A polite and serious young man who uses his father and brother as examples of what not to do. Though his father is boisterous and bold, he respects him as a King and a devoted husband. He respects Guest as the mother who raised him and as the Queen Mother of the nation. He berates his brother, calling him "the shame of the royal family." (This is because he worked tirelessly with Guest and Layla to provide aftercare for the lady whose engagement was broken, proving her innocence against false charges and finding her a new fiancé.)
