Pre-debut
Preparation for the debut of the group has been three years in the making. About selecting the members for the first group signed under his R.A.I.N company, Rain said, "There were a lot of factors involved in the process of making Ciipher, but when I met these kids, I felt like I could bet it all on them. Not just my time or my skill, but all the things I had and have made. Whether the group has good results or not, I don't think I'll regret the things that I gave to this group. That's how talented and well-mannered they are".
