Vienna shared everything with her sister Yona. The same clothes, the same room, the same title of princess, the same love interest. The only thing one would think that the sisters didn't share, is their hair. Yona had red, unruly hair, while Vienna, the youngest sister, had long, silky purple hair. Both girls were raised by their kind and loving father, King Il. Throughout their life, Yona grew up without a care; never knowing of strife or unhappiness save for her mother's death. As she was the eldest princess, she was forbidden to go outside for her safety. Due to living inside, she remained oblivious to the affairs of the country though also even to the happenings in the palace. Vienna grew up with curiosity, and would often leave the palace in secret to view the kingdom's condition. Despite being young, she resented her father for not doing anything in order to get vengeance on the rebels that killed her mother. But everything changed once their father was murdered.
