In "Signal" Jo Jin Woong wanted to look for a culprit and started to go harshly on Kim Hye Soo.
On the 10th episode of tvN Friday/Saturday drama "Signal" (script Kim Eun Hee, director Kim Won Suk) broadcast on Feb. 20th, the long term unresolved murder team went ahead to try to find the culprit of the Hong Won Dong serial murder team.
In the past, Cha Soo Hyun (played by Kim Hye Soo) was a victim of this incident as well. She had been kidnapped by the murderer. At the time, Lee Jae Han (played by Jo Jin Woong) wanted to find evidence for the one who was guilty and started to investigate into Cha Soo Hyun's story.
Cha Soo Hyun was scared and said, "I think his voice was a male and his hand was cold and slender. He said to wait a little and then left" as he started to explain about the murderer.
At this, Cha Soo Hyun said, "The door opened and there was cold air. If I didn't leave then, I thought I was going to die. That's why I started to look for the door. But I couldn't" as he thought back to the memories.
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.
