In "Signal" Lee Je Hoon started to suspect Jung Hye Kyun.
On the 9th episode of tvN Friday/Saturday drama "Signal" (script Kim Eun Hee, director Kim Won Suk) broadcast on Feb. 19th, Hye Young (played by Lee Je Hoon) started to get very suspicious of the activities of Chi Soo (played by Jung Hye Kyun).
Again, Jae Han (played by Jo Jin Woong)'s walkie talkie communication started. When Hye Young wanted to receive a walkie talkie communication, he found a walkie talkie in his drawer.
Hye Young said, "Why does the director have this?" With that, Chi Soo said that this is what Jae Han had carried like a part of him. "The people in the auditing room were looking in the mountain and found this. It was a piece of evidence and it was going to be thrown out. Why do ou have it?"
At this, Hye Young said, "Did you observe me? With that, he knew that he was investigating Lee Jae Han but Hye Young said, "Is there a secret I don't know?"
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.
