Spoiler
She is not. She loves her sister very much and is very proud of her and wants her to become the next empress
The real botch is the mother. She wants Tiara to become the next Empress and will go to great lengths for that.
There will come a time where pryde will save the kingdom and even the army general or something will side with pryde, but the bitch will still stand still.
Basically almost everyone will see how pryde does her best for the people but the bitch will still hold on to her premonition and not the actual facts.
Later on she will apologize to pryde or something, but if you consider all the suffering that is to come to pryde's , that butch should offer her head instead.
I might have gotten a few things wrong though. Been a few days since I have read the spoiler.
what if Tiara turned out to be a spoiled brat?
what if she was the one creating mischief then blaming it to Pryde?
what if the mother will side with Tiara rather than believing Pryde?
wahhh too many what ifs are running on my mind. i need the next chapters pleaseeeee
