It turns out that B2ST's Hyunseung made a cute mistake while covering Kikwang's part during the 'KBS New York Korea Festival' concert. During�the concert, which was aired through KBS on October 22nd, Hyunseung covered for Kikwang who couldn't attend the event due to scheduling conflicts. Unfortunately, while�singing their hit song "Beautiful", Hyunseung accidentally switched up the original lyrics, "listen to my heart", to "tell me". Instead of getting flustered, Hyunseung carried on so naturally that even KBS didn't realize that he had made a mistake. As such, they then made the mistake of airing the show with "Tell me" in place of "Listen to my heart" for the lyric captions at the bottom of the screen. Netizens commented, "He was so professional! I didn't realize he had made a mistake!", "The caption mistake is even funnier", and "He must have gotten momentarily confused since it isn't his part." Source + Photo: fnnews via Naver
