In "Signal" in 1999, Kim Hye Soo was still in love with Jo Jin Woong.
On the 11th episode of tvN Friday/Saturday drama "Signal" (script Kim Eun Hee, director Kim Won Suk) broadcast on Feb. 26th, the detective squad of 1999 was shown on screen.
Cha Soo Hyun (played by Kim Hye Soo) had had a crush on Lee Jae Han (played by Jo Jin Woong) for several years. Nonetheless, Jae Han didn't know this side of Soo Hyun. Other than him, the other detectives in the squad knew about Soo Hyun's feelings and the fact that she had a crush on him.
The detective said, "How do you not know this at all? What did Cha Soo Hyun get smitten by?" Seeing the very unneat side of Jae Han, they said, "It's a mystery. It's a mystery."
In addition, the detective squad leader said, "Tomorrow is Valentine's Day? You don't have a girl to give you chocolates?"
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.
