Who is the murderer and who is the bad guy?

Who is the murderer? Hu Shanquan is a bad person. He is the murderer of Haizhou case. 17 years ago, he killed five people in a row and has been at large. Hu Shanquan is mentally ill. He thought in his heart that the victim had betrayed her, but it was all his own imagination. Hu Shanquan also ruined Shen Yu's life. Shen Yu always thought that his father was still alive.

Shen Yu did many illegal things to help his father Shen Haiyang get rid of suspicion. In the last few episodes, Shen Yu found a scapegoat, He Weiguang. During the period of seeing a doctor, He Weiguang thought he was the murderer. Why did Weiguang change the case privately? All this is in Hu Shanquan's eyes. Hu Shanquan wants to be with Shen Yu, not Shen Haiyang.

At the expense of killing Shen Haiyang, Shen Yu has been living under the surveillance of Hu Shanquan for so many years. Hu Shanquan changed all the photos of Shen Yu and Shen Haiyang into his own photos and forged his identity. After meeting Shen Yu, Hu Shanquan always claimed to be his father, which was really horrible.
