I think I can say that I have very little tears left after watching this drama. I had to take a few short breaks throughout watching this, but overall I really enjoyed it. It was very emotionally draining. The cast choices couldn't have been any better, lots of my favorite actors/ actresses were in it. A long the way I found many new favorites too. IU was amazing in this, the force crying and acting from everyone was phenomenal. I found the story line very good but it is quite tragic. Be prepared to shed some tears and not be able to stop watching, its addicting. You just want to know what happens next. This was my first historical drama, I went though so many tissue boxes. I don't think I could watch it again though no matter how good it was because I would just be too sad. If you don't mind crying during your dramas then totally recommend, very romantic too.
