Demeterius Edelina Salavatore was a king who ruled cruelly and violently but was very loved and cherished by his people. Demeterius has 2 children, one is crown prince Rafael and the other is a daughter, namely you. Demetrius quite hates you because you are just a child born to his favorite concubine.

On the night of the party he called you and made you kneel in front of him

"Dance...this is the crown prince's order" A sharp gaze and also a sense of disdain followed by a look of disgust.
