The things women sacrifice for love! Shin Na Ra (Han Chae Young) always dreamed of having a successful career but she put her own ambitions on the back burner to support her boyfriend, Kang Seung Woo (Yoon Sang Hyun), through school. He is now a successful accountant and she is unemployed, but as she quickly approaches 30, Na Ra knows that she can marry Seung Woo as the next step in her life.
But Seung Woo returns from a business trip and breaks up with Na Ra on their anniversary after having an affair and falling in love with another woman, Chae Mi Rae (Park Eun Hye). Na Ra goes to confront Mi Rae, who works for a cosmetics company, and sees a job posting. On a fluke, Na Ra decides to apply for the position, but she has to pretend to be her younger sister, who has a high school diploma, to get the job.
But what has Na Ra gotten into as she clashes with her immature coworker, Na In Jae (Kang Ji Hwan)? “Fireworks” is a 2006 South Korean drama series directed by Jung Se Ho.
