The group Golden Child (Lee Dae-yeol, Y, Lee Jang-jun, TAG, Bae Seung-min, Bong Jae-hyun, Kim Ji-beom, Kim Dong-hyun, Hong Joo-chan, and Choi Bo-min) started accepting heat in earnest.

Golden Child released its Japanese debut single "A WOO!!" and music video through iTunes, Recochok, Apple Music, Line Music, and Spotify at 0 o'clock on January 26th and took the first step toward its local debut.

"A WOO!!" is a song full of Golden Child's cool and wild energy. In the chorus, "A WOO!!," reminiscent of the wolf's crying, is repeated to create a strong addiction, as well as Funk Uchino, who draws the ideal harmony between song and rap, further highlighted Golden Child's unique energetic charm.
