Xiah was recently on the talk show, SBS' Intimate Note (Video is here!) , where he was supposed to call a friend and solicit the words "You are my best friend." from him. Not surprisingly at all, Junsu called Super Junior's Eunhyuk, the two have been best friends since elementary school. The call did not go as smoothly as Junsu probably had hoped. Junsu asked Eunhyuk what relationship they have. After some embarrassed laughs and recounts of their friendship on Junsu's part, he was finally able to extract the admission that "We are best friends." from Eunhyuk.
