Yeah it’s really hard to tell, cause she could just be really good at acting or she is actually oblivious to everything. I hope she’s acting though cause then the story can become so much more engaging and suspenseful as we see the siblings ‘fight’ to help the other
I think if she was just acting it would add more dimension to her character
I think she's stepping back, even in the first chapter it's implied that she views her brother as the sun. Possibly meaning seeing him as the emperor.
Well its confirmed now
Idk if the sister is genuinely not that bright or is pretending so she could step back on being emperor for her brother.
