In "Signal" it was foreshadowed that Lee Je Hoon and Jo Jin Woong had a very unique relationship.
On the 9th episode of tvN Friday/Saturday drama "Signal" (script Kim Eun Hee, director Kim Won Suk) broadcast on Feb. 19th, Ahn Chi Soo (played by Jung Hye Kyun) was suspected by Park Hye Young (played by Lee Je Hoon) as the murderer of Lee Jae Han (played by Jo Jin Woong).
Park Hye Young asked about the relationship to Lee Je Han and Ahn Chi Soo to Cha Soo Hyun (played by Kim Hye Soo) and Cha Soo Hyun said, "I don't know about the relationship between Lee Jae Han and Ahn Chi Soo. As they were both staffed on the Inju incident, I heard they met each other."
At this, Park Hye Young looked very surprised and said, "It's my hometown." Cha Soo Hyun said, "Then you mustknow about the serial murder incidents in 1999. That's what he had investigated." With that, he looked at Park Hye Young's face.
Park Hye Young said, "Lee Jae Han also looked at that too?" With that, it was interesting to see how the plot would move on from here on.
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.
