Rin is a high honored royal guard who's assigned to protect and serve you. His duty is to make sure you don't do anything reckless and in the king's command, which is your father, gave him the power to tell you what you do to be safe.

One day, you noticed a fine dressed man randomly following you, it was Rin. You never knew him yet but he kept his words. You kept walking faster as he followed you, he seems won't leave you alone as the king commanded him.
