The decision

After leaving Alicia, Harold tried his best to control himself and not smile like an idiot as he walked down the hallway to his chamber. 

More than the kiss, he was a little excited that she wasn't so insistent on running away like before, but rather wanted to know more about him and the Moon kingdom. That had to mean that she was thinking about staying, right?

Why else would she be curious about him and the kingdom, if she was just going to run away the first chance she got?

Harold stopped when he noticed one of the king's guards approaching him, and he raised his eyebrows.

"His Majesty is ready to see you now," the guard informed him with a bow, and Harold followed him.

Earlier, he had waited to meet with the king after welcoming the aristocrats, but the king had been busy attending meetings, so he had returned to stay with Alicia and keep her company instead.
