Is Guo Zhui or Lark the ultimate planner of The Lost Bullet?

I think it's the planner. Both make sense.

Perhaps the most accurate statement is this: Little Lark and Guo Zhui both want to pursue their own justice. Then the lark used Guo Zhui, and of course, it may also be a cooperation to create a serial murder case. The purpose is naturally to let Guo Zhui be the director to safeguard justice.

The lark's doubt is 1. Although Guo Zhui finally said that the lark was only responsible for collecting money, Guo Zhui recalled what he said to the lark before committing suicide: I will protect you anyway.

2. The case of Mr. and Mrs. Jiang has always implied a truth: the most perfect murder is not how the murderer carefully designs to erase the evidence, but how to have a good scapegoat after killing.

It is ok to take Guo Zhui as the last scapegoat, and it is a willing scapegoat.

Of course, it doesn't rule out that Xiaoyuer also fell in love with Guo Zhui. It's not that she deliberately took Guo Zhui as a scapegoat.

Of course, there is no doubt that the bullet that can disappear is Guo Zhui, and the planner must have her. After all, it was carefully planned by him.

So the mastermind cannot leave Guo Zhui.
