He is widely regarded as one of the wealthiest Super Junior members, with an estimated net worth of $18 million as of 2026.

Beyond music, Si-won has taken on leading roles in television dramas such as Oh! My Lady, Athena: Goddess of War, She Was Pretty, and My Fellow Citizens!, and appeared in the Hong Kong film A Battle of Wits alongside Andy Lau. He has also been active in Super Junior's Chinese sub-unit, Super Junior-M, and the sub-unit Super Junior-L.S.S. He continues to release new music and tour with the group. His philanthropic efforts and open sharing of his faith have earned him a dedicated global fanbase, and he serves as UNICEF East Asia and Pacific Regional Office ambassador.

Choi Si-won was born in Seoul, South Korea, on April 7, 1986. He attended Apgujeong High School, graduating in February 2006, and later earned a bachelor's degree in Theater and Film from Inha University in February 2012 alongside Super Junior bandmate Kim Ryeowook. He subsequently completed a master's degree and a Ph.D. in Cultural Management at the same institution. During his teenage years, he developed interests in music, dance, modeling, and athletics, becoming known for his striking looks and athletic build.

In 2002, at age 16, an SM Entertainment scout spotted him on the street near his school and invited him to audition through the Starlight Casting System. He initially hid the audition from his strict parents, who disapproved of an entertainment career, but passed and signed with SM after they eventually relented. His father reportedly refused to provide financial help, insisting Si-won succeed independently. As a trainee, he underwent rigorous training in singing, dancing, acting, and languages while making small cameo appearances in television dramas such as Precious Family (2004) and Eighteen, Twenty-Nine (2005), plus modeling work to build visibility.[edit]

Si-won's breakthrough came on November 6, 2005, when he debuted as a member of Super Junior (initially Super Junior 05) with the single "Twins (Knock Out)" from the album Twins. His visual appeal and stage presence quickly made him one of the group's most popular members. In 2006, he expanded into acting with his first major film role as Prince Liang Shi in the Hong Kong historical action film A Battle of Wits, starring alongside Andy Lau; this project introduced him to Chinese-speaking audiences. In 2008, he joined Super Junior-M, the group's Mandarin-focused sub-unit, performing under the Chinese name Shiyuan; their debut single "U" targeted the Chinese market. His Korean acting career accelerated in 2010 with leading roles in the romantic comedy Oh! My Lady (opposite Chae Rim) and the action series Athena: Goddess of War (as a data analyst and rookie elite agent). These projects earned him the SBS Drama Awards New Star Award in 2010.

Throughout the 2010s, Si-won balanced Super Junior's albums, world tours, and sub-unit activities with acting in both Korea and China. Notable dramas include She Was Pretty (2015), for which he won the 2016 Drama Fever Award for Best Supporting Actor, and My Fellow Citizens! (2019), which brought him the 2019 Asia Artist Awards Best Icon Award in Television and the KBS Drama Awards Excellence Award, Actor in a Mid-length Drama. He enlisted for mandatory military service on November 19, 2015, serving as a conscripted police officer in a promotional unit until his discharge on August 18, 2017. Post-military, he continued acting with projects such as Revolutionary Love (2017), Love Is for Suckers (2022; earning 2022 Asia Artist Awards for New Wave Award (Actor) and Best Acting Performance), and streaming series including Work Later, Drink Now and Heart Pairing. In July 2023, he debuted with Super Junior-L.S.S. (with Leeteuk and Shindong) and their single "Close The Shutter." As of 2026, he remains active in group comebacks, concerts, solo acting, modeling, and philanthropy.[edit]

Choi Si-won is widely known as the 'visual' and 'prince charming' of Super Junior, celebrated for his striking looks, athletic physique, and devout Christian faith. Media and fans often describe him with nicknames like 'The Bodyguard,' 'Sculpture Man,' and 'Simba,' reflecting his muscular build and charismatic stage presence. His personal style blends classic elegance with modern fashion, frequently appearing in tailored suits and casual athletic wear. Si-won maintains a polished, positive, and faith-oriented social media voice on Instagram and Twitter, where he shares Bible verses, workout videos, and promotional content. His official fandom is Super Junior's ELF (Ever Lasting Friend), and fan culture includes enthusiastic cheering rituals and engagement with his spiritual and fitness posts. He is perceived as sincere, philanthropic, and dedicated to his craft, balancing a successful group career with solo acting and modeling.[edit]

Choi Si-won operates within the massive, highly organized ecosystem of Super Junior's fanbase, E.L.F., though he has cultivated a distinct layer of devotion often referred to by fans as 'Siwonest.' This community is renowned for its logistical prowess, executing global streaming campaigns and funding charitable initiatives that reflect Si-won's own advocacy for animal welfare and children with disabilities. While the group identity remains paramount, Si-won's unique persona as the 'King of Variety' and his recent shift toward outspoken political engagement have deepened this bond, creating a dedicated following that navigates both his comedic legacy and his controversial public stances. The audience remains fiercely protective, particularly during periods of digital security breaches or intense media scrutiny.

His standing in the global entertainment landscape reflects this sustained relevance and multifaceted career spanning nearly two decades. According to the iFANN Global Fame Rankings, Choi Si-won is the 74th most famous person in K-Pop, a position noted as down from 71st last cycle. These placements, which track global attention across media coverage, search, and consumption signals worldwide, underscore his enduring status as a central figure in the industry.[edit]

Choi Si-won is celebrated for his devout Christian faith, frequently sharing Bible verses on social media and even earning the nickname 'Shisus' as a play on Jesus. Born into an affluent family whose parents reportedly own a large supermarket chain and operate Boryung Medicine, he served his military service as a conscripted police officer in a promotional unit rather than standard army duty. Fluent in Korean, English, and Mandarin, he leveraged these skills to connect deeply with Chinese fans. His fitness obsession is legendary, resulting in nicknames like 'Sculpture Man,' 'The Bodyguard,' and 'Simba,' while his registered birthdate was once listed as February 10, 1987, before being corrected to April 7, 1986.

A defining legend surrounding Si-won is his title as the 'King of Variety' within Super Junior, where he embraced the role of the 'sacrificial lamb' on shows like *Running Man* and *Love Letter*. More recently, a complex web of lore has emerged from 2026 controversies, including a viral moment where he defended national pride over diplomatic silence regarding a flag banner incident. Fans also recount the 'digital folklore' of the August 2026 SNS hacking, where unauthorized posts led him to issue emergency appeals, cementing his reputation as a star who refuses to stay silent amidst political storms.[edit]

Choi Si-won was born into an affluent, strict Protestant Christian family. His father, Choi Ki-ho, served as former CEO of the pharmaceutical company Boryung Medicine (with some reports linking the family to a large supermarket chain), and his mother is Byun Jae-jeong. He has one younger sister, Choi Ji-won. Raised with strong religious values, Si-won has remained a devout Protestant Christian throughout his career, frequently sharing Bible verses and faith-based content on social media. He is known to be close to his family and often speaks about their influence on his faith and values.[edit]

Si-won is closely associated with his Super Junior bandmates, especially members who also act, such as Lee Donghae and Choi Si-won's frequent collaborator, Kim Heechul. He has worked with actor Andy Lau in the film A Battle of Wits and has been linked to Indonesian singer Agnez Mo in unconfirmed dating rumors. He is also known for his friendship with fellow SM Entertainment artists. [edit]

Si-won has kept his romantic life largely private, with few confirmed relationships. The only repeatedly reported pairing is a publicly rumored relationship with Indonesian singer and actress Agnez Mo (also known as Agnes Monica). Rumors began in 2015 after the pair were spotted together at events and collaborated professionally; neither party ever confirmed a romance, and it ended without public statements. As of 2026, Si-won is reportedly single, with no public partner or marriage. He has never been married and has no known children.[edit]

Updated for 2026, iFANN currently estimates Choi Si-won's net worth at $18 million, placing him among the wealthiest members of Super Junior. His substantial earnings stem from a diverse portfolio including music activities with Super Junior, album sales, concert tours, and merchandise. He commands significant fees for leading roles in Korean and Chinese dramas and films, alongside lucrative modeling contracts and brand endorsements for fashion and lifestyle companies. The financial foundation laid by his family's business interests, specifically their ownership of a large supermarket chain and his father's pharmaceutical company Boryung Medicine, further bolsters his economic standing. Unlike many peers, Si-won has not publicly disclosed major real estate or investment holdings, yet his long career and varied income streams have ensured steady wealth growth.[edit]

Choi Si-won has won several awards for his acting, including recognition at Korean drama and film award ceremonies. He has been honored for his performances in both television and film, though specific award names and years are not widely documented in English sources. [edit]
