AOA appeared on 'Cultwo Show' on January 12!
DJ Jung Chan Woo asked them, "Wasn't it hard [learning] the choreographies when you have two title tracks? Which member was the slowest to learn them?" and the AOA members first said, "Chanmi is the fastest."
The DJ persisted with, "There should be one member who reacts the slowest. Tell us honestly." ChoA said, "The younger you are, the faster you are. The older you are, the slower you are. Jimin and I are on the slow side," making the others laugh.
