'Connection' Episode 4: What Led Jang Jae Kyung to Suspect Detective Kim Chang Soo?

At the start of Jang Jae Kyung and Oh Yoon Jing's team up, she tried to save him from experiencing a relapse after taking the drug called lemon mulberry.

Although she was hesitant to take him to the police station, Jae Kyung insisted because he wanted to look into something.

As he slightly recovered from the relapse, he checked the CCTV to find out who possibly took the lemon mulberry.

However, what he saw was a tampered CCTV showing detective Kim Chang Soo at the police station.

Here, he suspects that his junior might know about his condition or that he is an accomplice.

Meanwhile, Park Jun Seo's wife, Choi Ji Yeon, confronted the insurance company CEO, Heo Joo Song, where her late husband got two of his insurances.
