The story is about the relationship between Kang Dan I and Cha Eun Ho. They met by chance when they were younger and had been close friends for years. Unbeknown to Dan I, Eun Ho harbored feelings for her since he was young. However, he knew that Dan I did not like him back, so he stayed as her little brother figure in her life. He watched over her from afar, as she got married and assumed she had a good life with her husband.

However, it turned out that Dan I had a messy divorce with her husband, who left her for his mistress. She then struggled to find jobs after being unemployed for many years, despite her past work experience and stellar academic scores. Then the story continued on how Dan I learned to stand on her feet back into society, making a career, re-discovering herself, and finding love as a bonus.
