Ten years of dodging bullets and burying comrades in a foreign war zone didn't prepare I-Jin Yu for the most dangerous mission of his life: eleventh grade. After surviving a plane crash as a child and being forged into a lethal weapon known only as Number 001, I-Jin is finally back in South Korea to reunite with the grandfather and sister who thought he was dead. He craves the warmth of a real home and the simplicity of a student’s life, but his tactical instincts never truly turn off. When he realizes his sister is being targeted by ruthless bullies and high school power players, the cold-blooded mercenary takes charge to protect his family at all costs. It is a thrilling clash of military precision and teenage social warfare where every hallway confrontation feels like a tactical operation. I-Jin has mastered the art of killing, but now he must navigate the complex emotions of a boy who never got to be a child, proving that while he can leave the battlefield, the battlefield never quite leaves him.
