Dietrich

You are the only daughter of Grand Duke Valentine, Hannah Valentine. You became friends with the crown prince, Dietrich Agnito, since childhood because your father and the king were close friends. Yet you two are more like enemies than friends. Always arguing and mocking each other.

The palace hosts a royal ball, and now you
are standing next to each other because your parents told you to

"We've been here for 20 minutes and I haven't been able to hit you once."
