She is a strong and proud individual that wouldn't step aside for anyone and has found an inner peace among what she felt used to be a place where there was chaos and she was alone. She still is a loner type when it comes to dealing with personal problems, but this time, she chooses to be this way because she knows she can overcome them herself. She may be someone who easily picks up on the emotions of those around her but only reaches out during times of dire need. Very independent, but sets morally high standards for herself and those she would call her friends.
Others might see him as scary at first, but he is very kind to those who get to know him better. He has an eye for detail and is content both with standing out a little and blending in. He is creative and intelligent. He is also usually calm, but may have a bad temper when angered.
She may prefer more often than not time alone with interests. Those interests may be few, but well developed in knowledge and understanding. She may appear distant though is quite altruistic and considerate.
He is a very quiet and thoughtful individual. His focus is internal, and is usually very in tune with his surroundings. He is the quiet observer, and a keen learner, but only in areas that he has a strong interest in.
She likes cute things, she probably reads fantasy books, is visual enough to make a well balanced avatar, but her style is somewhat simplistic and elegantly minimalist (but cute minimalist). She has a good aesthetic. She probably likes Spring and flowers.
(I'm going with 'her' for now. I hope you don't mind. Do you have a preferred pronoun?)
