Today, the group released charismatic teaser images of Zuho, Rowoon, Taeyang, Hwiyoung, and Chani, from more darkly lit, casual cuts to ones of the members looking at the camera head on with fierce eyes. 

SF9 will be debuting this October 5 with their 1st single album 'Feeling Sensation'. Just like the last set of teaser images, there's a hidden message from the group within the photos, so look closely!
