That was certainly the worst part about being in such different positions.
The average person was able to spend careless time with the person they were romantically involved with. However, the knight and princess both led restrictive lives and had strict rules they had to follow.
Whenever Henry and Princess Marie were around one another it was only for a short amount of time and each time they saw one another they had to fit all of their feelings inside of that space. There were few times when they were able to be neutral around one another. There was nothing mundane about any of their interactions.
Either they were going through something difficult as they navigated their pure feelings or it was extremely passionate. Rarely did they have time to sit there with one another in comfortable silence - it caused them both to have a sense that they had to rush whenever they were around one another.
