In a new set of 'Nice' version concept photos unveiled on August 22 KST, BOYNEXTDOOR represented the spirit of today's youth. 

In the teaser images, the BOYNEXTDOOR members each depicted pictures of today's youth just before they turn of legal age at 20, entering the working class for the first time through their first part-time job. Switching from expressions like boredom to mischief, BOYNEXTDOOR perfectly captured the courageous and unpredictable spirits of young people at the age of 19.99, the age of freedom and possibilities. 

Next week from August 24-25, BOYNEXTDOOR plan to drop a series of teaser images hinting at the concept of their pre-release track, "Dangerous", which will be released on September 2. 

Meanwhile, the group's 3rd mini album comeback is scheduled for September 6 at 6 PM KST.
