The group will be debuting this April 9 at 12 PM KST with their 1st mini album, 'Twenty's Noir'. Their title track is "Gangsta", and their first set of teasers include a teaser video of Yang Si Ha (above), plus an individual teaser photo of Nam Yun Sung (below).
In the above video teaser, a female lead appears in front of a well-dressed doorman, Yang Si Ha. He takes her invitation, opens it, and lets her inside.
Stay tuned for more of Noir's debut teasers coming soon.
