Agent X (2013)

Both go through misunderstanding and both still fall in love. Also both female lead has someone in her family dead.

Tang yang and Luo jing are both main actors.both is when they first meet and fall in love.And they both end up ****

If you ship Tang Yan and Luo Jin, you would like this series also!
Violence is the key in this drama...with romance and drama between the two, of course!

Rookie Agent Rouge has a very similar plot to agent x. There is many parts of the rookie agent rouge that reminds me of Agent x. Both female protagonist does what they think is right and fights for there country while both male protagonist helps the female protagonist grow with a bit of romance in both dramas.

Same couple!! Tiffany tang n luojin have so much chemistry together so they definitely have to end up together!!

Both dramas have strong female leads and revolve around undercover spies (trained to spy and kill) who are trying to help their country fight off foreign influences.
