HyunA has unveiled a mood poster for her comeback with 'Nabillera'. 

The mood poster features a shot of HyunA facing away from the camera, a pair of flamboyant wings on her back. A segment of lyrics reads, "I fly like a butterfly and land on you. Leave traces of me everywhere. Let me turn you on right."

More details on HyunA's 'Nabillera' will be out soon, before the singer's full comeback on July 20 at 6 PM KST.
