Even if the Busan Police try to frame him as having a thorough dual personality, it lacks credibility...

There is actually a reason why it is useless to try and frame the Busan police officer as a psychopath.
It seems they are trying to do this because the Busan police keep causing trouble, making them look bad. Therefore, in order to make excuses, they have to frame him as having a dual personality that thoroughly hides his true self.
But even that is difficult. I know that my writing will cause a backlash.
The truth is, he has been writing since he was young and has won several awards. If you read his writing, you can tell his character and integrity. Being able to write well means a person has deep thoughts.
Furthermore, those writings were received from credible institutions. For example, even if they aren't at the level of the Chunye Literary Award, he writes decent essays. And those writings were evaluated by professors of Korean Language and Literature from four-year universities. If the President had actually read those writings, he would have certainly asked, "Who did this to you?" or "This person doesn't seem like this type; why did this happen?"
So, he is actually quite far from being a psychopath. The antisocial personality traits appeared because it became difficult for him to endure the police officer's unreasonable investigation. So, while he was resisting, people said, "He's a mental patient."
That is why my writing is causing a backlash.
Citizens say, "He must have a lot of grievances in life; he can't even control his own emotions."
But when they look at his award-winning works, they say, "It seems like they committed severe human rights violations against him."
And people say, "This is happening because you are articulate." A person with deep thoughts is also a person who speaks well.
