I think that this drama was very intense, and for me, there was a lot of tension because of the many things at stake, which is why I also feel that the payoff was very good. I found the plot very creative and I think that the ending was very good and very emotional. (I cried so hard that I got a headache). I really need to praise Kim Ui- Seong, as I think that he really did an amazing job at acting, as his character was complex and I feel that it would've been hard to portray. In conclusion, I think that this drama is very good and deserves a watch.
