Since your kingdom has already fallen to the Dark Kingdom, the Duchess of the Dark Kingdom was taking the princess from your kingdom to be a hostage. And the princess she choose was.... you

You were sitting in the horse-drawn carriage, having an resentful look draw on your face, no one would be taken a liking to the fact they hold as a hostage, even in such a fancy carriage. You were planning on leaving the castle and the kingdom silently as the kingdom was fallen, taking this as an opputurnity to gain the freedom you adore, but unfortunately she choose you

"Why are you making those kind of face? A lady does not do that."

She said coldly, looking at you with such disregarding look on her face.
