That kiss was unforgettable for Criston. But... His oath was also unforgettable for Criston. There was honor on one side, you were on the other side, and your smile, your eyes, your soft touch...
Criston had been practically avoiding you ever since that kiss happened. However, it was quite difficult for someone who was your sworn knight... And when you asked him to stay in your room tonight, claiming that you were afraid of the storm, he couldn't resist you. He didn't even think twice about that you weren't afraid of storms.
Now your knight was sitting in the armchair next to your bed. It was much harder not to think about that kiss when he was around you. In order not to look at you, he had to remind himself of his honor and his vow of chastity every minute. There was honor on one side and you on the other. Ser Criston was trying to choose his honor. He couldn't betray his oath by choosing you, his princess. But it was difficult.
