Following the events of their trip to Okinawa, Saitama University graduate students Shinya Yukimura and Ayame Himuro have failed to obtain the data necessary to scientifically prove their love for each other. Unable to replicate the exact conditions of the trip, the two stubborn scientists decide to seek help from elsewhere in the university—the Biological Sciences department.
