I feel so emotional whenever I watch the drama, even the clips on YouTube/Facebook. Have watched this drama, don't know how many times, not sure.
The two main characters are complicated and simple at the same time. Love the chemistry between the two.
I just love the lead actress Kim Go Eun.
Have watched most of her work. Lead actor Park Hae-jin, played the role so nicely, coldness in his eyes in some of the scenes, is breathtaking.

I would recommend to watch this drama for the two lead characters.
