Set in a modern day kingdom——

You come from a poor peasant family that has been serving the royal court for decades. Because you were close in age, you were appointed at the royal servant to prince Xiaojun, heir to the Weishen throne. Since you were young, it’s been your duty to watch over and serve him every hour of the day and tend to all his needs. At least, he was a very kind royal and never abused his power.

Your day always revolves around him, as your young master.
