Sung Han-bin

Sung Han-bin (성한빈) is a South Korean singer, dancer, and leader of ZEROBASEONE. Born June 13, 2001 in Cheonan, he spent years competing in street dance circuits -- specializing in waacking and tutting -- before pivoting to idol training under Studio GL1DE, which he represented on Boys Planet. He ranked 2nd in the Boys Planet finale, making him ZB1's natural leader. His reputation going in was already built on dance credibility; what Boys Planet revealed was a performer who could hold a narrative and carry a group's identity. ZB1 debuted July 10, 2023 with Youth in the Shade, selling over two million copies and setting a debut pre-order record in K-pop at the time. The group swept all 10 domestic rookie-of-the-year awards and became five-time consecutive million-sellers. Han-bin anchored ZB1 through its debut season, its Blue Paradise era in 2025, and the RE-FLOW farewell album in February 2026. Alongside group activities, he has built a solo hosting presence: he covered individual days at 2024 KCON Japan and KCON Hong Kong, and made history by becoming the first artist to host all three days at 2025 KCON Japan. He is signed to both Studio GL1DE and THE L1VE. When four members departed in January 2026, Han-bin led the remaining five -- himself, Kim Ji-woong, Seok Matthew, Kim Tae-rae, and Park Gun-wook -- as ZB1 continued into an extended run through early 2026.
