Riwoo (리우) is a South Korean singer, dancer, and member of BOYNEXTDOOR.
Lee Sang Hyeok, better known by his stage name Riwoo, was born on October 22, 2003, in South Korea. From a young age, he developed a passion for dance and performance, eventually pursuing formal training while attending Hanlim Multi Art School, one of South Korea's most well-known performing arts schools. His dedication and natural talent helped him build the skills that would later earn him a place in one of K-pop's most promising fourth-generation groups.
Riwoo debuted in 2023 as a member of BOYNEXTDOOR under KOZ Entertainment. As the group's main dancer, he is known for his smooth movements, strong stage presence, and ability to bring emotion into performances. While he tends to be quieter than some of his members, his charm, humor, and genuine personality have made him a favorite among fans worldwide.
Fan-made pieces inspired by drama nights, bias feelings, and soft delulu moods.
Fans love Riwoo because he perfectly balances cool stage charisma with an unexpectedly adorable off-stage personality. On stage, he commands attention with his dance skills and confidence, but behind the scenes, he's often shy, thoughtful, and surprisingly funny. His tendency to express himself through writing rather than words makes many fans feel they are seeing a more genuine side of him.
Another reason fans adore Riwoo is his relatable nature. Whether he's talking about eating an absurd number of doughnuts, showing affection for his dog, or making dad jokes that leave the members groaning, he comes across as authentic and approachable. His quiet warmth and subtle sense of humor have helped him build a devoted following among ONEDOORs.
