BEAST's Lee Ki Kwang made his MC debut through the latest episode of KBS 2TV Win Win. In order to commemorate Ki Kwang's MC debut, the BEAST members all appeared as guests. Ki Kwang also expressed his dearest apologies to his fellow members. Before BEAST's debut, Ki Kwang first made his debut as a solo singer, AJ. Yoon Doo Joon, Yong Joon Hyung and Yang Yoseob actively participated as Ki Kwang's back dancers. One day, Yoon Doo Joon and Yong Joon Hyung were mute and didn't utter a word. Since they didn't have dorms to stay at, the two boys felt miserable, and they ended up crying on each other's shoulders. It wasn't till later that Ki Kwang realized his buddies were going through a difficult time. He expressed:

"After wrapping up my solo activities, I then became aware of their hardships. I've always felt sorry for later realizing what my hard working buddies were going though." "The members of BEAST are all of my good friends. Thank you guys."
