The group BOYNEXTDOOR has released the first concept film for their new album.

The video cheerfully captures the six members working their first part-time jobs in various places such as cafes, warehouses, and clothing stores.

The third mini album, '19.99', which will be released on September 9th at 6 PM, is an album that expresses the imperfect number '19.99' as the moment right before turning 20, the hottest age. The title song 'Nice Guy' cheerfully expresses the 'well-founded confidence' of being 19.99 years old and has a popular appeal that anyone can comfortably listen to.
