In "Signal" Kim Hye Soo decided to attack her trauma head on.
On the 9th episode of tvN Friday/Saturday drama "Signal" (script Kim Eun Hee, director Kim Won Suk) broadcast on Feb. 19th, Cha Soo Hyun (played by Kim Hye Soo) said that she was the only survivor of the Hong Won Dong serial murder.
On this day, the midterm report happened and Park Hae Young (played by Lee Jae Hoon) said to Cha Soo Hyun, "Are you really going to get a hypnotic diagnosis? Even though you're a detective, it'll be a lot to think of the memories of the past."
At this, Cha Soo Hyun said, "It's because of me. I didn't catch the culprit then which is why there were more culprits." Park Hye Young said, "You didn't even see his face." Cha Soo Hyun said, "I don't know his face but I think I can find the house. It's left somewhere in my memory.
Meanwhile, "Signal" is about two detectives - one from the past and one from the present who communicate through walkie talkies to resolve long-time unresolved cases.
