After surviving a decade of hell as a child mercenary, all I-Jin Yu wants is a quiet, normal life – a dream that’s about to collide head-on with the brutal reality of Korean high school.

Eight years old, orphaned, and abandoned in a war-torn land, I-Jin was forced to become an elite soldier, living moment-to-moment with death as his constant companion. Now, ten years later, he’s finally returned home to Korea, reunited with the loving family he never knew, including a sister who offers the peace and stability he’s yearned for. But trading bullets for textbooks and battlefields for classrooms proves to be anything but simple. His new "mission" is to blend in, finish high school, and protect his newfound peace, especially from the ruthless bullies who plague his sister and his classmates.

They might think they're tough, but they’re about to learn that I-Jin Yu isn't just another student. He's a walking, breathing arsenal of survival instincts, a master of combat operating under the radar. Can I-Jin navigate the treacherous social minefield of high school without unleashing the warrior within? Or will the 'normal' world be forced to reckon with the lethal skills he’s spent a lifetime honing? Get ready for an explosive drama where a hardened past clashes with a hopeful future, and a quiet teenager holds the power to shatter any threat that dares to disturb his family's peace. This isn't just about surviving high school; it's about claiming the life he fought so hard to find.
