both are bmsg audition shows and the process of group formation is relatively similar. i personally think bmsg shows are some of the best audition shows as they truly work towards improving the skills of participants and choosing the ones most fitting to debut in the end.
Both series are audition programs that follow the formation of a boy group under BMSG. Throughout the course of the show you see multiple performances of original songs and the development of the skills of the trainees.
The First is the first ever audition show from BMSG, where we first meet Taiki and Rui - it shows not only important context for Rui and Taiki's story, but also context of BMSG as a whole and the ideals behind the company's core existence.
