On the 16th and last 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) fo the past barely saved his life in Sunil Mental Hospital
Kim Beom Joo (played by Jang Hyun Sung) tried to kill Lee Je Han. Ahn Chi Soo heard Kim Beom Joo say pick either his daughter or Lee Je Han. With these words, Lee Je Han was pointed a gun at.
However, at the minute that the run was about to be fired, Lee Je Han's colleagues appeared and Ahn Chi Soo and Kim Sung Beom were arrested.
Even in a situation where Lee Je Han had been bleeding a lot, he went over to Cha Soo Hyun (played by Kim Hye Soo) and said, "I kept my promise" and hugged, showing a dramatic side.
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.
