“...If he doesn't receive guiding, that child will die.” The war hero and S-class guide Kang Ha-Jung, whose body is covered in scars. His plans for his long-awaited retirement go down the drain, and to make matters worse, he becomes the guide of the much younger Kim Mu-Hyeok. One day, while on a mission, he is killed by an unidentified esper. As he laments not retiring before his death, he wakes up to find himself in the body of a complete stranger, and even more surprisingly, in the body of a D-rank guide who shares his name… “Now that it’s come to this, I’m going to retire before anyone finds out.”

Worse yet, a sudden ambush cuts his life tragically short… or does it? Waking up in the hospital years later, he finds himself in the body of Sergeant Kang, a different person who happens to share the same name. But that’s not the only mystery to be solved. Strange things are happening at the Esper/Guide center, and his old partner, Kim Muhyeok, still needs his help…
