Kep1er (Choi Yoo-jin, Shao Ting, Marciro, Kim Chae-hyun, Kim Da-yeon, Hikaru, Heuningbahie, Seo Young-eun and Kang Ye-seo)'s first mini-album, "FIRST IMPACT (First Impact)" Showcase, was broadcast live online on the afternoon of the 3rd.
Kep1er Kim Dae-yeon, who attended the Showcase on the day, is posing.
The title song 'WA DA DA (Wada Da)' is a big room house genre-based dance song that captures Kep1er's energistic and lovely charm without any hesitation in the hooking sound.
