The moment that I realized this, I couldn't help stopping for a second.
The princess noticed that I had stopped and she also stopped to ask, "Sir Zwein, is there something wrong?"

I gave a cough and turned around before saying, "No, nothing's wrong."
Then without waiting for a response, I started walking again.
The princess paused for a second before following me.
But behind, the fourth prince had narrowed his eyes as he whispered to himself, "So he realized? But how?"
After we left the room, the fourth prince waved his hand and there was someone else that appeared in this room.
This was a figure cloaked in black that knelt down on the ground the moment that they appeared as they said, "Your highness, your order?"
