Choi made his debut as a television commercial model in 1987 and began his acting career three years later.
He rose to stardom in 1993 with the popular TV show Our Paradise, and his resemblance to his elder sister, popular actress Choi Jin-sil gave him a head start in his career, while his youthful image helped him gain recognition in various TV dramas, commercials and even films.
His first album Final Fantasy was a success, with the popular single "Forever" topping music charts.
In January 2010, Choi signed with a new agency, MCloud Entertainment, and announced plans on March 2 to resume activities in the first half of the year, but his approaching comeback added to his stress and he increasingly felt frustrated that he wasn't getting cast in any TV series.
[8][9] Choi's body was cremated and his ashes was buried next to his sister at the Kapsan Cemetery in Yangpyeong, Gyeonggi Province.
