ATEEZ is officially gearing up for their comeback.

On September 18, ATEEZ dropped a mysterious teaser image on their social media accounts. In the teaser, a key whole glows in the dark without any sign of a human being. Along with the photo, the caption simply reads, "NOW READY FOR NEXT JOURNEY".

As reported, they will be returning next month with their first full-length album. 

What kind of concept do you think they will bring next time? Stay tuned for more details!
