Having been cast for SBS's figure skating variety show, "Kim Yuna's Kiss & Cry", f(x)'s Krystal recently sat down for an interview with Asia Today and shared her experiences. "I fell so many times while rehearsing that I now have bruises on my knees.�It's still really fun and I'm totally charmed by the entire sport of figure-skating," she began. Moving onto the topic of working with Kim Yuna, she commented, "It was hard for me to regard her as anyone other than a world star, but she's extremely caring and tries to make everyone comfortable. She shares fun stories with me and we've gotten a lot closer by talking to each other more.�When would I ever get a chance to be close to a national hero like this?" When asked about how her first recording went, she replied, "Getting on the ice made me really nervous and I didn't have a lot of time so I wasn't able to rehearse as much.�The day before the recording, my choreography was changed up so I had to memorize it just a few hours before I was to go in.�I am a bit disappointed with that." Krystal also gave a thumbs up for the atmosphere on set.�"It's tiring physically, but spending time with the other nine members of the show is fun.�Park Jun Geum and Lee Ah Hyun are both older than I, but I don't feel the age difference at all and they treat me comfortably." "Kiss & Cry" will premiere on May 22nd. Source: Asia Today via Nate
