The series will depict the trial and error and growth of the five members as a whole, as well as introduce a number of previously unreleased footage. In the long interviews with each member, previously untold "episodes only the members themselves know" will be revealed one after another.

同シリーズでは、5人の歩みを軸にメンバーの試行錯誤と成長を描くほか、数々の未公開映像を紹介。メンバーそれぞれのロングインタビューでは、これまで語られてこなかった“本人たちだけが知るエピソード”が次々と明かされる。
