Murder Standard Score 70

Synopsis:
Miyahara Keisuke overslept on the day of his Tokyo University entrance exam. To delay the exam he sent a warning email to the University, indicating that a bomb had been placed in the university. Keisuke then rushed to the University, and was pleased to find the place in chaos. Due to the bomb threat hoax, the exams were delayed for an hour, which allowed Keisuke to sit for the exam after all.

3 months later, the results are out. Keisuke is overjoyed to see that he had passed. His girlfriend, Rikako is very happy for him too. Rikako is already a university student, but due to Keisuke's past failures at the entrance exams, it has been a bittersweet relationship to-date. She is happy that Keisuke will now be a fellow undergraduate, and that their status in life are now on par with each other. Keisuke's dad back home is also ecstatic about his son's success. When Keisuke was but a child, his dad's factory had ran into financial difficulties, which resulted in his mother running off with another man. To Keisuke, the acceptance into Tokyo University is a way of showing his mother what she had missed when she had abandoned Keisuke to be raised by his father alone.

On the day of the entrance ceremony, Tanaka Hiroshi is standing in front of Keisuke. He turns around and says to Keisuke, "I know what you did for the entrance exams, how it was suspiciously delayed. Shall I go to the police with the information?". Hiroshi starts following Keisuke around, demanding money in return for his silence over the matter. Keisuke, who had thought life would be all rosy at Tokyo University, is now overcome with fear, and has to even resort to questionable methods in getting the money to pay Hiroshi. As Hiroshi's demands become bigger and bigger, Keisuke becomes desperate and vows to end it once and for all...
