Choi Sung-bong

After passing elementary school and middle school through qualification examinations,[5] Choi graduated from Dae-Jeon Art High School, and went on to study at the Department of Cultural Art Management at Kyung-Hee Cyber University.[6][7]

During his troubled youth, Choi claimed he hid at a night school at age 14 to escape area gang members. He learned how to read and write and applied for qualification examinations to pass elementary and middle school and enter high school. With hopes of learning music and spending his school years with friends, he entered Dae-Jeon Art High School. To earn school tuition fee and private lesson fees, he worked at a delivery service, but suffered an injury while working. Choi thought about dropping out of high school, and his music teacher testified that he was often absent because of the underprivileged surroundings. He gained admission to Hanyang University, but due to financial difficulties, was unable to pursue undergraduate education. Instead, he spent his days working as a day laborer.

On 6 June 2011, Choi's performance of Ennio Morricone's "Nella Fantasia" on Korea's Got Talent was received positively. He introduced himself as a manual laborer who had made a living selling gum and energy drinks for ten years. All three judges, Kolleen Park, Jang Jin and Song Yun-ah, were impressed enough with his vocal talent that Choi was advanced to the finals of the competition, finishing second by only 280 votes.

Choi's performance clip was posted to YouTube and received praise from pop stars Justin Bieber, BoA, Jung-Hwa Um, several hundred thousand fans on Facebook, as well as political figures such as South Korea's former president Lee Myung-bak.. One version with English subtitles[8] had triggered international press interest, with claims that Choi was "the next Susan Boyle".[9][10] As of September 2020 the video has 175,078,474 views.

On 4 June 2011, after his first appearance on the show, some people accused him of concealing the fact that he had graduated from art high school although he was rarely able to attend classes due to his financial situation and was said to have received his diploma out of pity.[11]

The KGT production team explained that "It was cut from the film during editing. He stated that he'd graduated from art high school at the second local tryout, and the judges, crews and hundreds of audience members heard that." KGT later broadcast the re-edited version including the statement.

After his appearance on KGT, other major entertainment companies persuaded Choi to sign contracts with them. Ultimately, he signed with Sony Music Korea Inc. but cancelled the contract in December 2011. Until his death, he was signed with Bongbong Company.[12]

Choi claimed in January 2021 that he was suffering from cancer and raising funds to support his latest album. On 29 October 2021, Choi admitted to faking his cancer illness. In an apology released to Korean media, Choi stated, "I am not currently suffering from cancer and I admit that I am not suffering from colon, prostate, thyroid, lungs, brain, and heart cancer."[13]

Choi died by suicide on 20 June 2023, after having left a suicide note on his online channel, which has since been taken down. He was 33.[14][15]

CNN commented that "His powerful baritone voice sounds as if it belongs to a man twice his age and build."[16]

Choi was an honorary ambassador of ChildFund Korea, the organization which helped him to improve his own life. He said that he won't just tell the children to "have hope and dream", but he wants to help them practically by giving them a chance of a better life. He was also an honorary ambassador of the Chang Dong Social Welfare Center.

Choi had said, "People who suffer have feelings that can't be explained by words. I hope my performances provide some consolation and an uplifting feeling to those in need." He performed for non privileged people, including single mothers, youths in juvenile custody, and hospice centers.
