An interesting scene featuring f(x)'s Krystal that occurred during the filming of SBS's "Kim Yuna's Kiss & Cry" was revealed. According to the May 27th reports from SBS, Krystal screamed out loud, "Aaakk~~" during the filming for a performance on the show, which took place at the SBS Production Center in Ilsan on May 24th. Her scream came out naturally as the performance required her male partner to lift and spin her around. Krystal explained, "I couldn't help but scream because it was so scary." Krystal's coach added, "For someone to scream like that during a performance is a very rare occurrence. There's cases when couples quietly count, '1-2...1-2' to match each other, but this is the first time I witnessed something like Krystal's scream." On this day, Krystal safely finished her prepared routine, receiving a big round of applause from the audience. [gallery] Source: Asia Today via Nate Tip: VSolit
