Four Former ZEROBASEONE Members to Re-Debut as AND2BLE in May

Three days after their final bow as a nine-member group, four former ZEROBASEONE members are already building what comes next. Zhang Hao, Ricky, Kim Gyuvin, and Han Yujin are set to debut as a new group under YH Entertainment on May 26, 2026, with the reported name AND2BLE (also circulating as NDOUBLE). According to YH Entertainment's official statement on March 18: "It is true that they are preparing for their debut. Details will be announced later on."

That confirmation landed exactly 72 hours after ZEROBASEONE's HERE&NOW encore concerts wrapped at KSPO Dome in Seoul. Thirty thousand fans packed in over three nights to mark the end of the nine-member era, as reported by WakeOne Entertainment's concert summary. The tears were real. So was the turnaround.

Why These Four

The split was always structural, not personal. Zhang Hao, Ricky, Gyuvin, and Yujin were never WakeOne artists. They came into ZEROBASEONE as YH Entertainment (formerly Yuehua) trainees, competing on Mnet's Boys Planet in 2023 and placing high enough to debut with the group. The joint management arrangement ran its course when the contract period ended in early 2026. In January, YH telegraphed the move with a "future activities notice" confirmed via Soompi, stating the four would return to their agency and explore options. The May debut report confirms what those options turned out to be.

Fans had already nicknamed these four the "Golden Line" long before any split was official. Zhang Hao anchored ZB1 as center and main dancer. Ricky, the group's youngest Chinese member, built a dedicated fanbase around his sharp stage presence. Gyuvin's personality and vocals made him one of ZB1's most visible members outside formal promotions. And Yujin, the group's youngest member overall, became a fan favorite from his Boys Planet days onward. YH is not starting from scratch with this group. They're working with four artists who already have an established fanbase, chart presence, and international reach.

The Name Question

The group name has not been officially confirmed. According to Korean media reports including AllKPop and Soompi, the name has appeared as AND2BLE, NDOUBLE, and ANDOUBLE interchangeably, reflecting multiple trademark filings YH made in the lead-up to the announcement. Fan reaction to NDOUBLE on social media was pointed, with comments ranging from confused to outright dismissive. The stylized AND2BLE reads cleaner, and it's likely the version YH leans into for marketing, but nothing is locked until the official reveal. The group will reportedly add members beyond the four former ZB1 members, with additional trainees to be introduced ahead of the May debut.

Meanwhile, ZEROBASEONE Moves On Too

The five remaining members of ZEROBASEONE, Sung Hanbin, Kim Jiwoong, Seok Matthew, Kim Taerae, and Park Gunwook, are continuing under WakeOne. A new album under the ZEROBASEONE name is also targeting May 2026 as confirmed by WakeOne's schedule announcement, meaning both lineups will be active in the same release window. That parallel launch strategy says a lot about where the industry sees the demand. ZB1 as a brand still carries weight. YH knows the four members they have carry weight of their own.

We have been tracking the post-contract trajectory of ZB1 since the January agency statement, and this is the cleanest possible outcome for both sides. Two groups, one gene pool, two separate May comebacks. K-pop fans have managed messier splits with less warning. This one, at least, was handled with some care.

AND2BLE's official debut date of May 26 has not been confirmed by YH Entertainment directly. Follow for updates as the official announcement drops.
