I'm writing this review after hearing all the mixed opinions on this drama and finishing the very last episode. So I watched this drama since it was airing and trust me this is beautiful. It got me hooked till the end. The plot is full of mystery and thrilling but still it has its own beauty<3. The cinematography and acting is top notch. Yes the pace is a bit slow but it's totally worth watching.The storyline is totally different and it met my all the expectations I had from this. Firstly I watched this for Jun Ji Hyun cuz she is one of the best actresses out here. Everyone has done quite justice to their characters. I enjoyed this non- romantic suspense filled healing plot a a lot. If you're looking for a good action thriller this is for you. I was too scared for the ending but it turned out to be equally beautiful. The ost will heal and sooth your soul. I totally love this one. Highly recommended<3
