Synopsis

A man is struggling with debt after his business as a Korean doctor fails. He finds himself suddenly transmigrated into a fantasy novel as a bedridden crown prince, Ramiel, who is destined to die young. He remembers that his character receives the best medical treatment but still fails, so he decides to take matters into his own hands, using his knowledge as a doctor to find a way to survive. He starts by having his servant collect needles to experiment on his acupoints, starting with the lung meridian, while insisting that it's necessary and promising his servant that he knows what he's doing.
