In "Signal" it was revealed that Lee Je Hoon and Jo Jin Woong were connected to each other by Lee Je Hoon's older brother.
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) and Jae Han (played by Jo Jin Woong) were connected by none other than Ha Young's older brother.
Hye Young said that thanks to Jae Han, Soo Hyun (played by Kim Hye Soo) solved her case and asked what kind of relationship he ahd with Chi Soo. Soo Hyun had seen that all the cases that Hye Young took on were related to Jae Han.
Hye Young pretended not to know and Soo Hyun said that Jae Han had met Chi Soo for the first time after the incident in In Joo. This was a serial rape case in 1999.
With that, Hye Young was shocked because In Joo was nothing other than his hometown. It turned out to be a case relevant to his brother.
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.
