In "Signal" Lee Je Hoon wanted to quit using walkie talkies with Jo Jin Woong.
On the 7th episode of tvN Friday/Saturday drama "Signal" (script Kim Eun Hee, director Kim Won Suk) broadcast on Feb. 6th, Park Hye Young (played by Lee Je Hoon) connected with Lee Jae Han (played by Jo Jin Woong) of the past. As the walkie talkies were connected again, he said, "At that moment, the detective told me. This walkie talkie should not have started."
At this, he said, "I don't know why this walkie talkie started but I think it's best to not do this anymore. I think it just causes more confusion. Please be careful" he said as he hung up the walkie talkie.
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.
