Yk what

I feel like we're all forgetting that Erez is literally set to take the Dukes soul to the demon realm when he dies, like Erez is a literal demon so idk how he'd end up with Keira, like if they do they'd be together a few maybe 80 years and dude would be completely alone when she dies, and not to mention Joseph her knight would have to watch the woman he loves marry another man and still have to stick by her side as he's a knight, like dude that's just plain cruel.
If it's supposed to end happily and at least somewhat similar to the novel ending I expect it to be Joseph together with FL traveling with the brother .
And if they try to make a new alternate "romantic" ending with Erez then it'd have to be something like her forming some kind of demonic contract and him taking her soul to the demon realm in place of her father or some shit like that.
Or maybe author might pull some BS where they make two endings one for each ML
