The group teaser shows all the members smiling brightly for the camera. Compared to their first group teaser image that was revealed a few days ago in which they were seen dressed in all black, this one seems to be a bit lighter and shows their bright personalities more. They are also seen wearing very similar outfits to one another to meet their concept as a team. 

Check out the group photo below!
