The Mystical Princess

Disclaimer:
This is actually a manga called Reimei No Arcana. The story IS NOT original. I am just making it into a book to try to interest more people in manga. All credits go to the creators of this manga.
Plot:
The world is cruel. Unfair. Judging people by their hair colour. People with black hair are royalty while the rest are pheasants. Among them, are sub-people. Sub-people are part human part animal and are born with keener senses. They are all seen as lower than humans.
Nakaba is a princess, but her mother was royalty and married a sub-person. Nakaba had with red hair and was looked down upon. She survived thanks to her attendant sub-person whom cared for her, Loki.
She thought that her life was meaningless. Even if she died, the only thing that would change was where she died. One day, to form a peace treaty between her country, Senan, and the neighboring country, Belquat, she is offered as a sacrificial goat in marriage to their prince.
Could hate turn into acceptance?
