Early life.

Career.
Choi was scouted by a talent agent from SM Entertainment when he was 16 as he was waiting for friends in front of his high school. The agent recommended him to audition for the company's "Starlight Casting System". He auditioned without his parent's approval; his parents were notified only after he passed the auditions. Although his parents allowed him to sign a contract with SM Entertainment, they did not give him any help because they wanted him to take responsibility for his actions.
He later moved into dormitories with fellow trainees and was trained in areas of singing, acting, dancing as well as languages. He was featured in a music video of The Grace's Dana whilst he was being trained as a solo singer in 2003. A year after, Choi made a brief appearance in family drama, "Precious Family" and again in 2005 in the KBS romance comedy drama "Eighteen, Twenty-Nine" as young Kang Bong-man, while in 2006 he played the supporting role of Park Sang-woo in romance melodrama "Spring Waltz".
Debut with Super Junior and Super Junior-M.
Not long after Choi's first television appearance, SM Entertainment released an announcement that he would debut as one of the twelve members in a boy band. A few months before the debut of Super Junior 05, Choi made his first media appearance with bandmate Han Geng as one of the runway models in a fashion show by Bum Suk.
Choi debuted as part of 12-member rotational project group "Super Junior 05" on 6 November 2005 on SBS' music program "Popular Songs", performing their first single, "Twins (Knock Out)". Their debut album "Twins" was released a month later on 5 December 2005 and debuted at number three on the monthly MIAK K-pop album charts.
In March 2006, SM Entertainment began to recruit new members for the next Super Junior generation. However, plans changed and the company declared a halt in forming future Super Junior generations. Following the addition of thirteenth member Kyuhyun, the group dropped the suffix "05" and became officially credited as Super Junior. The re-polished group's first CD single "U" was released on 7 June 2006, which was their most successful single until the release of "Sorry, Sorry" in March 2009, which helped them achieve global success. 
In April 2008, Choi was put into seven-member sub-group Super Junior-M, a Mandopop subgroup of Super Junior for the Chinese music industry. They debuted in China at the 8th Annual Music Chart Awards, simultaneously with the release of their first music video, "U" on 8 April 2008. This was followed by the release of the debut Chinese-language studio album, "Me" in selected provinces in China on 23 April and 2 May in Taiwan.

Controversies.
On 30 September 2017, an untied French bulldog owned by Choi's family bit their neighbor, 53-year-old businesswoman Kim who ran Hanilkwan, an upscale Korean cuisine restaurant. This resulted in the death of the victim six days after the incident. The cause was identified as sepsis, brought on by the bite. Choi and his father separately wrote letters of apology on their Instagram accounts on 21 October 2017. Although a family member of the deceased told media that the family were not willing to take any legal action, the Choi family received severe backlash from the public for not taking any precautionary measures with their dog.
Philanthropy.
Choi has joined many UNICEF campaigns since 2010. He was appointed as the special representative of the South Korea committee for UNICEF on 12 November 2015.
Upon his release from the military, Choi confirmed to volunteer for a UNICEF campaign in Vietnam from 21 to 25 August 2017, alongside fellow labelmate Jaemin of NCT Dream.
