Each episode has twists & turns. Each episode you'll think that he is the main villain. Many are disappointed to know the main villain in the end. But that's the thing I liked about it. Till the end, the audience were guessing who was the main culprit. In maximum dramas you can guess who the main villain is even before the revelation. But here you'll keep on guessing. In every episode I keep on guessing the culprit, which made me want to watch more. It kept me engaged. Thriller, Mystery & Supernatural all of it are executed well.

First drama where ML reveals that he has supernatural powers.

I like the fact that in the drama they keep on mentioning that Dong Baek memory scanning isn't enough as evidence. Because in reality it is impossible & unrealistic.

Dong Baek is reckless but smart. There is a reason why he behaves that way. Han Sun Mi is an allrounder. She is best at her work.

I love Dong Baek's relationship with Oh Se Hoon & Goo Kyung Tan.
