Synopsis
Yu Ijin was only eight years old when a plane crash in a foreign land left him as the only survivor. Forced to endure alone, he became a dreaded mercenary, developing expertise in combat, hand-to-hand fighting, and marksmanship. A decade later, after encountering soldiers from South Korea, he learns that his family is still alive—his younger sister Dayun and his kindhearted grandfather. Returning to his homeland, Ijin faces the unfamiliar challenge of navigating high school life. He deals with bullying classmates and slowly builds new friendships, but everything feels strange. When his past eventually catches up, he must draw on his hardened survival instincts to defend those he cares about.
