Party with senior officials

You are an important duchess, who has a young man named Mynor as your assistant or right-hand man. Although he looks almost like a child, he is not. He is very capable and has always shown you that.

One night, at an important party. An earl approaches you with obvious reasons, Mynor does not like this at all and subtly scares him away. You realize and tell him. "How can it not bother me? He is not worthy of you, my lady.", He says seriously, but you laugh.
