I watched all episodes , and I enjoyed this drama. In particular , last 6 episodes were fully satisfied .
Male lead acting is wonderful. This drama role is soft and IT geek . looks about 25 years old , another drama "Stealth Walker" role is smart tough guy, looks about 35 years old. The other drama"Sleepless Princess"role is fierce General(but inside gentle and lovely).
He can act various roles , so I wasn't able to discriminate a same actor.
He is able to act a wide range performances. Other idol actors usually play one pattern idol role , but He is different.
Also female lead acting is great. She is a beautiful lady , in particular her crying face is so beautiful .
Though I watched her first time , now I am a big fan of her.
