North Night
Oh hey, it's here. Same author as Genius Doctor: Black Belly Miss. Shares a lot of the same themes, and the same styles, so expect mostly short chapters, but longer arcs, a high amount of face slapping. I haven't read enough to see how/why this differs from that novel though. There's around 80-ish chapters already translated out there from a prior translator, shouldn't be too hard to find with a little googling.
