They said, "We met through 'Produce 101' and our debut was confirmed after a lot of obstacles. We thought a lot about if we could debut, and now that we've debuted, we're looking forward to it but we're also worried. But Rainz is 7 members, and we're going to gather together tightly, never give up, and smile as we run forward."

On what they did after 'Produce 101', they said, "After the end, we felt really empty and missed the trainees that we worked hard with. To fill up the emptiness, we just kept practicing. But now that we've debuted, we look forward to every day to meet our fans."
