I agree, she's not thinking things through properly.
If she is the only woman whom he can touch, no way in *bleep* is he letting her go after the "sham engagement" ends.
He's at least attempting to be semi-decent about it, but his aides... well, they don't seem to want to take any chances, not realizing that they really don't want to scare her off by being too high-handed.
I mean, if she really is the only female he can touch, unless you want to enslave her she does have room to maneuver and significant bargaining power, so don't go getting her back up, yes?
And... yes, somehow magic has to tie into all of this. Because the premise won't work otherwise.
