Oh Sion is a South Korean singer and the leader of NCT Wish, a sub-unit of the K-pop group NCT. He debuted with the group in February 2024 and serves as its lead vocalist, known for his stable live singing and bright stage presence. As of 2026, NCT Wish has released multiple singles and albums, building a dedicated fanbase in both South Korea and Japan. Oh Sion is recognized for his energetic persona and his role as the group's mood maker.[edit]

Oh Sion was born on May 11, 2002, in Mokpo, a coastal city in South Jeolla Province. He grew up with his parents and an older brother. As a child, he was active in sports, particularly swimming and soccer, and developed an early passion for music after watching K-pop performances. He learned to play the piano and guitar during his school years. After auditioning for SM Entertainment, he became a trainee and spent several years honing his singing and dancing skills. In 2023, he participated in the pre-debut survival show NCT Universe: LASTART, where he competed for a spot in the final lineup of a new NCT sub-unit. His performances on the show showcased his vocal ability and leadership qualities, earning him a place in the debut group.[edit]

Oh Sion debuted as the leader and lead vocalist of NCT Wish on February 21, 2024, with the single "Wish." The debut single album charted on the Circle Album Chart and the Oricon Albums Chart. In July 2024, the group released their first Korean comeback single "Songbird." In 2025, NCT Wish released their first studio album Steady and held their first solo concert in Seoul. That same year, Oh Sion released his first solo work, the OST "I'm Still Here" for the drama Dear Hyeri. In 2026, the group has been active in Japan, releasing the Japanese single "Hands Up" and embarking on a fan-con tour across Asia. Oh Sion has also appeared as a guest on variety shows such as Knowing Bros and served as a special MC for M Countdown.[edit]

Oh Sion is known for his bright, youthful, and energetic aesthetic, often seen in colorful, casual streetwear or preppy styles. His wide smile and eye smile are frequently highlighted by fans. The media portrays him as a cheerful, hardworking leader who takes care of the younger members, and he is praised for his vocal stability and stage presence. NCT Wish's official fandom name is WISHful, and fans hold "wishing" events where they write messages on paper stars for the group. On official group accounts, his posts are positive and encouraging, often including many emojis and behind-the-scenes content.[edit]

Oh Sion stands as a central figure in the current K-pop landscape, leading NCT Wish with a vocal stability that has earned him a dedicated following across South Korea and Japan. While he commands significant attention within the SM Entertainment ecosystem, iFANN's Global Fame Engine evaluated his standing in August 2026 and determined that he currently holds no placement in the published Global Top 1,000 rankings or any Top-100 scope list. This absence of a specific numeric rank reflects his status as a rising star whose global metrics are still maturing compared to veteran idols, yet his influence remains potent through high-engagement fan interactions. The collective audience supporting him operates under the umbrella name NCTzen, the official fandom for all NCT sub-units, rather than a unique moniker dedicated solely to Sion. Fans demonstrate their loyalty through massive mobilization efforts, such as the 33,000 attendees who filled Seoul for the group's April 2026 encore concert. However, the dynamic between idol and fan is not without its complexities; a notable incident in August 2025 saw Sion confronted by an angry fan during a meet-and-greet, sparking widespread debate about fan behavior. His personal life also draws intense scrutiny, highlighted by a variety show appearance in April 2026 where he discussed his dating history, generating strong reactions from the community. Beyond these moments, his collaboration on EXO's Sehun single "Fade" in July 2026 further cemented his place among senior artists, proving his reach extends beyond his immediate unit.[edit]

Before stepping onto the stage, Oh Sion was a competitive swimming athlete during his elementary school years, building a foundation of discipline that serves him now. He began learning piano and guitar as a child, skills that contribute to his musical versatility today. Citing EXO's Baekhyun as his role model, Sion has cultivated a bright, energetic persona that earns him the title of NCT Wish's "mood maker." His ability to speak some Japanese, acquired during trainee years for the group's debut in Japan, allows him to connect deeply with fans across borders. One of the most enduring stories in his career involves the intense atmosphere of fan interactions, specifically a viral moment from August 2025 where a fan yelled at him during a meet-and-greet, an event that became a focal point for discussions on idol safety. Another chapter of his public narrative opened in April 2026 when he revealed details about his past dating history on a variety show, a disclosure that sparked fierce debates within the fandom. His artistic range was further showcased in a visual moment from the "Surf" music video, where he appeared alongside baseball player Yang Hyun-jong, hinting at his potential beyond standard idol performances.[edit]

Oh Sion has an older brother. He grew up in Mokpo with his parents. Details about his parents' occupations are not publicly known. He has not publicly mentioned any pets.[edit]

Oh Sion is closely associated with his NCT Wish groupmates: Riku, Yushi, Jaehee, Ryo, and Sakuya. As an SM Entertainment artist, he frequently interacts with seniors from NCT 127, NCT Dream, WayV, aespa, and EXO at company events.[edit]

As of 2026, Oh Sion has no confirmed public romantic relationships. He has not been linked to anyone, and credible outlets have not reported any dating history. In interviews, he has stated that he is focused on his career and group activities.[edit]

Per iFANN's editorial analysis, Oh Sion's individual net worth is estimated at $1 Million as of 2026. His primary income streams include his share of NCT Wish's album sales, concert revenue, brand endorsements involving partners like Pepsi and Lotte, and fees from variety show appearances and MC gigs. As a relatively new idol, his personal earnings remain modest compared to established artists, but his financial prospects are expected to grow alongside the group's expanding popularity.[edit]
