Baishan was killed by Lee Byunghun.
Zheng Junhao was killed by the police to save Jin Taixi.
Jin Taixi died to save Big Boss, and Lee Byunghun died to save Kim So-yeon.
If you are a screenwriter,
The worst reasons in the film are Baishan and Cui Shengxian. This has something to do with Lee Byunghun's death. Lee Byunghun killed these two men.
Zheng Junhao did all these bad things for Jin Taixi, because if he didn't do these things, Jin Taixi would do them as a classic of her death.
Jin Taixi has seen Iris's flowers since he was a child, which is described in the sixth episode. In fact, this flower was planted by her mother and loved by her father.
The name of the organization is iris.
Iris means the end of Jin Taixi and Lee Byunghun's plays.
The reason why Kim So-yeon didn't die is that her whole family died. After what I've done for Lee Byunghun, it's meaningless if all the main characters are dead. Only one protagonist of the Hong Kong drama Race against Time survived, and it is impossible to die like a Japanese girl's whole family.
If the big boss runs away, it will pave the way for the sequel, because the ratings are so good that the script can be changed.
By the way, I forgot to mention the president's secretary. It was the secretary who brought them to Cheongwadae, and Kim So-yeon found out and killed them.
The "big boss" is related to the current president, and only one can be the former president. Otherwise, how could Baishan enter nss?
