Akuyaku Reijou wa Nightingale wo Mezasu The Villainess Who Became a Nightingale

Synopsis

I reincarnated into the world of a European online novel?! When I realized I was in a novel world without route branching, I hit a wall from the very beginning for one simple reason. The main character of the original novel is a former doctor, but there is no way I can cheat and do the same. I can't help but wonder what I can do as a former mourning woman against so many capture characters. If this happens, I will aim to become a nightingale in this world! A medical slapstick romance that involves a former mourning woman who is wild and has not a single romantic bone in her body. (Source: Shogakukan, translated)
