G.NA's agency Cube Entertainment tweeted on the 17th, "Wow the two hot girls who are shaking up the music scene! The two beauties who exchanged their albums in the waiting room at #MusicCore, the mahd-unni [oldest] and maknae from the legendary group from long ago meeting in the sweet and eye-catching two-shot! #GNA × #Hyosung #Secret", along with the backstage photo.

G.NA and Hyosung have both come a long way from training together as members of the group 5Girls and are now achieving success as solo artists. The two friends have become friendly rivals with their glamorous figures and album releases on the same day (May 12) with their title tracks by Duble Sidekick. But their friendship goes a long way as shown in the sweet shot above!
