When the royal family reached their seats, Young Duke Clementine bring his daughter to the seat next to Prince Lucien. That action made everyone more confused about Lady Dresvil's identity and status. It is their first time seeing a noble lady from a different kingdom who wears a tiara on her head and sitting next to the royal family. And it seems like Lady Dresvil's relationship with the Royal Family is really good since all of them have smiles on their faces while talking to her.
When King Lucas raises his hand to signal that he wants their all attention on him, the nobles quickly stop talking with each other and lower their heads. They are patiently waiting for their king's opening speech. While these nobles are bowing in front of King Lucas, only the Dresvil Family remained standing and quietly staring at the king.
