She always felt like the prince is someone who hates her with all his heart.
Even as children she would always feel his piercing gaze on her. Even when she avoids him on every occasion, he would always find a way to meet with her and make her feel miserable.
Her father is the third son of the duke, as such their estates are far too inconsequential to matter to the crown. Even their meetings have been so brief and fleeting.
But he has always taken a liking to punishing her for things she didn't even do. When they were children and occasions in the castle were held, he would come up to her and whisper that she is behaving like a flirtatious little whore.
Whoever the child she was playing with would then avoid her like a plague from that day. He did take away all her opportunities to have friends, in other words.
