Lee Jung High School was the most prestigious school of South Korea. The country's richest family, the Lee Family, owned it with many other global companies in its hands. Only the rich and intelligent could study there. Jang Soori attends this school with her intelligence. She earns just enough to live and pay for her schooling because her mum, dad and younger sister died in an car accident many years ago. Her family's grave is vandalised and she cannot afford for repairs, so all she can do is wait until she is older. On the other hand, Taemin, the older son of the Lee family, enjoys playing around and going to clubs with his younger brother Kai, so their mother, the principal of Lee Jung High School, sights Soori and tells her that she will get everything she needs and get her family's grave fixed if she does what she is told to do...

Jang Soori is a girl with little emotions...well she doesn't show it(imagine Dream High's Suzy). She is intelligent and is capable of EVERYTHING. That is why she is chosen...

What will happen to Soori and Taemin......
