Who is the last murderer of slang lawyer rat identity?

As of August 22, 2022, the slang lawyer identity drama "Rat" has not been broadcast, so it is very likely that "Rat" is a group from the plot analysis.

First of all, Mayor Cui, the main promoter who entrusted the man to enter the case, was drugged by a waitress on his way to the mayor before going to prison, which led to the follow-up (the waitress must be a member of Shuo, but her status may not be high). ?

Followed by the head of the fortune teller in prison, the fourth episode is particularly obvious. The man joked that his attacker would die, and two of them committed suicide for no reason. Moreover, the director and the warden had a communication without subtitles, which was particularly suspicious. ?

That's not all. At present, the plot has not been updated. These two are probably members of Storytelling, especially the housekeepers. Almost certainly, there are two theories about the stolen goods in men's offices. ?

The first is that the man himself has a dual personality; Second, people around the man, such as lawyer friends and father-in-law. Otherwise, the stolen goods could not accurately appear on the upper ceiling of the men's office, which is a bit too coincidental.
