[UPDATE] The teaser film has now been deleted. 

ATEEZ have unveiled a mysterious teaser film titled "I've Seen It, Will You?". 

Earlier today, the boy group announced their comeback with what is believed to be their first single album, 'Spin Off: From The Witness'. Many fans anticipate that the group will continue where they left off with their dystopian storyline, which most recently kicked off a new chapter with 'The World Ep.1 : Movement' in July, then continued with a Japanese album, 'The World Ep. Paradigm', in November. 

More details on ATEEZ's comeback with 'Spin Off: From The Witness' will be revealed soon, leading up to the album's release on December 30.
