Manga Like Ballangunui Dolpari Uisa

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)
