I am usually not one for thrillers but this drama...it touched my soul.

The acting by Lee Joongi and Moon Chae Won was beyond words. This drama is definitely one the best I have ever seen in all the years I've been watching dramas. The directing and production brought this already incredible script to another level of brilliance. I can't leave out the editing and the beautiful additions of the OST.

Each actor performed their role so brilliantly that you're glued to screen wanting to know what happens next.
Everything about this was just phenomenal. I am so happy that director Kim Cheol-Kyu won the award for Best Director at the 57th Baeksang Arts Awards. It is truly deserved.

P.S. I've known Lee Joongi's since 'Moon Lovers: Scarlet Heart Ryeo' and Moon Chaewon from 'The Innocent Man'. So I knew both of them were good. Moon Chaewon however completely blew me away with her performance. I am now officially her fan as well.
