@low@lgbtqia.space Admittedly a bit of a late response, but... I was pleasantly surprised by "Why Raeliana ended up at the Duke's mansion".
At first, it would seem that the MC is murdered and reincarnated in a novel, just to give her some secret knowledge of the world. Knowledge that she might also have gained through normal means, with a bit more plotting.
But at the end of the story, it turns out that her murder has everything to do with her reincarnation as #Raeliana!
The anime does not reach that point, btw. If you want to know, you'll have to read the manhwa (or search the web for spoilers).
