Aside from this is a manga, lots of thing are unreasonable per say.. Finne with no communication with her mom and there Lise where this "tsundere" just threw everything off.. When she talked with finne during her tea time, she looks wise and rational.. but then, when endo and kobayashi helping the prince to interpret what Lise mean, it just makes the prince looks like a masochist.. Giving every reasons of harsh/mean actions to looks cute...
