In "Signal" Kim Hye Soo looked at Lee Je Hoon with a suspicious look as he was interested in Jo Jin Woong.
On the episode of tvN Friday/Saturday drama "Signal" (script Kim Eun Hee, director Kim Won Suk) broadcast on Feb. 19th, Park Hye Young (played by Lee Je Hoon) asked Cha Soo Hyun (played by Kim Hye Soo) about the relationship between Ahn Chi Soo (played by Jung Hye Kyung) and Lee Je Hoon (played by Jo Jin Hoong).
Hye Young asked Soo Hyun whether Chi Soo and Jae Han were close to each other. Then, Soo Hyun said, "It's weird. When you look at the cases that you're interested in, they're all the ones that's intertwined with Lee Jae Han" and started to show her sixth sense.
Soo Hyun said, "I don't know how close these two people are. Lee Jae Han first was sent to In Joo and met for the first time. Flee Jae Han was also involved with the 1999 case with serial rape of high school female students."
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.
