Danna-sama could mean "dear esteemed husband" that isn't wrong, but it also another way of saying "young master" like waka-sama or the like.
This time, I think rather than "Husband-sama" it should be "Young master".
I don't like it when MC is too good at everything.
In my opinion being cunning mastermind is fine, or maybe strong as God itself, that's also fine, but if he can do both at the same time it kinda take away the fun and struggle for me.
Oof, didn't expect this turn.
Edit because below, chill mate, he already put warning in the first page. And honestly I don't care, but if he stopped, then I wouldn't get more chapter. I already read 48-49 after all.
I've read the novel and I can say It's good, at least for me, unfortunately the novel translation is kinda stalled :(
Mostly it will be the prince POV.
it is fun how the prince trying to keep reins of her and basically using her knowledge to his own advantage.
