The Evolution of ZEROBASEONE: Navigating a New Chapter in K-Pop

Since their explosive debut in 2023, ZEROBASEONE (ZB1) has remained a central figure in the K-pop landscape. Formed through the Mnet reality competition Boys Planet, the group quickly cemented their status as industry powerhouses. As of May 2026, the group continues to evolve, maintaining a prominent presence in the music industry despite significant shifts in their lineup and management structure.

A Journey Defined by Success

Managed by WakeOne, ZEROBASEONE burst onto the scene on July 10, 2023, with their debut EP, Youth in the Shade. The project was an immediate commercial success, selling over two million units and topping the South Korean Circle Album Chart. Their impact was recognized globally, with the International Federation of the Phonographic Industry (IFPI) naming the EP one of the best-selling albums of the year. Their lead single, “In Bloom,” further expanded their reach by charting on the Billboard Global 200.

The group’s rapid ascent was marked by a “Rookie Grand Slam” achieved between 2023 and 2024. They secured ten Rookie of the Year awards across major domestic ceremonies, including the Golden Disc Awards, MAMA Awards, Melon Music Awards, and the Seoul Music Awards.

Transition and Current Lineup

The group’s structure underwent a major transformation in March 2026. Following the expiration of their contracts, four original members—Zhang Hao, Ricky, Kim Gyu-vin, and Han Yu-jin—concluded their activities with the group. This change marked a new chapter for the remaining members: Kim Ji-woong, Sung Han-bin, Seok Matthew, Kim Tae-rae, and Park Gun-wook.

Despite these changes, the group’s commitment to their craft remains steady. Sung Han-bin continues to lead the ensemble, which maintains its active schedule, including television appearances such as the May 2026 broadcast of MBC’s Show! Music Core.
