Opal eventually 'lock herself up' in the attic as a sort of passive-aggressive answer to his 'don't ever meet Stella' demand.
Guy decide to leave her alone, thinking she'll eventually come out and apologize for the things she said.
Then while reading various kind of books, she seem to have found some kind of embezzlement? within the duke's family record.
So she plan to return home to have one of her servant who's a pro in this field look into it.
So she went to talk to him about going home for a bit.
The guy was expecting her to apologize for saying mean things to his servant/waifu, so insert surprised pikachu face here.
(He seem to have remembered her as being the meek type when they first met and danced 3 years ago, though not sure how this relate into all this)
On her way out, Stella was there waiting in the hallway, then she started raging about how she should've been the legal wife and all that.
So the noise obviously made the guy come out, immediately side with the bitch despite Opal trying to say she didn't do anything to her, and told Opal to just piss off already if she's leaving.
So she returned home, and everyone is nice to her because nobody here believe in those false rumors.
The coachman, Cave, also got treated nicely and is starting to go "wao, she's totally nothing like the rumors I've heard"
For example, when they were leaving, Cave asked the other servants to thank the chefs for especially preparing nice meal for him, but the servants clarify those were the usual for them, and it was Opal herself who improved their food condition.
The servant who she asked to investigate even mentioned that if the truth of how Opal's been treated (she hid it from them) came out, pretty much all the servants and the citizens of the fief will likely storm that douche's place, even he himself is pretty angry at them but is holding it.
So for now, the answer is neither.
