Already on their third performance into promotions, the five fabulous ladies of f(x) are showing no signs of wavering. With every passing performance, the girls just keep coming back fiercer and with even more charisma than before! Though some of the girls got a little too into the shirt lifting portions during the performance yesterday, it seems that they've taken it down a notch for the day. However, the fierceness is still very much alive in their performance. With spot-on dance moves and killer vocals, most notably from Luna, these girls continue to impress!
