Gender bending is in fact somewhat classical, but not in a good way.
You mean gender swapping, gender bending is something else :p But they really aren't, Valerie is the spoiled rich girl who wants to do something else with her life
and has the possibility to do it because she's rich. A real life example is Comtessa de Dia, one of the very few women composers to survive to this day, and she did it because she's a noblewoman with means. A woman who doesn't have that advantage has no other choice, Oleg's wife (Svetlana?) has no choice but to be an innkeeper. I'd argue Valerie's story isn't about her being beautiful, but her having the means to do whatever she wants to. Don't believe everything that comes out of the companions' mouths, or at least take it with a grain of salt, that is just their perspective. Amiri is the strong woman archetype, like the Nordic shield-maidens, and has the skill/brains to outwit the men in her life, much like Scheherazade.
