Heo Young Saeng said, "Hyun Joong is active in the military so it's hard to reach him. Jung Min is a public service worker so we keep in touch regularly. He told us, 'I hope you guys do well.' I don't know if he was joking but he said, 'I will have the choreography all memorized. I'll make it so that I'm ready to commit myself.' He said all that in a joking manner."

Kim Kyu Jong chimed in, "Hyun Joong's mother heard about our promotions and she was happy and said she'll support us. I think she is a big strength to us."
