You can always blindly trust Kim Taeri.

The drama was well-written, with every plot-twists in mind that would come out as surprising but explained well. The horror was spine-chillingly beautiful, the cinematography, the timeline from past to present was done well, and acting of each characters, main and support were superb.

The main story plotline was perfect but the side story of all those ghosts were heartbreaking. Just tells us, not every ghost is a vengeful ones. They were humans once just like us who just wants to protect their loved ones as their final wish. You will feel scared, anger, fear, sad all the emotions in one go as the story progresses, especially knowing a child was sacrificed by those rich adults who wanted nothing but had greed for more money. The child actress as we've seen from her other projects is such a talented one, she will become one of the best actress of her generation someday.

The past story of the ghost and how she was used by the rich depicts the true story of how rich would do anything and abuses the poor people in real life was mind-numbingly heart-wrenching and yet I felt even hatred towards the ghost for betraying her own family especially her own sister.

Everything about the plot was done fantastically and even if there was something missing, the acting of these actors covered it all.

Kim Taeri should be getting daesang for this acting role. Ku Sangyoung/the devil, her portrayal of a vengeful spirit with so much hatred towards people was perfectly brought to the screen from the pages. From being just a child who wanted nothing but affection from others, the feeling of loneliness, then to such spiteful spirit she did so well. Not only her body language, even her eyes will be acting at the same time.

You should definitely watch the show if you love Kim Taeri and love horror genre. It's one of the memorable story that will make you want to re-watch as soon as you're done watching it the first time.
