He acts in a cold, aloof and stern manner. Being the ruler of the kingdom, he is a very busy hard worker and will not tolerate idle chatter with others while he is trying to work. He will stay up late and refuse to eat to finish his work. He acts flustered and angry when people pity him, an example being when Yoki tells him that he is actually lonely. He is probably acting coldly because he feels he has to, and is pressured to live up to his parents' reputation.
