?After School showed us just how hard they're practicing for their comeback!

The ladies released 3 'CCTV' videos featuring footage from their practice. The first one shows Nana and E-Young practicing their part of the dance. The two burst into giggles near the end after they mess up a little, and come down from the pole laughing brightly. The second one shows the girls eating and even sleeping near the pole stands. The 3rd shows the girls practicing - and Jooyeon's injury.

It looks like the ladies have really mastered pole dancing. Get ready for their comeback that's happening in less than 12 hours!
