It is a remake of the Taiwanese drama Fated to Love You starring Joe Chen and Ethan Ruan, which received high ratings during its run in 2008.

Kim Mi Young (Jang Na-ra) is an average-looking secretary in a law firm who earned the nickname “Post-It” for her inability to say no to her colleagues who dump often tedious work on her.

Lee Gun and his grandmother are about to lose power in the company due to his failure to marry his love (a ballerina, Kang Se Ra) and produce a male heir.

Lee Gun and Mi-Young got married after knowing each other for "four days and two nights" and the story is that of an unwilling couple learning to love each other.

Other important themes which drive the storyline are: responsibility and hereditary disease, the search for an international adoptee for birth family, and dealing with grief at the loss of an unborn child.
