In "Signal" Lee Je Hoon learned that Jung Hye Kyun had requested the information on "Park Sun Woo's suicide incident."
On the 14th episode of tvN Friday/Saturday drama "Signal" (script Kim Eun Hee, director Kim Won Suk) broadcast on Mar. 5th, it was revealed that before Jung Hye Kyun had died, he was doing background investigation not on the In Joo incident but the Park Sun Woo suicide incident.
On this day, Lee Je Hoon was surprised that what Jung Hye Kyun was investigating was not the In Joo incident.
Lee Je Hoon went to the house of the detective that had taken on the case of the "Park Sun Woo corpse incident." Lee Je Hoon asked him whether there was anything that was suspicious about that incident. This was a very dynamic and tense situation and he realized that Lee Je Hoon's brother's death could possibly not be a suicide.
From the current standpoint, Jung Hye Kyun said to Lee Je Hoon, "If you can know things about your father's death and still be able to handle it, come down to In Joo."
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.
