Okay, what you see is what you get. She's definitely a young girl whom may or may not had a rough past judging by the fact that you had to die to become an angel along with the fact that she's had nearly six-hundred years under her belt of having to deal with stuff concerning the moral compass of the world not to mention having to do that when unable to speak and in a tiny-body no less. People don't really take you seriously when you have one of those traits let alone both. Friends and enemies, she doesn't have them as she tries to keep a unbiased view of things as it's part of her job. Even if you disrespect her and beat her up (though it's doubtful you can ;;;;;3) she'll still harbor zero hate towards a person. This is why attempting to get her to fall in-love with you is near impossible unless if you find and tug at all of those weak spots, even a six hundred year old age has things that she doesn't know about and interests her although she may attempt to hide it but when that blank face makes a smile you know you're on the right track.
