The boys are a project group born from 'Produce 101' season 2. They'll be debuting later today at 6PM KST with title song "Juliette". During their showcase, which was held at noon KST, the boys revealed, "Our official promotions will be about a year. But we want to promote longer if possible for our fans. For us, Rainz was like rain in a drought. It's such a precious chance that we want this not to stop as a short rain, but continue as a monsoon."
This means that Rainz will actually promote for longer than JBJ, whose contract together is only 7 months.
Stay tuned for Rainz's debut later today!
