Some stories you have read one where the prince is like all mean and stubborn. They never take anything serious, they look at the world as they're own personal slave centre.
Well, Prince Ross Shor Lynch, he isn't a prince from birth. He was poor, until his parents passed away, both from cancer. His heart is broken.
When he comes of age, he is told that he is to be trained to become a prince.
To some random other guy, they would have only taken further, but not Ross. He may take his new life seriously, but not to the extent others would have.
