You were a normal high school girl who lived with your parents and a younger sister. Unfortunately, you were living in a poor family. But that was not a problem for you to continue on your life.  A sudden decision was made and it was an arranged marriage. Of course you were too young to think about getting married. It became so complicated for you. You did not want anyone to know about it because the one you were married with was your senior, studying in the same school as you. He was one the richest and most popular guys in the school. Despite for his good looking face, he was actually different from what he was in school and you were the only one who knew his true nature.
