I love this K Drama it was awesome. I learnt a lot of things, "they say an apple does not fall far from its tree", but sometimes its not always the case. We should learn not to judge people by other peoples character just because they are related.
But why is its the real Baek Hee Sung was still the same from 1997 he did not show some features that age changed and why did Do Hyun Soo had to have his identity when there was that age difference.
Also you did not let us know what happened to Jeong Mi Sook and her husband. And the fact that Do Min Seok did not commit suicide but was murdered by real Baek Hee Sung it was told.
Although it was a nice series
