I'm a doctoral student at a top university in City A. On a dark and stormy night, I was kidnapped and trafficked. Then, on another night of thunder and rain, I escaped. I must have passed out from running too far and going hungry for too long. When I woke up, I had been reborn in the body of a high school student, and I even had a System. This System is really cool: it gives me one yuan per step, and I can earn points by doing good deeds, too... But that's not the point. The point is that I have to use these things to find out who trafficked me and get my revenge...
