Ah yes, the east vs west view of relationships. We westerners encourage carnivorous women while east embraces herbivorous women (though carnivore and herbivore are more applied to men over there, but still applies to women). Just another mind boggling aspect one has to learn to get used to when dealing with indecisive main characters and their peers.
Here is an example of characters for something Pixiv Succubus and how characters are mapped with such traits. In this case, there are 2 maps in one here, the one I mentioned above and the other being how sexy or pure a girl is, but also includes their sadistic and masochistic traits. All the illustrations linked into this map gives a pretty good idea of how the stereotypes are applied. You don't even need to know how to read japanese to know how it works. Something of note, when applying the traits; sexy = carnivore, pure = herbivore.
Though I would bet we could see some typical mappings of the HOTD girls based on how they've acted so far. They'd probably fall pretty close to the center, except for the rich girl.
