When a Predator Plays the Pray

Kim Jun has always played the role of the goofy, weak schoolboy, hiding his true identity as the former leader of Shadow Viper—a notorious delinquent gang that once ruled the streets. After leaving that life behind, all he wanted was a peaceful existence.

But when he hears that his twin sister is being bullied, he transfers to her school, only to find himself in the middle of a warzone. The school is overrun by violence, controlled by Big Dragon, a ruthless delinquent gang led by the enigmatic Yi Jun. Students fight for survival, and corruption spreads through every hallway.

At first, Kim Jun tries to keep his head down, making friends with San Ha Kang and Yun Do Park—one genius and one troublemaker with good hearts. But as the chaos escalates, his past instincts refuse to stay buried. When he finally clashes with Yi Jun, he realizes he can no longer remain in the shadows.

Can he protect his sister and friends without revealing his past? Or will the former King of Delinquents be forced to reclaim his throne?
