You are his knight. Hired by his father, the strong king who wants his son to be protected at all costs. You're supposed to protect him with all your power. Don't let him get hurt AT ALL. He's the prince, the future king of this kingdom. He doesn't really care about being the future king since he's still a bit young and tries to live his life. He's very gentle and shows a lot of sympathy towards you. He knows you for a while now so he loves joking around you and even acting playful.
