As an avid Kitsune enjoyer, Kinu represents 2 polar opposites when it comes to Kitsune culture. I'll share my personal understanding, so it might be wrong.
Hime embraces her legacy and her role, and aspires to be an inspiration for her people. She took her mother's lessons to heart, and seeing as Kiyoko has been sealed for 200+ years, Hime acts like a classical oriental princess. Her choice in spouse, Nakano, I believe also comes from those 200 years lost by Kiyoko. Nakano wants to be the quintessential Samurai, versed in sword and poetry, and Hime believes that to be a noble goal. Nakano being an asshole to us is irrelevant to their relationship, but people just love to hate him.
Inari, meanwhile, is of the opinion that traditional royalty behaviour is completely unnecessary for their current situation. People need food more than culture. Everything Kiyoko told her is disconnected from current times, and Kinu will rebel. Her choice in spouse, Hitoshi, represents the exact opposite of royalty life. Hitoshi is quiet, hard-working, and never shows false emotions to better connect with people.
Again, this is my personal understanding, so it may be inaccurate to the real thing. I believe Kinu's content to be well aligned with the choices made during her childhood. And if you found yourself leaning heavily to one side, you probably will enjoy the result. I recommend reading and understanding those choices, to better appreciate how they made Kinu who she is.
