I smell trouble brewing... Chiefly in the form of Zenjirou proposing to marry a northerner (most likely Lady Victoria, the spear woman we just saw) in order to deepen the political relations with the Northern Kingdom.
He'll be doing it for the good of his wife's country, but she can't help but feel jealous.
But what can I say, the mangaka clearly has a type... Tall, big-breasted, broad-shouldered women with a sense of authority. And I'd be lying if I said that wasn't also my type.
