She was the princess

Sebastian looked at Nathaniel.

As the vampire king, he obviously knew who this person was. 

He remembered Elliana whimpering Nathaniel's name in her sleep. Does that mean she was talking about the to-be Dark Witch-king? What was her relationship with him? 

The way he was holding her so intimately in his arms as if he was afraid that he would accidentally hurt her made Sebastian grit his teeth.

Wasn't this too much? 

Nathaniel looked into the eyes of the man with whom he worked so many times in the past to take down all the enemies around them.

The sense of familiarity in his eyes, all because of his rank and not because they knew each other before that, made Nathaniel sigh.

It was probably a good thing that Elliana lost her memories. She would've died again if she had to go through this all alone.
