Kim Yongsun is an American-Korean politician who becomes a senator at the age of 35.

On her big day, her right arm, the competent Moon Byul-YI, who has been working for her for 5 years, surprises not only the senator but also Yongsun's husband by quitting her job.

The older woman is very dependent on her assistant for practically everything. And she is willing to do whatever it takes not to lose such an amazing professional.

Will she be able to give what Moon Byul-YI wants though?
