South Korean singer, stage actor, and television personality Cho Kyuhyun delivers heartfelt, multilingual ballads as a solo artist, but he is best known for his role as a member of K-pop group . Starting in the mid-2000s, Kyuhyun and his bandmates were Korean chart kings for a decade, notching seven number one albums in their home country and branching out into Asia and the U.S. The first  member to go solo, he debuted in 2014 with At Gwanghwamun.
