She said, "After featuring in Epik High's song, I received a solo version as a present from Tablo," talking about "Umbrella."  When she was asked which song she wanted to sing again, she chose "Picnic," which she had sung with So Ji Sub.

MC Yoo Hee Yeol said, "Seeing So Ji Sub after working with Yoo Hee Yeol, Kim Bum Soo, and Tablo after all that time, you would say that," making everyone laugh with his self-diss.
