First of all, I was interested in this drama because of it's cast -- Kim Jisoo. It was Jisoo kdrama debut as a lead actress and I'm so happy that it's this much successful since her acting was worth it even thought her character was intense. On the other hand, there's HaeIn 's character, well, it's my first kdrama with him acting as a main lead and I liked his acting he played his role well.
As of the story, most of the charactres in this drama have secret and hidden identities and a back story which made it all interesting everytime there is a character with a secret identity I was so surprised when Man dong turned out to be a North Korean spy. Kang chung ya - I was mad at her because the way she treated young ro but I love In-na don't get me wrong here. Comrade Joo is a cold character and I didn't like the character at times but he died at the end in such a way that made me start to feel sorry for him rather than hate him it's sad. And all the character and other characters makes the story rich and intriguing. The and had me craving for another episode everytime. The ending is sad almost for every character young ro be living in tears her life after that huh it's sad :(
Jisoo's and haein's behind the scenes chemistry is my favorite thier visuals is outta this world!
It's worth watching!
