After getting caught smoking at her country school yet again, Nan Hui was sent to live with her mother and unpleasant grandmother in the city. There, she bravely rescued Gong Myeong from a group of violent boys, only to be met with his ingratitude. Angrily stomping on his arm, she never expected to cross paths with him again.
However, Gong Myeong soon approached Nan Hui, desperate for a solution to his heartbreak over a lost love to his own half-brother, Baek Jae Ha.
"Let's enter into a contract relationship. We don't have to love each other, but we can help each other get what we want," he proposed.
With this, the handsome but troubled Cha Gong Myeong and the rebellious Lee Nan Hui became the talk of the town as a faux couple.
But things only become more complicated when Nan Hui's best friend comes to Seoul, bearing feelings for her, and when Gong Myeong's own half-brother begins to fall for her as well.
Can this bad boy prove himself worthy of his own Cinderella, helping her find her glass slipper? Or will their clashing personalities prove to be too much to handle for any romance to ensue?
