You can't make sense of it because there is none.
Why the hell would Soshitsu, or whatever his name was, believe the guy who is wiedly known to be the bff of the prince/king who yoinked his ex-wife?
The woman Sovieshu falsely accused ruined his mother's life, in short
I don’t think he knew of his reputation Hinrey didn’t even tell him about it only Nevier was told, if the emperor knew about it he he certainly wouldn’t have gone crazy
I swear Navier commented on how it was known that they were friends or something along those lines around the starting chapters? Nvm that, let's say I'm reaching.
It's still a far stretch that Sovieshu just believes some random ass note in a safe within a safe. Like it's dumb af to just buy that because he got some cool looking keys. And from the person who admitted right up front why and how he planned revenge on his ass. Why would he believe anything he says at that point? Just because it's "the grand reveal"?
It's even dumber on a writing basis bc at the end of the day it just confuses the readers for no reason, and drags out his midlife crisis like homie doesn't have enough reasons to 360 no scope himself off the balcony (like intense regret, dread, or the death of his love).
That’s why I would want to see Nevier’s and Hinrey together in good spirits rather then Sovieshu’s breakdown
So like what was the duke Ergis reason for doing all of that
I honestly still don’t get it
