I was confused at first too, but that you for explaining.
The whole point of the story was to make it fictional and many of the laws you've stated, can't exactly applied to the story as it is again fiction. You can choose to believe what you believe, but by stated by author, the story was to leave a bitter ending and it was not a happy one. He sadly did get kidnapped again, that's end game. Yes he did suffer from ptsd, yes he could have been hallucinating, but this story was to—in the end, be left on a very bitter note(●￣(ｴ)￣●)
I'm 98% sure he don't get kidnapped at the end. Here's why :
The case was highly publicized therefore it's impossible, even if you have 7 really good lawyers, to be set free in such a short amount if time because the public opinion matters in this type of cases and we know for a fact that it's not a good one.
According to the law in South Korea for this kind of crimes, the accused must remain in jail or can pay to get out but they must remain at home with an electronic bracelet and frequent visits by the police until the end of the trial.
There is not a single chance of him being employed during this period of time. You may think he changed his identity since he's rich but his face is everywhere in the media and he can't change that.
We hear at the end that he succeeded in imprisoning him again, but by that, the author wasn't talking about a physical imprisonment, but about a mental one. More commonly known as PTSD.
