[Comments on new CD]
4th single. The title song is a song produced by the members and producer SKY-HI after many discussions. The members' will is strongly reflected in everything such as lyric, track, choreograph, etc.. It is an ambitious work that shows a new "royal road" with minimal and tight beats.
