This drama is so powerful. The cast is amazing, the chemistry is just perfect, and the story never gets boring. Lee Seung Gi, Bae Suzy, and Park Tae Seo are the most interesting cast combination I have ever seen in a k-drama. Needless to say that Lee Seung Gi probably is one of the top South Korean drama actors, if not the best one.

It is fair to say that the rewatch value of this drama is and will always be a well-deserved 10/10. I am still waiting for a second season. Gu Family Book is a drama worth your time!
