I love how this drama dives deep into its characters psychology. It's also extremely realistic and makes you wonder how you would have reacted if you were in their shoes. This is the first drama where I am totally invested in understanding the characters. I wanted to know what happened at the end of the show so I was planning on waiting for it to finish first but I don't care how it ends. I more more interested in what choices will be made at the end of it all.
Now may I just say also that I have never ever seen such chemistry like the two main leads have. It is incredible...really really incredible!
