Riwoo

Riwoo is a South Korean singer, dancer, and choreographer, best known as the main dancer and lead vocalist of the K-pop boy group BoyNextDoor. Born Lee Sang-hyeok on October 22, 2003, in Seoul, he debuted with the group on May 30, 2023, under KOZ Entertainment. Riwoo is recognized for his powerful dance skills and charismatic stage presence, often contributing to the group's choreography. As of 2026, BoyNextDoor has released multiple EPs and toured internationally, building a dedicated fanbase called ONEDOOR. Riwoo's journey from backup dancer to K-pop idol showcases his dedication and talent, and he continues to grow as a performer.[edit]

Riwoo grew up in the Beon-dong neighborhood of Seoul. He attended Hanlim Multi Art School, a prestigious arts high school, where he majored in practical dance. Before joining KOZ Entertainment, he worked as a backup dancer, gaining valuable stage experience. This background is relatively rare among K-pop idols, who typically debut without professional performance credits. He successfully auditioned for KOZ Entertainment and trained intensively in singing, rapping, and choreography alongside his future groupmates, preparing for the group's debut.[edit]

Riwoo debuted as a member of BoyNextDoor on May 30, 2023, with the single album WHO!, led by the track "But I Like You." The group quickly gained attention for their relatable "boy-next-door" concept. They released their first EP WHY.. on September 4, 2023, followed by the second EP HOW? on January 15, 2024, which included the hit "Earth, Wind & Fire." In 2024, they made their Japanese debut with the single "AND" on April 15 and released their third EP 19.99 on September 2. The group embarked on their first international tour, "KNOCK ON Vol.1," performing across Asia, the United States, and Europe. Riwoo has contributed to choreography for several of the group's songs, showcasing his dance expertise.[edit]

Riwoo is known for his sharp, powerful dance moves and cool stage presence, often described as the group's "dance machine." Offstage, he has a gentle, quiet demeanor and is seen as a reliable hyung (older brother) figure. His Instagram feed features aesthetic photos and dance clips. Fans appreciate his thoughtful interactions on WeVerse, where he often leaves encouraging messages. The BoyNextDoor fandom, ONEDOOR, supports him through organized streaming parties and fan projects.[edit]

Riwoo stands as the visual anchor of BOYNEXTDOOR, a rookie act that quickly transformed from Seoul newcomers to global sensations. His journey is defined by the sharp contrast between his petite stature and explosive stage power, a dynamic that fans have turned into a defining lore. The collective fanbase has mobilized with remarkable speed since the group's May 2023 debut. They champion Riwoo through organized streaming parties that drive chart momentum for releases like 19.99, while viral edits highlighting his choreography credits on tracks like But I Like You flood social feeds. Fans often celebrate his "Gen Z swag" and relatable anecdotes shared during interviews, fostering a community built on the idea of the accessible boy next door. This digital engagement extends to Weverse, where Riwoo's encouraging replies have become a ritual for supporters seeking connection beyond the screen. Despite this intense activity, the iFANN Global Fame Engine has evaluated Riwoo but does not currently hold a placement in the published rankings (Global Top 1,000 or a Top-100 scope list). As of August 2026, the fanbase has no formal documented name.[edit]

Riwoo's stage name was crafted by his agency; "Ri" echoes his surname Lee, while "Woo" evokes rain or friendship in Korean. An ISFJ personality type, he finds solace in movies and R&B, citing EXO's Kai as his primary dance inspiration. He actively shapes the group's performance history, contributing choreography to their debut hit But I Like You and subsequent tracks. Offstage, he cultivates a gentle reputation, often leaving thoughtful messages for fans on Weverse.

A central pillar of fan folklore surrounds Riwoo's physical presence within the lineup. As the shortest member of BOYNEXTDOOR, his height difference against taller members like Sungho and Leehan became an instant inside joke and a focal point of affection. Fans frequently highlight this contrast in video edits, turning a simple physical trait into a beloved symbol of the group's dynamic. Another enduring story emerged from his June 2023 appearance in the "30 Questions" interview, where his candid answers about personal preferences helped solidify his relatable persona. These moments, combined with the group's rapid international expansion to Japan, form the early legends of his career, proving that even in a short span, Riwoo has carved out a unique space in the hearts of Nextdoorers.[edit]

Riwoo keeps his family life private. He has not publicly disclosed details about his parents or siblings. As of 2026, he lives in Seoul, likely in a dorm with his group members. He has not mentioned any pets.[edit]

Riwoo is a member of BoyNextDoor alongside Sungho, Jaehyun, Taesan, Leehan, and Woonhak. His mentor is Zico, the founder of KOZ Entertainment. He has collaborated with other HYBE Labels artists for special stages and events.[edit]

Riwoo has no public dating history. Since his debut in 2023, he has not been involved in any confirmed or rumored romantic relationships. As of 2026, he is reportedly single, and his personal life remains private.[edit]

iFANN currently estimates Riwoo's net worth at $750 Thousand heading into 2026. This valuation reflects his earnings from BoyNextDoor's robust group activities, including album sales, streaming revenue, concert tours, and fan meetings. The collective has surpassed 1 million cumulative album sales, generating significant income split among the members. Additional financial support comes from endorsement partnerships with major brands such as ACUVUE, KB Kookmin Bank, and Lotte Chilsung. KOZ Entertainment manages his compensation through a salary and profit-sharing structure. While specific figures regarding his choreography credits remain private, these professional contributions add to his overall financial profile as a multifaceted performer.[edit]
