[Currently on Temporary Hiatus] You were Pairin's twin sister. Both of you were inseparable. One day, Pairin becomes ill and is bedridden for some time, and a client is asking for her personally, so you decide to take her place, pretending to be her for a day. You stay with the client, and he seems to have brought his own tea for you to try out. Little did you know that would be the last thing you'd ever do. Next thing you know you you're in an unfamiliar world in Japan, all seems calm...that is until night falls. Read the Author's Foreword for more context. Got the idea from a Kny x Naruto book and decided to mix my favorite animes, let's see where this goes shall we ^u^ ~{Disclaimer: I do not own any of the og characters from Kimetsu no Yaiba or Apothecary Diaries except for some background characters that are not specifically named within the show or do not appear in the original, all rights go to their respective creators/authors}~

Y/n tok the way of the Apothecary after her family got kicked out from the clans working by her uncle and brother. She lives with maomao and her great grand uncle until one day she and Maomao gets kidnapped and sold to work in the rear palace. Y/n finds it to be not as bad as she thought being back there again, but she meets on someone she was about to forget from her pass.

A moment of danger changes everything. When Jinshi plunges down the waterfall with Maomao at the very last second, their only option is to retreat into a forgotten cave for shelter. The way back is submerged-unreachable for someone who cannot swim. In the tight confines of this hideaway, what has long been hidden comes to light. A secret, buried for years, is revealed-and throws Maomao off balance. Between falling drops and silence, between breaths and unspoken longing, something unfolds that neither of them planned-something that reaches far beyond this single day.

As the emperor grows paranoid in the recent illness that has infected his children, he deigns to replace his full personal guard, the Jinyiwei. As he dictates who is to be his closest protector, one name stands out to him. One that he had not seen in a long time. His sister. Maomao saves the lives of the princess, however her warning is not enough to save the prince. See how she progresses throughout the story with someone new looking out for her. (She replaces Lihaku, and her love interest is Pairin) (OC focused) (Slight AU) (I miss ao3 tagging)

This story is based after the end of season 2 of the anime Apocathery Diaries. I know that is a novel but I prefer to keep it based off the anime. Although the story is original all the images for the chapters do not belong to me. Hope you like it :)

Behind closed doors, far from palace walls and lingering gazes, Maomao and Jinshi finally surrender to the tension they've carried for far too long. Between whispered confessions, tender worship, and laughter shared over stolen honey buns, they let go of fear-and choose each other. This is what the palace never saw. What only love, unmasked and unafraid, can reveal.

"Demons cannot be born. That is an absolute truth.*" Yet when Lady Tamayo stumbles upon the ruins of a massacre, she finds the impossible-a newborn demon, torn from his mother's womb, surrounded by death. Muzan Kibutsuji's cruel experiments have created something unnatural, something that should not exist. But to Tamayo, he is not an experiment. He is a child. Now named Arashi, the boy grows up under Tamayo's protection, hidden from the world that would seek to destroy him. But as he begins to uncover the truth of his origins, he is faced with a terrifying question: Was he meant to exist at all? With Demon Slayers and Muzan's forces closing in, Arashi must carve his own path-one that will decide whether he is a monster... or something more. A tale of demons, family, and the struggle to defy fate begins.

She is a hidden marvel-his secret snowflake-seen by no one else in the empire, known only to the emperor, his most precious, breathtaking treasure." I do not claim ownership of any characters, with the sole exception of the original character (OC) that I created.

What if Mao Mao hadn't returned to the inner palace after the fengming incident, what if Jinshi never came to the officials hiring out the courtesans from verdigris house. 10 years after the dismissal. **sorry guys but I killed of mao mao's adoptive father because I don't think he would of let her..**

A sudden political decision forces Maomao, a clever palace apothecary, into marriage with the mysterious Jinshi. As rumors spread through the inner palace, strange poisonings and hidden conspiracies begin to surface. While solving dangerous mysteries together, their "political marriage" slowly becomes far more complicated than either of them expected.
