In "Signal" Jo Jin Woong participated in the investigation of the high school students in In Joo.
On the 11th episode of tvN Friday/Saturday drama "Signal" (script Kim Eun Hee, director Kim Won Suk) broadcast on Feb. 26th, Lee Je Han (played by Jo Jin Woong) of the past asked, "Please tell me about the truth of the In Joo high school incident."
Nonetheless, Lee Je Han said that he doesn't cover In Joo and afterwards, the walkie talkie was disconnected. A while later, Lee Je Hoon said, "The victim is a high school student but there are more than ten people who are the perpetrators." With that, he was exposed to high schooler incident.
Kim Beom Joo (played by Jang Hyun Sung) said, "The special investigations team is going to investigate this" and with that, lee Je Han said that he would participate regardless of the jurisdiction after thinking back to Park Hye Young's words. Afterwards, Lee Je Han arrived in In Joo and met up with Ahn Chi Soo (played by Jung Hye Kyun).
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.
