At first, this drama was very unkind. I am ready to guarantee that this drama is not at all similar to the negative comments. Some of them have not watched the whole series and judged it too soon, that's why their opinions are not correct.
Anyway
I think Dr. Hwang already knew about Haru's brain and even predicted his reaction, probably the secret he wants to tell is that Haru is the reason of that death to make Haru think that he is really psychic and destroy him, but in any case, I can say that this series has a 100% happy ending! But terrible things will happen, however Haru can overcome them.
This is one of the best and most complete drama that I have watched in this genre, everything and everyone are in the right place and all the stories have tension. Also JYH looks damn attractive hahaha
