Who is the murderer? Who is the murderer?

The ending of "Who is the Murderer" is reversed: Shen Haiyang has been dead for many years, and the murderer is Hu Daodao's father Hu Shanquan

The murderer sent an anonymous text message to Shen Yu: "You are wearing a white coat The way you look reminds me of when you were a kid, playing games and pretending to be a doctor." It can be seen from the content of the text messages that the murderer has a complete grasp of Shen Yu's growth over the past 17 years and has been monitoring Shen Yu without knowing it. It is very likely that he is the person around Shen Yu and the person who has the closest contact with Shen Yu. , is the hacker Hu Daodao.

Hu Daodao is good at hacking technology, and it is easy for him to send anonymous letters. When Shen Yu went to see Xia Mu's psychiatrist, Hu Daodao also said that the invitation card he forged was enough to be fake. All consistent with the information about the murderer disguised as Shen Haiyang. However, judging from the age of the murderer, it cannot be Hu Daodao. Could it be someone related to Hu Daodao, such as Hu Haiquan? Could he be Hu Daodao's father?

Hu Daodao and Shen Yu have a close relationship on the surface, but in reality it is very subtle. Hu Daodao once said that he and Shen Yu are "grasshoppers on the same rope." The relationship between Hu Daodao and Shen Yu was also hinted at in the opening animation. The little monkey couldn't find its father, and a frog appeared. It said it would help the little monkey find its father, but in the end it betrayed the monkey. The monkey here is Shen Yu and the frog is Hu Daodao. The ending of the animation also hints at the real ending. Hu Daodao will eventually betray Shen Yu.
