Why were the princesses proposing to a nobody, that too all of a sudden? Could it be, that it was another one of their strategies to take their opponent by surprise? It was possible, or at least everyone in the room would have thought that.
Ashton was no exception either. At first, he thought their sudden proposal was a way to catch him by surprise. However, with a quick use of [Perception] skill, Ashton was able to determine the truth.
The princesses weren't lying. They were proposing to him with all the correct intentions. They actually wanted to marry him. The situation wasn't something Ashton could have prepared for beforehand... and he wasn't liking it at all.
