In "Signal" Jo Jin Woong started to bicker with Kim Hye Soo.
On the 7th episode of tvN Friday/Saturday drama "Signal" (script Kim Eun Hee, director Kim Won Suk) broadcast on Feb. 6th, Lee Jae Han (played by Jo Jin Woong) of the past was really tough on Cha Soo Hyun (played by Kim Hye Soo) who was the first female cop of the division that he was in.
The police officers there even taught her how to drive, but Cha Soo Hyun made a lot of mistakes. Lee Jae Han felt frustrated saying, "That person has no answer. Kick her out" and was upset.
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.
