I'd assume that, as a high schooler, her yearly income wouldn't be nearly enough to support her research on top of supporting herself, and that the financial backing the University and/or the high school gives her for her research is probably not enough to cover all the expenditures required for doing her research. Thus, to ensure she has enough money that she can afford and continue doing her research - and potentially some side-projects, - she figured that there are always some desperate men out there willing to throw tons of cash her way just to get to have a one-night-stand with her, the perfect quick cash-grab opportunity for someone in her situation.Really? Why would the genius high schooler feel the need to prostitute herself? The fuck?
This story really does not make any sense.
