On November 14, the full mp3 file of Wanna One's upcoming title track 'Spring Breeze' (literal title) was shared via anonymous chatrooms and various social media platforms.

The agency commented, "It is very unfortunate that the song was leaked prior to its release. We will find the source of the leak and take strong actions."

Back in March, the group's title track 'BOOMERANG' from its second mini album '0+1=1 (I PROMISE YOU)' was leaked five days ahead of its official release.
