On the January 18 airing of Mnet's 'I Can See Your Voice 6,' Lee Sun Bin and Hwang Chi Yeol joined as the guest singers. The two walked into the studio with all the guests singing Queen's "We Are the Champions."
Lee Sun Bin expressed nervousness, saying, "I'm so nervous. I think I'm more nervous than the time I was a mystery singer."
MC Kim Jong Kook, who is on 'Running Man' with his close friend Lee Kwang Soo, stated, "Don't be nervous. I received a message early in the morning (from Kwang Soo), telling me to take good care of you." To this, Lee Sun Bin shyly laughed.
