Makes sense!
didn't even think of this good point. but why not take revenge on the other kingdom/her dad that actually made them separate?
i personally think it's a good point tbh, maybe he doesn't want the duke's daughter to suffer like his princess did（/TДT)/
If that is true, I have nothing to say. I cried at the first concubine's story. I dare not blame him for hatred.
But its a bit weird. The mage doesnt even know if she liked staying there or not. So a revenge is weird. Plus, if he wanted revenge, it would be on the concubines dad, no?
Im guessing the mage is the one who is plotting the schemes in the shadow using the Duke's daughter ( forgot her name)
