Bae Joohyun is the CEO of Goddess fashion line, a thriving independent company originated in South Korea that is beggining to enter the international market, rivaling Gucci, Balenciaga, Versace and Saint Laurent to name.

She is strict, straight forward and very competitive. 

Kang Seulgi is the secretary of Bae Joohyun for almost four years.

She is very efficient, clever and hard working. 

Secretary Kang learned by heart CEO Bae's schedule and familiarized her boss' likes and dislikes, and preferences, not a single day at work has she made a mistake; a flawless all-kill record. 

Bae Joohyun never had a headache because of Secretary Kang; all paper works that need to be sorted out and signed are always in complete order and perfectly stacked in her table, meetings are scheduled that never they have overlapped with one another, and all clients sign and seal contracts with her company, all thanks to Secretary Kang.

They work harmoniously together like a well-oiled machine. 

So when CEO Bae received a resignation letter from Kang Seulgi, she is more than surprised.

'What is wrong with Secretary Kang?'
