Maroo Entertainment said, "We are presenting a new boy group with the aim of debuting in September. We have confirmed nine members and are in the process of making our debut," he said.

Maroo Entertainment's ambitious boy group is a nine-member group that was born in 2004-1999.

In particular, Lee Woo-jin, Lee Jin-woo and Lee Tae-seung, who made their pre-unit debut with "Tintin" in September last year, were included after playing on Mnet's "Produce X 101."
