When Cinderella's story turned upside down.

Yun Lee is a daughter of one of the top businessmen in Korea but unlike other rich kids, she was kind and humble. When their housekeeper got divorced to her husband, her son, Luhan, was forced to live in the house where hid she worked which was Yun Lee's house. Luhan was a smart and handsome guy. Everything changes when the two started to fall for each other but both kept their feelings inside and denied them. When Luhan was adopted by a rich family who were close to Yun Lee's parents, who can not bear a child, he started giving up on Yun Lee knowing that nothing would happen to them. To help him move on, he got stuck with Shin Hya. A girl who was inlove to him even before he got to Seoul. As time passed by, Luhan's adoptive parents decided that he may know the girl they wanted him to marry to. But Luhan, who was fighting for Shin Hya avoided his parents everytime they open up the topic of him getting married.
Yun Lee, on the other hand who was still inlove to Luhan, knew that she was arranged to be married to him. So she stalked Luhan and found him fighting for someone else.
How hard is it seeing someone you love fighting for someone else? Is there gonna be a happy ever after for the both of them? ;)
