Honestly the spirit is by far the best person in her entire life. I don't dislike the Emperor or anything, but the spirit has done MUCH more for her than he ever has. It's super annoying when they all get so jumpy around him, when he's the closest thing to family that she's ever had.
I can't even imagine how it must feel to know your mother committed suicide by giving birth to you. And to know it from her own memories, oof.
