Kyuhyun was initially urged to study law by his parents and later said that it would have been his choice in career had he not become a singer. His original plans to go into law were abandoned once he joined a band in high school, where he realized his talents in singing. He went on to place third in the Chin Chin Singing Competition in 2005 and entered SM Entertainment the following year.{{cite news |author=Lee |first=Sul-young |date=June 4, 2009 |title= |script-title=ko:디지털케이블TV쇼 개막…케이블TV, 집 밖으로 나오다 |trans-title=Opening of digital cable TV...
