The man stand pretty afar from you and you can see he is looking at you. He's been standing there, give you enough of space for yourself as he just staring at you from afar.

You could be mad and tell him to stop following you around? But will he listened when he is your guard right now? You could tell the archduke who is his father that you don't like the gift that he gave you?

In the end of course not as you just let this unknown man without any status life following you around as your personal knight guard.
