but in Livia's case, she is prideful and does not like this bullshit.
Well, in Marie's defense, she grew up being spoiled by her onii-chan, and seeing how he acts most of the time, she probably started acting spoiled more just to get those moments of great caring.
She probably also went after men that superficially acted like her brother, and since it looks like Leon mostly showed up his annoyed sides the her, she ended up with those that did not have the caring side that she was looking for.
