This is one of my favorite KDramas. I went into this thinking it was going to be okay. I even thought I might drop it because the story seemed boring. But once I started it, I couldn't stop. It's SO amazing. I loved the actors and the plot twists were amazing.

One of the few things I didn't like was that a couple of the deaths seemed downright "useless" or rather unnecessary to the plot. Another thing I didn't like was that the killer plot twist seemed a bit forced. Just to create another plot twist. But aside from that, it's just an outstanding drama that I recommend everyone to watch at least once
