I watched this drama when it was aired back in 2014. One of the best dramas. It has everything: Good cast (The actress and actor Lee Bo-Young and Cho Seung-Woo did such an amazing job), the scenography and the cinematography is just splendid and with such detail. Overall one of my favorites.
The story was on point even though I did not like the twist at the end. It was well scripted and will repeat it again.
