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.
