I didn't think it had anything to do with me that the prince had gone mad. Wait, am I the missing fiancée?

A rumor was spreading throughout the kingdom that the kind-hearted prince had gone mad. It was said that he had lost his mind because his fiancée had died or gone missing under some circumstances. I thought it was a story unrelated to me, since I had been found in a village about a month ago with no memory... "Lady Kikhloe!! Please return to His Highness!!" A knight came claiming that I was apparently that fiancée. I didn't know if it was true, but I decided to meet the prince for now.
