great drama

it was a great drama.... it's so underated !!!!
it's mystery and medical genre and thriller too ..
I watched it a long time ago but I just remembering it I think I'll rewatch
nam gong min did a great job,,,, but the psycho was my favorite character ? I liked the plot twists . it didn't have any boring episodes I finished it in 2 days .. you can watch it with your family too ..
I opened this drama to see nam gong min but ended up loving Choi Jin hyuk he was so cool
hope you enjoy it like I did
