Cha Eun-ho is a successful author and a chief editor at a book publishing company. Kang Dan-i is a mother and former successful advertising copywriter. When Cha Eun-ho was a child, Kang Dan-i saved him from an accident and was injured. Kang Dan-i had Cha Eun-ho help her while she was recuperating in hospital and later on bedrest for one year. By helping her acquire books to read from the library, Cha Eun-ho himself became interested in writing. The two youngsters stayed close friends well into adulthood. However, their friendship was strained after Kang Dan-i started dating a selfish, inconsiderate man. Although he disapproved of her choice in a partner, and she too expressed doubt at times, Kang Dan-i stands by her decision to marry this man.

Now in the present, Cha Eun-ho enlists Kang Dan-i to help him find a housekeeper - but he has no idea Kang Dan-i is the one doing the work and taking payment. Her husband has cheated on her, and she is now divorced and unemployed, but he is also unaware of her living situation and the hardships she is facing as a divorced single mother with a large gap in work experience trying to re-enter the professional world. Eventually Kang Dan-i is no longer able to keep her secrets from him, and Cha Eun-ho lends her a helping hand. Their lives become even more intertwined when Kang Dan-i applies to be a temporary task support worker at his publishing company. Although Cha Eun-ho is initially worried about how she will perform, Kang Dan-i surprises him and other senior executives with her creativity and hard work.

The rest of the series is about the personal and professional challenges they face as they slowly start to realize their true feelings for each other and navigate this next stage of their lives.
