Before becoming the international phenomenon of Anime and light novels that mix medicine, poisons and imperial politics. Kusuriya no Hitorigoto (d)The Apothecary Diaries) had a radically different approach. In a recent interview for NHK World-Japan, its author, Natsu Hyuuga, revealed that the initial concept of the story was much more earthly and dramatic. Maomao was a mother of three and Jinshi was destined to die in the first chapters. The revelation surprised fans and offers a fascinating insight into how the works evolve in response to their readers and the publishing environment.
The drastic changes that transformed The Apothecary Diaries

During his intervention in the program, Hyuuga shared that the first incarnation of The Apothecary Diaries It emerged as a hobby project during her time as a fan writer. The story was set in a mining town contaminated by toxins, where Maomao. A housewife with three children used her medical knowledge to solve cases of poisoning that affected the children of a wealthy family.
At first, the main character was a mother with three children. He worked for a rich family whose children died from mining toxins. That’s where it started. Hyuuga explained.
This more realistic approach focused on a marginal social environment reflected the environmental and labor concerns of mining communities. But it failed to attract the attention of readers of light novels, who tended to prefer scenarios with more fantastic or historical overtones.
I set it in the city to make it more striking. A city full of poisons is scary. But where there is power, there is poison. The author recounted, detailing how the change of environment allowed her to introduce more attractive visual and narrative elements.
It was like that Hyuuga completely reconfigured the world of the history of The Apothecary Diaries. transferring her to the palace of a fictional empire. This new scenario gave him space to develop a more sophisticated narrative, with conspiracies, imperial hierarchies, concubines, and internal conflicts disguised as medical cases.
The original concept of the work

Another drastic change was the role of Jinshi, who initially was not meant to last long. Jinshi was going to die at the hands of Gaoshun and Maomao would be the mother of three children. Hyuuga Natsu reveals the dark original concept of The Apothecary Diaries, very different from the current one.
Jinshi didn’t have much weight, and Gaoshun was there to keep an eye on him. I thought of a plot where Gaoshun is ordered to kill Jinshi.
However, the relationship between Maomao and Jinshi It quickly became one of the most beloved pillars in history. Readers connected with their unique relationship. she, cynical and rational; He, enigmatic and charming. Jinshi’s unexpected charisma and his chemistry with the protagonist convinced Hyuuga that it should stay, and even occupy a central role in the development of the plot.
Normally I do not change the main frame. I only make minor adjustments when necessary. There is no need to write things that readers do not enjoy. The author affirmed, making her focus clear on the feedback from her audience.
The Apothecary Diaries (Original title Kusuriya no Hitorigoto) began in 2011 as an amateur novel published on the site Shousetsuka or Narou. The following year it was acquired by the publisher SHUFUNOTOMO, and in 2014 it was published as a series of light novels with illustrations of Touko Shino.

These revelations show how The Apothecary Diaries It could have been a completely different story.

The Maomao That today we know has no children or lives among fireplaces, but its essence Curiosity, ingenuity and the fight against poison in all its forms is as alive as from the first draft.
