What's she gonna do as a 10 year old? Shank him and run the country?
It's being shown that right now she's just surviving and, since she can't let go of her anger toward the Emperor, will likely rebel or work alongside a rebellion to get revenge when she's older. Let her marinate. She's a child that can be killed at any moment for even looking at the princess wrong. And she obviously doesn't want to be friends with the princess, but isn't in any position to refuse.
Loooool, the 'shank him and run the country' caught me sooo off guard I snorted! Loooool
If it were me, I think I'd grab that princess's hair and yank it while shouting 'your father killed mine' and wreck her face out of spite and resentment.
Yeah... offing the emperor is impossible... but she could very well "shank" the princess and go ou in style...
Tho what comes next is for the future me to think about lol
She's trying to do her best to survive bcos thats what her family wanted. That's literally one of the last things they asked of her.
Hrmm low expectations because this mc kinda just airhead and like saints accept everything what other do to her, but leave the princess oblivious about her actions and befriend her , even tho princess father kill mc family ┑(￣Д ￣)┍
