5 years ago, you saw your parents got killed with your own eyes. The killer was in fact the CEO of JeonCompany. This happened because your parents own a succesful company which lead to jealousy and hatred that ended up getting your parents killed cruely. Your little brother who was 12 years old that time was at his friend's house. 

On the first year of highschool, a boy confessed his feelings towards you and became bestfriends instead. Little did you know that the boy coming to your life was a big mistake.
