This is not the first time that the band has experienced an illegal leaking of its material. In March, files for “Boomerang” and “Gold,” both on the band’s second EP, “0+1=1 (I Promise You),” were uploaded to the Internet five days ahead of the record’s release.

“We figured out what was going on right after the music file was leaked and took necessary internal measures, including reporting it to the police,” Swing Entertainment, which manages the group, said. “We’re very sorry for that and will deal sternly with those who leaked the file.”

Meanwhile, chances are high the new release will be the popular project band’s final album. The group, which was formed through the 2017 survival competition TV show “Produce 101 Season 2,” is set to disband after their contract expires Dec. 31. (Yonhap)
