So who exactly is the person or persons responsible for bringing the usually composed sexy diva Lee Hyori to tears? Hyori is currently a judge for the show Superstar K, and it was on the 25th of August that Hyori's tears began to pour from her pretty little eyes. On that day, a blind contestant by the name of Kim Kook Hwan expressed his sincere thanks to his group mates prior to their performance. "First off, I want to thank my team members. As everyone can see, I can't see things that are in front of my eyes. Which is why my team members could not choose a dance song, this is a really competitive stage and just because of me, they made a major sacrifice. This wasn't an easy situation, but just for me, they chose a ballad. I want to take this opportunity to thank my team members for being so considerate to let me accomplish this mission, they have always been by my side." With that, everyone was immediately swept with emotion, which carried on even further as the group performed 8eight's "Without a Heart" in perfect harmony. During the middle of their beautiful performance, Hyori began to cry. She later expressed, "Using a song to touch people isn't an easy thing. 8Eight's 'Without a Heart' is such a beautiful song and today I felt it again." It's good to see people valuing friendship and making such a huge sacrifice.
