Just hours after dropping the first clue to their first ever comeback since debut, ATEEZ have now surprised with another sudden teaser image!

Previously, ATEEZ successfully caught fans' attention with their debut album 'Treasure EP.1: All To Zero' and their "hip-hop pirates" concept. Now, the group has unveiled a new teaser image hinting heavily at an all-new transformation, also announcing the release date of their 2nd mini album 'Treasure EP.2: Zero To One' - January 15 at 6 PM KST.

ATEEZ's comeback title track will be called "Say My Name", as you can see the phrase appearing repeatedly in the black and white group teaser photo. Be sure to mark your calendars for the boys' comeback time table, below.
