's keep on going in this direction." 

Luna also noted that she received a congratulatory message from Lee Soo Man, who apparently encouraged her by saying that he will continue to watch her progress as a singer.
