Is it because she is the royal blood? They want to give her the throne? Ghost
Not sure if you have already read the rest, but yes. Not only that, they want to MONOPOLISE the throne for themselves. Shitty assholes. Can you imagine being told to marry your own brother, who even tho is fake, doesn't wipe out the years you have spent looking at him from a brother view.
