The next chapter for four familiar faces from ZEROBASEONE may be arriving sooner than many fans expected. According to March 18 reports, Zhang Hao, Ricky, Kim Gyuvin, and Han Yujin are preparing to re-debut in a new boy group called NDOUBLE this May, with reports pointing to May 26, 2026 as the target debut date. Just as importantly, coverage says YH Entertainment has confirmed that the four idols are preparing for debut, while adding that more details will be revealed later. At this stage, the group name and May debut plan have been widely reported, but the agency’s full rollout details have not yet been publicly finalized in the sources reviewed here.
What makes this news especially emotional for fans is the timing. ZEROBASEONE’s transition has only just taken shape. On February 12, 2026, WAKEONE confirmed that the group would continue as a five-member act with Sung Han Bin, Kim Ji Woong, Seok Matthew, Kim Tae Rae, and Park Gun Wook, while Zhang Hao, Ricky, Kim Gyu Vin, and Han Yu Jin would part ways with the project group and move on to their next steps. Korean and international coverage described this as the formal end of the original nine-member structure, closing one era while immediately opening questions about what would come next for the departing members.
That is why the reported NDOUBLE debut feels so significant. It is not simply a redebut story; it is the continuation of a bond and popularity that were already proven on one of the most visible stages in recent boy-group history. Zhang Hao, Ricky, Kim Gyuvin, and Han Yujin are not returning as unknown trainees trying to build recognition from scratch. They are returning with a built-in fandom, a well-established chemistry, and a shared history that many fans have already invested in emotionally. If NDOUBLE officially launches in May, the group will debut carrying both the affection attached to their ZEROBASEONE era and the pressure that comes with living up to it. The reported redebut timeline and agency confirmation suggest YH Entertainment understands that momentum and is moving quickly to turn it into a fresh beginning.
One of the most interesting parts of the current reporting is that NDOUBLE may not remain a four-member unit. Coverage says the new team is expected to include additional members, although the final lineup and total member count are still undecided in the information currently available. That uncertainty has naturally become a major talking point among fans. Some are excited by the possibility of a larger group identity and a more ambitious launch strategy, while others are especially attached to the idea of the four former ZEROBASEONE members promoting together as the emotional core of the new team. For now, the one thing that seems clear is that these four members are central to the project, even if the full picture of NDOUBLE has not yet been fully unveiled.
Among the four, Zhang Hao is likely to draw particular attention as NDOUBLE moves closer to debut. As the first-place winner of “Boys Planet,” he entered ZEROBASEONE with enormous visibility and quickly became one of the defining faces of the group. His technical skill, polished stage presence, and calm but commanding aura gave him a distinct role in ZEROBASEONE’s identity. A redebut under NDOUBLE could give him a new setting in which to evolve from project-group centerpiece into a foundational pillar of a longer-term act. That possibility alone is enough to make the upcoming debut one of the most watched post-project-group transitions of the year. Zhang Hao’s status as one of the four members leaving ZEROBASEONE and returning to YH Entertainment is confirmed in multiple reports.
Ricky, meanwhile, brings a very different kind of star power. He has consistently stood out for his image, confidence, and instantly recognizable charisma. In a new group setting, those qualities could become even more prominent. Redeuts often give idols the chance to reshape how they are framed—sometimes shifting from a striking supporting presence into one of the central drivers of a group’s concept. If NDOUBLE’s branding leans sophisticated, sharp, or globally marketable, Ricky could play a major role in defining that tone. This is an inference based on his established public image rather than a confirmed statement about the group’s concept, which has not yet been detailed in the cited reporting.
For Kim Gyuvin and Han Yujin, the redebut narrative is equally compelling, though for slightly different reasons. Both members built strong popularity through their growth arcs, youthful energy, and highly visible chemistry with the rest of ZEROBASEONE. A new debut could give them more room to deepen their individual identities while still preserving the team dynamic fans already love. In many post-survival-show redebuts, one of the biggest challenges is turning existing familiarity into a stronger, more mature artistic direction. That may be the key question NDOUBLE will have to answer: how to preserve the affection tied to these members’ past while presenting something fresh enough to feel like a true next chapter rather than simply an extension of what came before. Their participation in the new project is part of the March 18 reporting on NDOUBLE’s planned May launch.
The business side of the story is also worth paying attention to. YH Entertainment already had a strong position in this transition because all four members are signed to the agency, a detail noted when ZEROBASEONE’s future was officially clarified in February. That means the company is not building this project around newly assembled free agents; it is launching a group with artists already under one roof, already familiar to a large international audience, and already connected through a major project-group success story. Strategically, that creates a rare opportunity. Instead of spending years on pre-debut visibility, the agency can focus on concept, music, positioning, and fan retention from day one.
Another reason the NDOUBLE news has attracted so much attention is the calendar itself. Reports suggest that both NDOUBLE and the reorganized five-member ZEROBASEONE are preparing May activities, which raises the prospect of a month filled with parallel promotions tied to the same legacy. That overlap could turn May 2026 into a uniquely emotional period for fans: one branch of ZEROBASEONE moving forward under the original name, and another beginning again under a new one. In practical terms, it also means media comparisons will be inevitable. Fans and industry watchers will likely pay close attention to how each team defines its identity, sound, and direction after the split. The reports cited here note that ZEROBASEONE’s five-member comeback is also planned for May.
Culturally, stories like this tend to matter because they test whether survival-show fame can evolve into long-term group identity. Project groups are built around urgency: limited contracts, intense fan attachment, and a constant awareness that time is running out. A redebut like NDOUBLE has to transform that urgency into stability. It must convince fans that this is not simply an afterstory, but a main story in its own right. That is why this debut matters beyond the members involved. If successful, NDOUBLE could become one of the clearest examples of how post-project-group careers can be launched with continuity, emotional narrative, and commercial potential all at once. That assessment is an inference based on the members’ existing profile and the rapid agency-backed redebut timeline.
At the moment, some caution is still necessary. The available reporting supports that the four former ZEROBASEONE members are preparing to debut as NDOUBLE in May and that YH Entertainment has acknowledged the preparation, but not every detail is locked in publicly yet. The final lineup, official concept, and full promotional schedule have not been fully disclosed in the cited sources. Even so, the core development is already enough to make NDOUBLE one of the most talked-about upcoming boy-group launches of the season.
In the end, the story of NDOUBLE is about more than a name change or a fresh debut date. It is about continuity after transition. It is about four idols stepping out of one of the most closely watched project groups of their generation and trying to build something lasting on the other side. For Zhang Hao, Ricky, Kim Gyuvin, and Han Yujin, a May debut as NDOUBLE would mark not a restart from zero, but a reinvention built on everything they have already achieved. And for fans, that makes this next move feel less like goodbye—and more like the beginning of a new era.
