In the real world, people don't go missing without there being investigations into it. Take the MC's father, for instance. His workplace would be wondering what was up and would've reached out to his family. His family would've put in a police report. It would be one thing if he was targeted hookers on the street, but he is targeting established members of society. It *would* be noticed. The level of suspension of disbelief this manga requires is pretty egregious so far.
*targeting
If they had just called the fucking police and reported him...
