The album was announced by the group's Korean agency, WM Entertainment, with details of the album release and along with a release of the group's first DVD B1A4 History 2011-2012 in Japan. The album was released in three different editions: a CD+DVD, including the CD and a DVD including the music videos of "Beautiful Target" and "Oyasumi Good Night", as well its making-of videos, a CD+Goods, including the CD and a special member figure (one out of five different types) and a regular edition, including the CD itself and a special trading card (one out of five different types). All editions came with a special lottery ticket to a Premium Event of their first Japanese album.[2]
The album is composed of ten songs: two singles, five new songs, and three Japanese versions of songs previously recorded in Korean. The tracks "O.K", "Only One" and "Waruikoto Bakari Manande" were originally recorded in Korean and released on the group's debut mini album Let's Fly.[3]
