As hard as it is to believe now,�NS Yoon Ji revealed that she was actually a loner during her school days because of a language barrier issue. She stated during a recording of "100%",�"I immigrated to America during the 4th grade, and I didn't know English at the time, so I wasn't able to communicate, and I became a loner." Yoon Ji went on to say, "With the principal's help, I adjusted to school life and I became who I am today." This episode will air on KBS 2TV on December 11th at 5:15 PM KST. Source + Photo: nate
