The king's son, Kai, who was very cold and emotionless, will soon become the next king. The prince was handsome, his black hair was well adjusted, and his black eyes shone like black diamond, he was neatly dressed in royal clothes. He didn't have any friends, and he didn't really want to. Kai's parents were gentle towards his son, but his father was serious about the responsibilities of the kingdom, and obviously his son was also serious, since next year he would become the heir king.
