He has an unpleasant holier-than-thou attitude of those who flatter themselves thinking they have it better than others by virtue of their own merits, when it's obviously in great part due to their privileged situation. Dude doesn't even realize how rationally indulgent the emperor is with him, not blaming him for being his father's son, and acts like a pompous prick. Seems he's like his father in his youth, I guess: too self-absorbed and proud to realize when he's being ignorant and inconsiderate to the point of really f**ing things up with other people, right until it blows up in his face. Moreover, he definitely enjoys the feeling of how "enduring the attentions" of the spoiled trash princess makes him look so forebearing and enduring, dignified and desirable, gaining him the attention of the surrounding people along with their sympathy and admiration.
yup exactly. he really is just a reflection of his father
bruh it's always when the FL suddenly drops interest that these men start running after them. he made her stand in the rain, ignored her but secretly enjoyed the attention she was giving him. he liked the idea of someone being attached to him without having to do anything. but now that she's done w him, or feels indifferent, he makes up these scenarios that she's sad or hurt etc by his actions. girl nobody cares about u!! back off.
