Society tends to judge you by the way you look, by the way you dress and your family backgrounds. Unfortunately for seohyun she will always be judge by her family backgrounds. Many fear the Kwon family aka the dragon family and they will never dare to go against them. It is a family that is look as PERFECT. Every kid in the Kwon family comes from very prestigious bloodline except for seohyun. She has always been look low by some of the Kwon family member due to the fact that she is not a full blood.  You may wonder what is a full blood. Well let me explained it to you. In this society there is two kinds of people there is the common people who are pretty much average and there is the Blue blood people who comes from a bloodline full of kings and queens ancestor. But that is not all that distinguish them. For generations the Blue blood people have a sorta special powers. An example will be the Kwon family, they are known as the dragon family since there symbol is the dragon. They are courageous, smart and are able to control the fire. Among the blue blood people, the Kwon family is the most powerful in the fire region that is, there is still more blue blood people that are as fear and prestigious as the Kwon family.
