Earlier, we reported that Kim Yuna had praised f(x)'s Krystal for her stunning performance on ice. On the July 17th broadcast of SBS's 'Kim Yuna's Kiss & Cry', Krystal and her partner Lee Dong Hoon demonstrated�a circus-themed performance to The Eurythmics' "Sweet Dreams". The theme of the show was 'friends', so Krystal and her partner decided to cast Krystal's fellow f(x) members. Krystal's performance was full of difficult lifts, beginning with the mid-air swing lift. Following this difficult move was yet another, with the 'Tetris lift', in which Krystal moves into a handstand, holding onto her partner's skates. They continued with the 'necklace lift', where Krystal wraps her body around her partner's neck. Krystal revealed, "It isn't scary because I trust my partner." Judge Kim Yuna commented,

"The skating was very good, but I feel that it was lacking color. The lifts were a show of their own, and the skills demonstrated were enough for me to believe if someone said [Krystal] was an ice dancer."
