7th Grade Civil Servant

7th Grade Civil Servant is a 2013 South Korean television series starring Choi Kang-hee and Joo Won as rookie spies who trained together, and later become NIS agents who must hide their real identities from each other even as they fall in love. It aired on MBC from January 23 to March 28, 2013, on Wednesdays and Thursdays at 21:55 (KST) for 20 episodes.

The series is a remake of the 2009 film My Girlfriend Is An Agent. Early working titles were "Secret Agent War" and "The Secret Lovers".

Plot
Love and espionage collide in this drama of the National Intelligence Service's rookie agents. Han Gil-ro (Joo Won) realizes his dream of becoming an international man of mystery, after a childhood spent poring over James Bond films. Kim Seo-won (Choi Kang-hee) spices things up as a goofy, yet determined agent, but it's not all 007 glamor. Both Gil-ro and Seo-won must learn what it takes to uphold their sworn duty, even at the sacrifice of their happiness — and lives.
