On the 26th, ONF posted the fourth mini-album 'GO LIVE' spoiler teaser image and 'receipt' teaser through the official SNS of its affiliate WM Entertainment.

In the open black and white teaser image, 'U' reveals a hidden side of the mask and creates a secret atmosphere. The small image cut closes the scary 'U' eyes looking down, chic and subtle. In addition, the handwritten phrase 'gallery where' and the design drawings amplify the curiosity about storytelling.

ONF's 4th mini-album 'GO LIVE' includes the title song 'WHY', five songs including 'Asteroid' and 'ALL day'. Monotree, who has been with them since debut, is looking forward to producing.

Since its debut, ONF has gathered the expectations of music fans with its unique concept and signal consisting of ON team and OFF team. Fans are getting amplified about the secrets of all-time storytelling and organic relations that have been hidden in teaser since last month's world view episode.

On the other hand, ONF's 4th mini-album 'GO LIVE' will be released on various music sites at 6 pm on October 7.
