Choi Nam Hee lived a luxurious life as a princess. Kind, caring, graceful, beautiful, everything to describe a princess, she was. But, she never left the palace, never went to a public school, never made many friends except Nari, and never experienced love. 

 

On her 17th birthday, she begs her parents to let her go to a normal school to experience all that she hasn't. Although they were hesitant, they believed she was mature enough to handle the responsibility. But she had to be in disguise for her own safety. Fortunately, since she has never left home, no one has seen her face so all she had to do was to wear regular clothes and stay with her favorite maid/her only friend in her home.

 

Her maid, Moon Nari Sun or Nari for short, was put in charge of watching over the princess since she was actually attending the high school they were sending Nam Hee to. She must watch over her and keep her safe from everyone. Which is a difficult task due to her only being 17, the same age as the princess.

 

Perhaps, during this new experience, Nam Hee will finally be able to experience all that she dreamed of... And maybe even learn what love is...
