Choi is also a drummer, having performed with his senior labelmates, TRAX in September 2006 on SBS's music show Popular Songs due to the fact that their drummer, Rose, had left the band. He is skilled in Taekwondo and became the youngest in Korea holding the fourth rank in the black belt.
Pre-debut years
Choi was raised in a strict, Protestant family from Seoul, South Korea who owns one of Korea's biggest supermarket chains. After Choi's talents were scouted in the Starlight Casting System in 2003, his parents initially disapproved him to pursue in an entertainment career. After consideration, his parents allowed Choi to sign under the talent agency SM Entertainment. Choi said that although his father agreed Choi to sign the contract, he would not give any help to his son. Choi later moved into dormitories with fellow trainees and he was trained in areas of singing, acting, and dancing. He made his first appearance in a music video of The Grace's Dana when she was still a solo singer in 2003. A year after, Choi made a brief appearance in the short drama, Precious Family.
