I don‘t think any drama has ever f*cked with my feelings this much before, not even Rise of Phoenixes (which had my heart aching for quite some time).
I will say that I do not read any summaries or anything before watching Dramas, so I did not at all know what I was getting myself into.

Both female and male actor portrayed their roles beautifully.
What fascinated me the most about this Drama is that there is A LOT of Drama and unhappiness, I felt a very uncomfortable heaviness in my chest all the way from ~ EP 10 till the end. This one will get your hopes up and crush them. And even though I usually hate a lot of Drama, here it all made sense in a way, and did not get boring nor feel stretched out for a second.
It’s been a while since I‘ve finished a costume Drama this fast! If you are looking for something to really make you feel, give this one a try!
