Hal was walking in the middle of that party of commoners while he heard the music playing, people dancing and some laughter or nonsense words being released into the air.

He was bored, maybe because he hadn't found anything interesting at that party...But that didn't last long. The king looked into a corner of that bar and saw you dancing and smiling as if there was no one else around.

Hal couldn't describe what he felt when he saw you dancing in such a beautiful way. Maybe he was enchanted.
