On September 29th, f(x)'s Victoria updated her Me2day with a group photo of the girls in Beijing sans Krystal. She wrote, "f(x) performed at the main stadium for the Beijing Olympics.� Krystal wasn't here.� We'll have fun here secretly before going back." Posing extravagantly with the stadium as their backdrop, Amber, Sulli, Victoria, and Luna can be seen throwing their arms up at the sky and showing off their slender bodies.� Krystal is probably missing due to her commitments to her new sitcom series, 'High Kick 3'. Netizens commented, "So pretty", "They all look amazing", "Is Krystal on another schedule?", and "Glad you're having fun in China." Source + Photos: Star News via Naver
