Mark Lee

Mark Lee (born August 2, 1999) is a Canadian rapper, singer, and songwriter based in South Korea. He rose to prominence as a member of NCT, appearing in its sub-units NCT 127 and NCT Dream, and later joined the supergroup SuperM. Known for his sharp rap delivery and energetic stage presence, Mark became one of K-pop's most recognizable young stars. On April 7, 2025, he made his solo debut with the studio album The Firstfruit, a deeply personal project that showcased his songwriting and vocal range. After his contract with SM Entertainment expired on April 8, 2026, he announced his departure from NCT and launched his own label, Upper Room, on June 3, marking a new chapter in his career.[edit]

Mark grew up in a Korean-Canadian household in Toronto's North York suburb. He attended local elementary and middle schools, where he developed an early interest in music and performance. At age 13, he auditioned for SM Entertainment's 2012 Global Audition in Canada and passed. In 2013, he moved to Seoul alone to begin training as a K-pop trainee. For three years, he learned Korean, refined his rapping and dancing, and adapted to a new culture. He attended Seoul Performing Arts High School but left before graduating due to his busy schedule, later earning a GED certification.[edit]

Mark debuted on April 9, 2016, with NCT U, releasing the single The 7th Sense. That same year, he joined NCT 127, and in 2017, he debuted with NCT Dream. In 2018, he competed on the survival show High School Rapper, finishing as runner-up and raising his individual profile. In 2019, he was selected for SuperM, a supergroup formed by SM Entertainment and Capitol Records. SuperM's debut EP reached No. 1 on the Billboard 200, making them the first K-pop act to top the chart with a debut release. SuperM released their first full-length album Super One in 2020 and embarked on a world tour. In 2023, Mark graduated from NCT Dream's rotational system. On April 7, 2025, he released his solo debut album The Firstfruit. After his SM contract expired, he departed NCT in April 2026 and launched his own label, Upper Room, on June 3.[edit]

Mark is known for a clean, youthful, and athletic aesthetic, blending streetwear with high-fashion elements. His hair color and style change frequently, with blonde, silver, and dark brown being common choices. Media portray him as a hardworking, disciplined all-rounder capable of rapping, singing, dancing, and songwriting. His Canadian background is often highlighted. Fans informally call themselves Markzens or Markies. On Instagram, he posts behind-the-scenes content and personal snapshots with brief, casual captions in English and Korean.[edit]

Mark Lee has cultivated a deeply engaged following that transcends the standard group dynamic, evolving from the collective energy of NCTzen into a personal alliance driven by his unique trajectory. Fans identify strongly with his narrative as the "busiest man in K-pop," a title earned through his unprecedented 2016 debut across three separate units: NCT U, NCT 127, and NCT Dream. This historical feat created a mythology around his work ethic that remains central to his lore today. His digital presence is defined by active participation rather than passive observation; he frequently directs his audience toward the #MarktheMoveChallenge on Instagram, inviting fans to co-create content that supports his artistic vision. The emotional bond between Mark and his supporters was most visible during his departure from SM Entertainment in April 2026. When the announcement ended his decade-long tenure, the reaction was one of profound shock, with international outlets noting the intensity of the fanbase's loyalty as Mark shared a handwritten letter expressing gratitude for his journey. While no formal sub-fandom name exists exclusively for him, the community rallies behind his individual projects with the same fervor applied to his group activities. Despite this massive global footprint, iFANN's Global Fame Engine has evaluated Mark Lee but currently does not place him within its published rankings or scope lists.[edit]

Mark Lee holds the distinction of being the first Canadian-born K-pop idol to debut in three different groups simultaneously. A self-taught pianist, he often incorporates live piano into his solo performances, adding a layer of intimacy to his music. He is fluent in English and Korean, with working knowledge of Japanese and Chinese, allowing him to connect with diverse audiences globally. In interviews, he has consistently cited Korean fried chicken as his favorite food. On a personal note, he adopted a pet cat named Soon-ee (순이) while still a trainee. The story of his career is anchored by his legendary status as the busiest man in K-pop, a moniker born from his triple-unit debut in 2016 that fans still retell as a reflection of his versatility. Another defining moment in his folklore is the historic conclusion of his ten-year contract with SM Entertainment in April 2026, an event that sent shockwaves through the industry and marked the end of an era for the veteran idol.[edit]

Mark is the only child of Korean-Canadian parents. His father is Lee Chang-geun, and his mother is Kim Sun-young. He has a close relationship with his family, who supported his move to Korea at a young age. As of 2026, he lives in Seoul and has a pet cat named Soon-ee.[edit]

Mark has worked closely with SM Entertainment founder Lee Soo-man, who oversaw his training and career development. He frequently collaborated with fellow NCT and SuperM member Taeyong on rap tracks. In SuperM, he performed alongside Baekhyun, Kai, Ten, Lucas, and Jungwoo. His parents, Lee Chang-geun and Kim Sun-young, remain based in Toronto and have been supportive throughout his career.[edit]

Mark Lee has maintained a private personal life throughout his career. As of 2026, there are no confirmed public romantic relationships. While fan speculation and unverified rumors have circulated online regarding various female idols and acquaintances, none have been substantiated by credible Korean media outlets or official confirmation. As of 2026, Mark is reportedly single with no confirmed dating partners, engagements, marriages, or children.[edit]

Per iFANN's editorial analysis, Mark Lee's net worth stands at $10 Million as of 2026. This financial standing is built upon a decade of high-profile activity with NCT and SuperM, where album sales, concert tours, and digital streaming generated an estimated $3–4 million between 2016 and 2026. His solo debut, The Firstfruit, contributed approximately $1–2 million through sales and streaming figures. Strategic endorsement partnerships with major brands including Nature Republic, Nike Korea, and Samsung have added an estimated $1–1.5 million to his portfolio. Following the expiration of his contract in April 2026, he launched his independent label, Upper Room, in June 2026. This venture represents a new investment phase with projected income that has not yet been publicly reported. Details regarding specific real estate holdings remain undisclosed.[edit]

Mark Lee has won several individual awards for his solo debut. In 2025, he won Best Male Solo Debut at the Mnet Asian Music Awards, Best Solo Album at the Golden Disc Awards, Solo Debut of the Year at the Seoul Music Awards, Best Rap/Hip-Hop Album at the Korean Music Awards, and Solo Artist of the Year (Rap category) at the Asia Artist Awards.[edit]
