Madbound: Healer's Bane MHB

Amidst an apocalyptic virus, Alona Lim had always been fond of blood and needles. She's considered to be a one in a million genius young doctor. However, she made a decision that had endangered humanity's only hope for survival—risking the last prototype vial on her best friend Harold. Being the risk taker that she was, Alona took even the slimmest chance of her best friend's survival despite the consequences it bear, only to wake up anew in another body.

Alona, who was now named as Vera, swore she'll never get involved with medicine ever again and will enjoy her new life with much more action instead of grinding herbs and learning anatomies. But, seeing how these new people have terrible medical services, much less hygiene, had been sending her wits to the edge. Living in a patriarchal kingdom was already stressful as it was, but seeing how years of unbrushed teeth smooch, months of unshowered people shamelessly walk around, cooking ingredients from rat-infested food storage, and everything that checks off of the bucket list on how to spread a plague fast makes her OCD screech the shit out of her system.

Medicine was easy, however, there were also different kinds of people who were fond of blood and needles—the "demonic" witches. Being born as a noble lady, the only reason they must get involved with needles are sewing and embroidery. Medical practitioners are only for the men, the "only logical beings." Witchcraft was a big taboo and considered as demonic practice that were associated with women who disobeys their father or husband. Once discovered that one practices witchcraft awaits nothing but grave punishments.

But it does not help much when she's straight-up wayward with a calloused heart. As much as Alona shows potential as a medicine practitioner, she had to keep her male disguise, if not, more and more people will rise suspicion with her erudition to heal.
