On MBC's Chuseok special of 'Duet Song Festival' on September 16, the singer appeared to partner up with Kim Jong Seo. In the interview with the production crew, she stated about Kim Jong Seo, "He's overflowing with charisma; is he not a rocker? At first, it was so hard. I worried about how to approach him, but actually, he took care of me better and was considerate."
She then added, "I'm feeling greatly burdened. That's why I prepared even more diligently. Han Dong Geun created the legend of 'yeok-joo-haeng (sudden reversal)' through 'Duet Song Festival,' and the members have great expectations for me. They're hoping that I will do well and do a 'yeok-joo-haeng.'"
