“I seem to have been reincarnated into the world of a web novel about a reincarnated girl?! In a world without route branching, I somehow stumbled from the very beginning without realizing it. The original novel’s protagonist was a former doctor, but there’s no way I can take the same actions, and what can I, a former shut-in girl, do among the many capture targets…? There’s no point in worrying. If that’s how it is, then I’ll aim to become a Nightingale in this world!!” This is a story of a reckless and romance-challenged former shut-in girl, weaving a tale of medical chaos and love. Using Nightingale as a foothold, in this work-life romance comedy, she embarks on basic medical care, disaster medicine, and frontline medical care in a world without miracles or magic.
