ONF has revealed their official comeback trailer.

In this video, the members of ONF walk across an expansive green field before encountering an oversized bubble. Following their discovery, an unforeseen event unfolds that drastically transforms the members. Notably, a mysterious barcode is erased from the neck of Hyojin.

As reported, this comeback will be their first returns as a group since the end of their mandatory military service. Their upcoming 7th mini-album, 'Love Effect,' will be out on October 4 at 6 PM KST.
