What an amazing drama. Not what I have seen for the past few years. I followed the 2 time lines smoothly, and able to feel pain of different generations. Lee Min Ho slayed his role as Koh Hansu, I loved and hated Koh Hansu at the same time. But I always love Lee Min Ho. Jinha and Kim Minha and young actors are so so good as well. A must watch drama for this year.
