This special is all about beautiful sceneries and nice acting, of course. Before I had seen the main actor only in the villainous roles so it was quite refreshing and the charecters complicated feelings anfd yearnings were shown really well.
The story flows slowly meandering and unwinding like long walks that characters take. The moral lines are quite blurred but emotions are felt quite strong and thus enjoyable for a viewer.
Overall a nice addition to KBS special series in a high-quality 2017 season.
