7 boys attend a wealthy, high-class school. Each of them come from a prosperous family and represent as royal figures to the whole city. However, this city wasn't all that simple and cultivated as you thought.
On the outskirts of town, renegade groups barge in every night holding their guns and terrorize the town-spray painting brick walls in the alleyways, setting fire to people's lawns, exploding fireworks in the streets, and even rob banks and houses.
In order to put all of the chaos to rest, the boys decided to confidentially turn against their elegant-mannered life and create an undercover rebel gang, 방탄소년단 (Bulletproof Boy Scouts).
