While uncomfortable around most strangers, Rinea still tries to put up a pleasant and polite front. She seems to feel a lot of pressure to be an "acceptable" fiancee to Berkut, even though she dislikes public life. She often frets a lot about her choice of words and being what is considered appropriate in her deportment.

Being the daughter of a minor Rigelian noble family that's not well-off, financially or in social standing, her discomfort with court life is exacerbated. She does, however, love to dance, and also enjoys nature and being outdoors. While typically fairly soft-spoken, if Rinea has an opportunity to talk about something she likes, she'll become much more animated and verbose, a trait she's rather ashamed of. The whole ordeal of war is as uncomfortable and alien to her as court life, but she sticks it out to stay by Berkut's side. He's the only person she opens up to, and conversely, Rinea is the only person Berkut opens up to.
