Perfect just for Kim Jung Hyun. Good series overall. The male lead carried all to make it interesting and enjoyable.
The chemistry of the lead couple is indeed not as strong as in Mr. Queen. Maybe it would be a hit if Shin Hye Sun is the female lead. But I definitely recommend it for people to watch in support of the male lead. He deserves all the honor and praise. May he have more projects to come with his lead in Mr. Queen. I think it was a wrong move to pair him with his female lead in Kokdu. His popularity is somewhat affected.
