That would not be a plot twist but the end of the story (the main character dying).
I understand that Finder romanticizes violence to a certain point, but let's not forget who Asami is and how he behaves with people; as with things that can be discarded at any moment due to their uselessness or control them, subjugate, the same happened with Akihito, but he does not treat others differently, with Feilong there was a different story, although there was an attempt to manipulate sex, but not so rude because of the business prospects of working with Feilong. But we must not forget about Asami's profession and by what methods he could get through to where he is, perhaps this is the cost of upbringing, love and respect is brought up from childhood, and if he was not in the family, then how would he know what it is? Now Finder is losing its popularity due to its bad attitude towards violence, but if you want to read about an office worker, his sweet intern and other, where the relationship is rosy, declarations of love, then you are reading the wrong manga. Unfortunately, violence is probably the main feature of the manga, nothing can be done about it.
Sounds painful for you. Many find solace in prayer.
If Asami's really dead,I would definitely give it 5 stars because It's really amazing and that'd be a good plot twist lol but I know the rapist probably won't die.the mangaka cannot kill him because of his fans.this is so fucking sad...
