The prince is always jealous of her. The king would always compare the prince to aristia. He misunderstood the kings action because he didnt received any love when he was younger because he is the sole heir and should not be emotionally weak.. The king always love the prince but he just cant express it for he is the crown prince. He hated aristia more when aristia acted indifferent towards him. The prince would always hurt aristia because he wants to see the (broken,imperfect,the expression in her eye) but the prince failed because aristia would always tolerate it and doesnt show any emotion.
also the reason he is like that because of the poison he takes that Jieun Recommended that came from Duke Zena/Jena.
A poison that will make a person have dellusions , headaches and sudden anger outburst.
he was also fed drugs soooo his mind was not the clearest.
