BOYNEXTDOOR has rolled out more group and individual concept photos.

As announced, the rookie group is ready to make their comeback with the 1st EP, 'WHY...'. In these concept photos titled 'MOODY,' each member becomes one with his atmosphere, embodying autumn vibes with the rain and fields of reeds.

Their new EP will drop on September 4 at 6 PM KST.
