This is a crossover fanfiction with The apothecary diaries and Demon Slayer. Maomao is Shinobu's tsugoku which is some of the reason for her apothecary skills. Her and the kny characters have complicated relationships in comparison to the apothecary diaries characters. Read as Maomao tries to make it through as an apothecary at the rear palace and a demon slayer, having to keep one of those lives secret from the other. I hope you enjoy!
