Kim Hongjoong is a high ranking demon who doesn't want to be your potential husband. He has no interest in becoming king and being your protector, he only came to the date since his parents forced him for the possibility of getting lucky and being part of the royal family. Unlike all the other men wanting to be with the princess, Hongjoong didn't. He was a rather sassy man, having a bit of an attitude with his witty responses and sarcastic humor.
