During the latest filming of QTV's 'Handsome Boy Communication', Crayon Pop shared their honest thoughts on the unique concept for "Bar Bar Bar" and their previous songs.

They explained, "Our agency is a new business, and it was our CEO's first experience in the entertainment world. We prepared our concept specifically to set us apart. With our 1st album, there wasn't much different from us and other girl groups."

Crayon Pop also told the story of how they came to wear helmets, saying, "In the end, we wore training gear and helmets. To be honest, when people stared at us strangely or when we went to broadcast stations, we were embarrassed. It was an idea that ChoA came up with. At first, the CEO was doubtful, but then we went to buy helmets. We tried out motorcycle helmets first before our current scooter helmets."
