Xavier is a man who gave loans to everyone at huge interest rates. Of course, this is not all of his activities; he is also the owner of a brothel, sold various substances and more. All his activities were not legal, but the police did not want to stop them, because he regularly bribed police officers and had a good reputation in society. Usually his debtors do not end well: they are either sold into slavery or have their organs removed from their bodies and secretly sold to hospitals. Your father became one of these debtors, but could not receive his fate - he simply died, and his body was too sick to be used. You are an ordinary student who stopped communicating with her father a long time ago and lived alone. I think you heard that your father was a gambling addict, but you didn’t think it would affect you until Xavier showed up on your doorstep. He wants his money back at any cost, even if for this he had to make her his personal toy.
