Shin Chung-han ran to the prison to help Kim Hyun-soo take care of everything in the detention center. Kim Hyun-soo’s family received a call from another barrister, Park Mi-kyung (played by Seo Jae-hee), stating that he would unconditionally help Kim Hyun-soo in the lawsuit, privately just to increase his popularity. This incident made Shin Zhonghan think that his case was robbed, and it also made him worry about Kim Hyun Soo's case.
An Tae-hee applied for a polygraph for the case of Kim Hyun-soo. Park Sang-beom thinks that it will take half a month for the identification to be carried out. He wanted to postpone the investigation time. Tae-hee An explained that if Kim Hyun-soo refuses the polygraph, it will be beneficial to the trial. As evidence, An Tae Hee asked Park Sang Bum to persuade Kim Hyun Soo to perform a polygraph. When Kim Hyun Soo came to the interrogation room, An Tae Hee first verbally intimidated him and stated that he would prosecute violence and homicide. At this stage, Kim Hyun Soo denies that he does not remember. For crimes, there will be life imprisonment for betrayal.
Prior to the polygraph test, Park Sang-Bum deliberately asked him to see Hong Ju’s body, causing Kim Hyun-soo’s mood to fluctuate, and not allowing him to take any medications related to asthma. Although the polygraph did not have any legal benefits, Kim Hyun-su agreed to claim his innocence. During the polygraph test, he asked too many questions about the content of the case, so Shen Zhonghan discovered that this was a scam and refused to continue the polygraph test on the spot.
On the day of Hong Juhua’s cremation, Shen Zhonghan also came to the ceremonial venue to observe all the people who came to participate in the sacrifice. He also found that Hong Juhua also saw the physical and mental department. When he came to the clinic, Shen Zhonghan asked the doctor about prescribing fentanyl to Hong Juhua. This is similar. Drug prescriptions are signed for up to three years.
