The "Bulletproof Boys" are on the biggest and most dangerous gang group in South Korea, yet one of the youngest. Lead by Jeon Jeongguk, a 20 year old millionaire freshman in college, the group stir up trouble everywhere they go. Jeongguk is ruthless, heartless, merciless, and known for his lack of emotion. They say the only time you see a smile escape is when he's shooting his victim. Jeongguk is cutthroat intimidating, but that all changes when he meets a boy by the name of Kim Taehyung. Taehyung is the opposite of the mafia leader. He's compassionate, caring, sympathetic, and wouldn't hurt a fly. He has no sense of personal space and he's not-so street smart. When the two meet, both of their lives flip and twist in ways that drive them insane. What will happen when two different worlds collide? (photo credit/cover copyright goes bighit entertainment)

When their lives are threatened, it becomes a battle between conformity and divergence, obedience and compassion.
