I wonder if that is the same group, Super Junior, that Heechul comes from... (who is on all the game/variety shows) / such as Men on A mission, or Knowing bros., depending on the translation - i think. . . but that one's on Netflix with like a million seasons to it. So, it's the one I've seen most! And anytime one of the girl groups comes on there, he always seems to have a real tight relationship with one or some of them (the members of the band). Like even the younger ones seem to look up to him a lot. So, he must be a great mentor, and you can tell his background, because anytime they bust into dance --& he joins in; he is WAY Too Good~*>
