On this week's episode of SBS's "Kiss & Cry", f(x)'s Krystal and her partner, Lee Dong Hun, gave another beautiful performance based on an OST track from the hit movie, "Pirates of the Caribbean". To match their "Pirates of the Caribbean" concept, Krystal and Lee Dong Hun transformed into Elizabeth Swann and Jack Sparrow respectively. The couple lived up to their 'Lifting Couple' label as they showcased elegant movements with their trademark lifts, and were able to complete their climatic performance flawlessly. However, Krystal felt really exhausted and collapsed on the ice right after they concluded their performance. As a result, she was taken backstage to rest as a precaution while Lee Dong Hun stood in front of the judging panel by himself. Kim Yuna praised, "You always display head-spinning, awesome performances. I really enjoyed watching your performance today." Dong Hun replied, "I made a mistake in our first jump, and I think my partner lost her energy after that. I'm really sorry about it." During her interview after the performance, Krystal explained, "My condition wasn't well that day. I think everything just hit me all at once the moment we finished our stage. I had lost my appetite that day because of my bad condition. After our performance, I got really dizzy and couldn't stand back up." She added, "I will eat lots, work hard and show a better image." The "Lifting Couple" received over 9 points from all four judges, earning a total score of 36.6 points. Check out the performance down below! Source: OSEN via Nate, Star News via Nate
