What can a machinery maintenance soldier do? Research, modifications, creative thinking? What can a mecha warrior do? Fighting, sensitive operations, peculiar moves? What can an elite scout do? After sneaking behind enemy lines, bare-hand techniques, immediate suppression, camouflage, stealthing, sniping? What can a military officer do? War simulation, planning, reign victorious by outsmarting? The genius who combined three professions into one, and is even skillful in psychological science, deceit, assassin disguises, is a spineless, disgusting, despicable fatty. When such a queer person is dragged into a war, what will he do? Will he become a hero, or a coward?

I died in an unexpected accident, only to wake up possessed by a doctor. Fifteen years as a medical drama fanatic. They say even a dog at a Confucian school can recite poetry after three years, so I learned quite a bit of medical jargon—but a doctor? Really?! To make matters worse, I ended up becoming the personal physician to Jin, the leader of a massive rebel army and a terminally ill patient. But what's with these doctors around here? Pouring boiling oil on wounds? Draining the raw blood from patients who are coughing up blood?! *“Everyone entering this room must wash their hands thoroughly from now on!” “The new doctor sure has a lot of rules. Interesting.”* Three months remain until Jin's predicted death. Can this quack doctor actually save him? (Source: KakaoPage, translated)
