On July 5 KST, Cube Entertainment released two individual images of HyunA, and another with HyunA and Hui. As the first batch of concept photos, these images hint a nice mix of vintage and avant-garde, simulating their album title 'REtro Futurism'. HyunA and Hui look ravishing together in formal retro outfits, and HyunA dons unique designer pieces with floral props in her individual images. On the bottom for each image, the words "COMING SOON :)" indicate Triple H's long-awaited comeback.
