Fr fr, like he admitted he was willing to use her affinity towards him if it meant she would work her best for the soldiers and campaign. He knows the effect his disposition has on others and uses it to his benefit.
At first I was like "Okay he does it to benefit the good of the collective, so shady but morally grey at least". Now he is in his feelings because he started to actually vibe with her and he recognized she vibed him too.
Thing is, if she decides to like someone else he should respectfully move on. Take your L sir, you should have made your move instead of waiting, thinking you would always have access to her.
If she has any intelligence she should know that having an affair, much less one involving such important men would destroy her reputation, not just in high society but as a preitess. If she really wants to be with him she'll have to be honest with the Not-Duke first. Although, even if he is joking, the Prince is pretty dark. Like he was a grey guy before but, he is legit dark.

She will not having any affair lmao, instead this will make her realize that he ain't it.
