Despite being an immoral host, Sofony had so many things that she didn't know about the world. Example of that was her unawareness of a certain someone flying to where she was now. Another example was whether the father who abandoned her was still alive or not.
No one was truly omniscient in this world. Or at least nobody was born omniscient and all-knowing. The system could definitely help a system user become one. But it would take a lot of patience, luck, and time. For now, there were so many she could enumerate, but it would take so much time to do that.
This was why she would stop at the most recent unknown plaguing her mind. It was why that man in a black waistcoat and white inner shirt acted so respectfully towards her leading her to somewhere another person would be waiting for her.
