On the recent episode of SBS’s “Kiss & Cry“, f(x)’s Krystal, together with her partner Lee Dong Hun gave once again a spectacular performance, this time based on an OST track from the hit movie, “Pirates of the Caribbean“.

However, just right after the production, Kyrstal collapsed out of exhaustion. She was immediately 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 the 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 further said, “I will eat lots, work hard and show a better image.”

The ‘Lifting Couple’ got over 9 points from all four judges, earning a total score of 36.6 points.
