At the age of 33, Oh Dalja still has no luck with men. However, she is proposed by Shin Sedo, her colleague at work, and begins a romantic relationship that she always dreamed of. But it turns out that he is the player of all players.

The whole company knows that Dalja was dumped by Shin Sedo and her career went down the drain. To restore her damaged reputation, she decides to avenge Shin Sedo and Wi Seonju. To do that, she hires Taebong, the boyfriend-at-hire.

Dalja believes that Eom Gijung is the man of destiny, seeing that he came to her at the greatest timing. She is convinced that he is into her. However, Gijung isn't all too eager and even ignores her career.

Dalja begins to date Gijung, a man too perfect for her. However, she is mistaken as a girl with too much history and their relationship takes a wrong turn.

After discovering that Gijung is a married man, Dalja ends the relationship. But she is hesitant when she sees all the love for the first time in her 33 years of life.

Dalja is caught up in the suicide incident of Gijung and is known by everyone as the home breaker. The company holds a disciplinary committee because of her and she is about to be fired.
