With Narsha taking leave for a week for her radio show, Raise The Volume, guest DJs were recruited to fill her vacancy and among them was idol girl group, f(x). The girls completed their guest DJ duties successfully recently and took photos to mark the occasion. In the photos, the f(x) members posed with a victory sign and smiled lovingly. But Sulli was the odd one out as she posed with her chin resting on her clenched fists. Netizens commented, "They all looked so lovely with the close-ups," etc.
