I started watching this drama out of curiosity for Kim Jaejoong's acting, and he didn't disappoint. I thought he was surprisingly good in acting as a character who is somewhat stiff, lives a double life and is very much in love.

There isn't a lot going on in this drama in terms of story. Everything surrounds an item that two sides (North and South Korea) are after, but the movements in order to get it don't really start until halfway through the drama, which makes the first several episodes slightly boring. It becomes fairly action packed from Episode 8 onward.

I think this drama is worth a try if you like espionage, action and a little romantic angst. If you're a TVXQ/JYJ fan, you'll also probably enjoy watching Jaejoong, and it isn't difficult to sit through his acting. He actually is very good.
