Just one day after reports of ZEROBASEONE's May comeback as a five-member group, new rumors suggest four former members may be forming their own group.

Zhang Hao, Ricky, Kim Gyu Vin, and Han Yu Jin are rumored to debut in a new group called NDOUBLE on May 26, according to industry reports. The group would include additional members beyond the four former ZEROBASEONE artists.

The timing aligns with our previous report about ZEROBASEONE preparing their first comeback as a reorganized five-member group, also planned for May. This would mean both the remaining members and the departing members could be releasing new music around the same time.

A source from the members' agency responded to the reports but has not provided confirmation of the debut plans. The lack of official denial has kept speculation alive among fans.

The four members were part of ZEROBASEONE's original nine-member lineup formed through the survival show "Boys Planet." Zhang Hao served as the group's main vocalist, while Ricky was known for his rap skills and visual appeal. Kim Gyu Vin contributed as a vocalist and dancer, and Han Yu Jin, the youngest member, brought energy as the group's maknae.

If confirmed, NDOUBLE would mark a fresh start for these artists after their time in the temporary project group. The May 26 debut date would put them in direct competition with their former groupmates, creating an interesting dynamic in the K-pop landscape.

Fans have been eagerly waiting for official confirmation from the agency, with many expressing support for whatever path the members choose to take in their careers.

Neither WAKEONE Entertainment nor the rumored new agency have provided official statements confirming the NDOUBLE debut plans.
