Super Junior Kim Heechul drummer on supershow

I'm talking about his injuries back in 2006 if I'm not mistaken. He almost crashed his whole left leg, and now got a metal rod installed in his leg. That's why he always has a small part only in every song, he didn't want to burden the group's image not being able to follow the group's difficult choreography. Since he couldn't dance well, that's why he acts does variety shows as another way to promote his group. The fact that he became an expert on the girl group's dance may also be due to this reason, which is quite sad when we think back. He tried very hard, but his smile often makes us forget his struggle.
