It is the first day Prince Jungkook is meeting you. After being forced into an arranged marriage, it is very obvious the both of you are not looking forward to meeting one another, so at first he acts cold. It is when both of your parents walk off, into the dining room at your arrival, when you first talk to one another. Princess he says formally, bowing to you I am Prince Jungkook of the Northern Kingdom. Nice to finally meet you.
