THIS this is what I've been looking for!!!! Imo In lots of story the concept of unwavering hero and plain white character in front of evil and harsh reality make no sense like you gotta dirty yourself in order to end the dirty system itself especially if you don't have power! The Mc character, sacrifice,  and plan on correcting the system and dragging the evil down with their sins make it even more thrilling!
Ngl I would love to see a fixed ending but this open ending isn't so bad either.                                    
I mean, didn't she already said multiple times that she's worked like a slave by the princess? Why did the ml misunderstand her as a powerful person controlling in the background?
                                                I mean, think frm his pov, she is a very intelligent human she handles most of the kingdom's stuff and is clever enough to even challange ml. And then she says she was a slave and that she's not remia. Even I think with her capabilities she couldve easily overthrow salt, but as you see she has always been suppressed so fl doey actually know that her capabilities are enough to easily skyrocket her life. 
Tho it's still ml's fault to not check fl background properly. If he did a lil more digging he couldve found that she was exploited                                            

		








Hmmm I feel the plot is kinda lacking, like something is not there
