She was involved in a dispute with Korea Broadcasting System (KBS) for failing to show up to filming of the drama Myung Wol the Spy on 14 August 2011. Her agency cited conflicts with her PD over her working conditions, although it earlier explained that her absence was the result of poor health. It was revealed that she worked several extra hours and slept for only one to two hours for several weeks. She also received an injection for fatigue. She unexpectedly left South Korea to return to Los Angeles that day. At a meeting on the 15th, Kim agreed to return to filming on 16 August. She returned to Korea on the 18th bringing her mother back with her for support. She was reported to have given a press conference at the airport apologizing on her sudden absence citing difficulties and hardships she had. She also remarked that she firmly believes that what she did was right despite criticism from the public and other media sources that pointed out her unexpected sudden absence from shooting.
