Genuinely enjoyed the grittiness of this drama. I will say that there is a misconception (a few) about the disorder DID. Which is dissociative identity disorder which in the show is referred to as an “alter ego” do some research after you watch and it will make sense. I have watched this show a total of 2-3 times and each time I enjoy it.
Paired with my two favorite Korean actors it was really unexpected but I loved it when the show was released. Anything these two play in always turns out to be amazing.
