In "Signal" Lee Jae Hoon's past history was revealed.
On the 4th episode of tvN Friday/Saturday drama "Signal" (script Kim Eun Hee, director Kim Won Suk) broadcast on Jan. 30th, Park Hae Young (played by Lee Je Hoon) reflected on the past.
Before this, Cha Soo Hyun (played by Kim Hye Soo) said to Park Hye Young, "This is the first time you saw a person die, right? From now on, you're going to have to see a lot of this so find a way to get through this." Park Hye Young said, 'This isn't the first time" he said.
Park Hye Young had watched his brother in the past cut his own wrists and commit suicide. The brother had been framed for something as it seemed like he was accused of something that he didn't do. Park Hae Young looked at the picture with his brother and thought back to the past.
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.
