His father was the former CEO of Boryung Medicine, a pharmaceutical company.[6] Choi graduated from Apgu Jeong High School in February 2006 and from Inha University in February 2012 alongside fellow member Kim Ryeowook.[7]

Career

[edit]

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 parents' approval; his parents were notified only after he passed the auditions.[8] 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.[9]

He was featured in a music video of The Grace's Dana whilst he was being trained as a solo singer in 2003.[10] A year after, Choi made a brief appearance in family drama Precious Family,[11] and again in 2005 in the KBS romance comedy drama Eighteen, Twenty-Nine as young Kang Bong-man,[12] while in 2006 he played the supporting role of Park Sang-woo in romance melodrama Spring Waltz.[13]

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.

Controversies

[edit]

Anti-LGBT

[edit]

In 2007, when being asked about male actors portraying sexually ambiguous roles as in The King and the Clown (2005), Choi said: "I will respectfully refuse any such offers. While I respect all genders, I do not wish to acknowledge homosexuals as I have been taught that God created Man and Woman with specific characteristics and duties. I realize that with globalization, there are many [entertainers] who do not share my views. There are those who are value-oriented and those who are success-oriented. However shouldn't an actor deliver an image to his audience through roles he chooses to portray, based on his beliefs in life?"[69][70]

On September 11, 2015, Choi retweeted theologian John Piper who stated "Obergefell is not constitutional; so-called same-sex marriage does not exist." Choi also shared Piper's link to an article in support of Kim Davis, as well as two Biblical passages, confirming he remained against gay marriage. The next day he removed the retweets and posted an apology in both Korean and English. The English version went, "I apologize for my inconsiderate choice to retweet Rev. Piper's tweet. Reason I echoed Rev. Piper's thoughts was because I wished to voice a plurality of opinions. However, now I realize that my comments were hurtful to those whom I hold dearest: my fans, and their friends and families. I am truly sorry. My judgment was insensitive, thoughtless, and ill-conceived. I will do my best to learn from my mistakes and reflect on my faith. I thank everyone for their support and understanding." He later deleted the apology.[71][72]

In April 2023, Choi has been accused of transphobia over a meme he posted on Bubble, a private online discussion platform. The controversial meme shows a scene from the movie Titanic (1997) in which actor Billy Zane's character Caledon Hockley is trying to be rescued but is told "women and children first." Zane's character then claims: "I'm trans." Choi wrote "It's funny kekekekeke" along with the image.[73][74][75]

Deadly dog bite

[edit]

On September 30, 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 October 21, 2017.[76] 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.[77]

Tribute to Charlie Kirk

[edit]

On September 11, 2025, following the death of U.S. political influencer and Trump ally Charlie Kirk, Choi posted an image on Instagram with the caption "REST IN PEACE CHARLIE KIRK, Charlie Kirk, rest in peace." The photo featured Kirk's face alongside a cross illustration and was set to the song "Rescue" by American CCM artist Lauren Daigle. Choi also shared a second photo of Kirk with his family, accompanied by the Bible verse "Well done, good and faithful servant." Both posts were deleted after drawing criticism from K-pop fans, most of whom cited Kirk's far-right positions, including his support for gun rights, opposition to abortion, and remarks described as racist and anti-LGBT.[78][79]

On September 12, 2025, Choi addressed the controversy on the fan platform Bubble. He wrote that there had been "much discussion" about his post and that he wished to explain his intentions. He described Kirk as "a Christian, a father, and a husband." He added that "regardless of the circumstances, the fact that he lost his life in a shooting while giving a lecture in front of countless college students is a heartbreaking tragedy beyond any political stance. That is why I paid tribute to him." Choi said he deleted the posts after feeling that his "intentions were misunderstood." He explained that he believed his "sincere feelings had already been conveyed".[80]

Career

Debut and early group activities with Super Junior

Choi Si-won debuted as a member of the South Korean boy group Super Junior on November 6, 2005, performing the lead single "Twins (Knock Out)" during their first appearance on SBS's Popular Songs (later known as Inkigayo). Within the 12-member lineup, initially branded as Super Junior 05, Si-won was positioned as a sub-vocalist, visual, and center, contributing to the group's emphasis on synchronized choreography and vocal harmonies amid the competitive early-2000s K-pop landscape dominated by solo acts and smaller ensembles. His role helped establish Super Junior's image as a versatile, multi-faceted unit capable of blending pop, rock, and trot influences, which differentiated them from contemporaries and laid groundwork for sustained relevance despite high member turnover risks in the industry. The group's self-titled debut album, Super Junior 05 (TWINS), followed on December 5, 2005, peaking at number three on South Korea's monthly charts and selling 28,536 copies in its first month, a modest but foundational success that outsold several rival debuts and signaled growing fan engagement through fan-subbing communities and early Asian promotions. Subsequent releases, including the 2007 mini-album Don't Don, amassed over 225,000 units sold, bolstering domestic chart performance and introducing experimental tracks that showcased group dynamics, with Si-won's visual presence enhancing music video appeal and live stage charisma during promotional cycles. These efforts culminated in 2009 with the third studio album Sorry, Sorry, released March 12, whose title track drove massive replay value through its addictive dance routine, propelling the album to become South Korea's best-selling record of the year within one month and expanding Super Junior's footprint via SM Town concert circuits across Asia. Early group activities emphasized rigorous promotions, including television appearances and fan meets, which fostered loyalty amid scandals affecting other idols, while Si-won's contributions to vocal sections and center positioning in formations supported the unit's adaptability—transitioning from project-group origins to a fixed lineup by 2006. This period marked Super Junior's in sustaining momentum against fleeting trends, with cumulative album sales exceeding 400,000 units by 2009, enabling international outreach through dubbed releases and setting precedents for K-pop's global scalability via coordinated group synergy rather than individual stardom.

Sub-unit participation in Super Junior-M

The subunit's establishment aimed to adapt 's music into for greater accessibility in and , leveraging members' language abilities for localized promotions. Si-won's inclusion stemmed from his pre-debut training in Mandarin facilitated by , which positioned him as a key vocalist and visual contributor fluent enough to handle interviews and fan interactions in the language. The subunit released its debut studio album Me on April 23, 2008, featuring tracks like "Love U" and achieving initial sales exceeding 10,000 copies in Asia. Subsequent mini-albums included Super Girl on September 24, 2009, which sold 4,411 copies in South Korea per Gaon data, and Perfection on February 28, 2011, emphasizing polished Mandopop production. Their second studio album Break Down, issued January 7, 2013, marked a commercial peak with over 56,000 units sold, promoted via a Beijing press conference and Chinese media appearances despite growing cross-strait regulatory scrutiny on foreign entertainment. Si-won balanced these subunit commitments alongside main Super Junior schedules, contributing vocals and stage presence to tracks tailored for Chinese audiences. Promotions emphasized live performances and tours in , including segments of the series with dedicated Mandarin sets, though specific subunit-only tour data remains limited to regional fan meets and album showcases through 2015. Si-won's Mandarin proficiency notably aided rapport-building, as seen in events like appearances where he led communications.

These projects highlighted his versatility in genres ranging from romance to industry critique, with earning praise for its meta-examination of TV production ethics and Choi's embodiment of a Hallyu star's entitlement. By 2015, he expanded into film with the multinational crime thriller , directed by Longman Leung and Sunny Luk, playing the South Korean agent Park Woo-cheol in a plot involving a stolen nuclear device; the film featured an ensemble cast including and and grossed over HK$20 million in its opening weekend in .

Controversies

Animal ownership incident

On September 30, 2017, a 10-kilogram named Bugsy, owned by the family of singer-actor Choi Si-won, bit the leg of a neighbor in an apartment elevator in Seoul's Gangnam-gu district. The dog was not restrained by a or muzzle, in violation of local animal control guidelines requiring pets to be controlled in shared spaces. The victim, a 53-year-old businesswoman surnamed Kim and co-CEO of the upscale restaurant chain Hanilkwan, received immediate medical attention for the wound but developed from bacteria commonly found in canine saliva. She died on October 6, 2017, six days after the attack. Choi Si-won, who was serving mandatory military service at the time and did not reside with the family, publicly apologized via social media, expressing deep responsibility as a family member involved in the dog's ownership. His father, Choi Jin-ki, also issued statements of remorse, noting the bite was accidental and offering condolences. The victim's family forgave the Chois, declined to seek compensation, and stated they would leave decisions on the dog's fate to the owners' conscience, with no civil lawsuit pursued. South Korean authorities investigated under the Animal Protection Act, which mandates owners ensure pets do not harm others and imposes fines for unrestrained animals in public or communal areas. The Choi family received an administrative fine of 50,000 (approximately 44 USD at the time) from Gangnam-gu officials for the leash violation, with no finding of contributing to the fatality, as the sepsis stemmed from a rare, unpredictable bacterial complication rather than wound severity. No criminal prosecution followed, though the case exposed enforcement gaps in pet ownership laws, prompting the Ministry of Agriculture, Food and Rural Affairs to propose amendments, including fines up to 200,000 won for first offenses and mandatory training for owners of potentially aggressive breeds. Prior to the incident, South Korean regulations emphasized basic restraint but lacked stringent penalties or registration requirements, contributing to public outcry over accountability.

Backlash over public statements and social media posts

In September 2025, Choi Si-won faced significant criticism after reposting a tribute on Instagram to Charlie Kirk, a U.S. conservative activist and founder of Turning Point USA, who was fatally shot on September 10. The post, shared from a Christian community account, expressed prayers for Kirk's family and emphasized shared values on faith and family amid national grief, but it drew accusations from fans and online commentators of endorsing Kirk's opposition to progressive policies on issues like abortion and gender ideology. Choi deleted the post shortly after, stating it was a personal expression of mourning rooted in Christian solidarity rather than political alignment, and that misinterpretation prompted its removal to avoid unintended controversy. The Kirk tribute intensified calls for Choi's removal from , with fans launching hashtags like #SiwonOut and creating dedicated accounts demanding his expulsion, citing harm to the group's image among international audiences sensitive to conservative associations. Rumors circulated of internal group tensions, including claims that leader had unfollowed Choi on , though neither confirmed such actions. Defenders, including some longtime fans, argued the backlash infringed on free speech and overlooked Kirk's documented advocacy for religious liberty and traditional ethics, positions aligned with Choi's public Christian faith rather than extremism. Later that month, on September 29, Choi reposted a video on Instagram Stories depicting Nigerian Christians praying amid destroyed churches, captioning it to highlight resilience against "Islamist" militants' attacks. This drew renewed accusations of Islamophobia and racism from critics, who labeled the post selective for not addressing other global conflicts and claimed it generalized about Muslims. Choi issued an apology, clarifying intent to commend persecuted believers' faithfulness, but it fueled further outrage and revived #SiwonOut trends. Empirical reports confirm ongoing violence against Nigerian Christians by groups like Boko Haram, with over 50,000 deaths and thousands of churches razed since 2009 per data from organizations tracking religious persecution, contextualizing the post's focus on verifiable extremism rather than blanket prejudice. These incidents highlighted a pattern of polarized reactions to Choi's activity, where expressions of prompted demands for professional repercussions from portions of the fanbase, contrasted by arguments for expressive in non-work contexts. Left-leaning online outlets and fans often framed such posts as bigoted without engaging the underlying factual bases, such as documented faith-based or statistics, reflecting broader institutional biases in entertainment discourse that prioritize ideological conformity over empirical scrutiny.

Choi responded on on September 15, 2025, expressing love for fans despite the criticism and clarifying that his condolences were not politically motivated but stemmed from personal acquaintance, though this did little to quell demands for his departure. Perceived ideological divergences between Choi, known for his devout Christian conservatism, and members like Heechul, who has expressed more progressive stances on social issues, fueled speculation of internal friction. During Super Junior's 10 concert in on October 5, 2025, fan-recorded footage highlighted awkward onstage interactions, with Choi appearing to maintain physical distance from Heechul amid group performances, interpreted by observers as tension stemming from the recent . Similar observations of subdued camaraderie were noted in subsequent shows, contrasting with historical group unity, though no member has publicly confirmed rifts.
