Like his family, he's a live-in servant for the king and his family. His job was assigned to be Nani's caretaker. He's only a few months older than her. He acts like he hates her, but is secretly in love. When they were both children, he told her that he loved her. He's sensitive, and a bit of a loner, at times.
