The boys of VERIVERY explored the concept of "who" they are as they gathered in a mysterious art gallery, in preparation for the release of their new single album 'Series 'O' Round 0 : WHO'. 

Previously, VERIVERY raised curiosity by revealing a group teaser image for 'Round 0 : WHO', which featured the seven members standing in a gallery, filled with portraits of each member. In their latest set of individual teaser cuts, the VERIVERY boys look into the camera as if looking into themselves, reflecting on questions of identity. 

Meanwhile, 'Series 'O' Round 0 : WHO' will serve as a prequel to VERIVERY's ongoing 'Series 'O'' project, which began last year with 'Series 'O' [Round 1 : HALL]' and continued with 'Series 'O' [Round 2 : HOLE]'. 

'Series 'O' Round 0 : WHO' will be out on March 23 at 6 PM KST.
