I binge watched it so I don't have many complains because I can handle some plot holes.
This drama gave me so much anxiety. It really kept me on my toes! Suzy's acting really touched at times I cried with her. I don't know why people say her acting is not good they should watch this drama. I binged watch this in one sitting. I really couldn't stop myself from watching the next episode.
Also the background music at times was good, was making me anxious lol.

There were some things that I didn't understand. But I heard there will be an extended version in August so let's wait.
