There is No Smoke Without Dog - S1.E9

For some time, Natsuno has suspected she is being watched. One day while she is out, someone breaks into Natsuno's perfectly secure room and removes a single book. It happens to be the book she just purchased at Sakura's recommendation, the winner of the full-length novel special award, Heiando's newest author Hotaru Fujimaki's "Keisei Love Story."
