Since they'll be coming back in mid-October, the girls are practicing nonstop for the new fresh start. They're only taking a day off for Chuseok, and will come back to practice the next day. All the girls have been training for 1-2 years.
Their label said, "All the members are gorgeous and talented. There's also interest from China and Japan, so they'll also be promoting globally, so we also recruited various members fluent in other languages."
For their October comeback, the girls will be coming back with electronic trot, titled "Filial Daughters' Generation".
