The concept of the photoshoot was 'Flowers that bloom in December'. During their interview, the ASTRO members named the manliest members! Jinjin answered, "Cha Eun Woo and Moonbin have the manliest personalities. They're both blood type B's, but Eun Woo has a more detail-oriented personality while Moonbin has a fiery side." 

Cha Eun Woo said about an acting role he wants to try, "I want to try a prep school genre while I'm still young. I've been portrayed with a well-mannered image up until now, but I want to try a more rebellious student." The idol also shared, "I want to be a cool and respectable person both on the outside and inside."

Finally, Moonbin coined his charm points as his "friendly aura off stage, and lean muscles." Check out ASTRO's pictorial below!
