Yukimura and Himuro wear lab coats, as befits science-types, as they get ready to begin their date experiment. Kanade is there to watch over their date and record observations, but she can't help bursting in to tell them to buy date clothes. Both of them are wearing monitors for heart rate, blood pressure, and temperature, and they're using an app to record things like "times my heart raced," "times I felt happy," "times I felt relaxed," and "times I felt uneasy." Suddenly, a man appears and starts hitting on Himuro...!?
When a roller coaster wants to travel 
around a loop with a radius "r,"

Se uma montanha-russa quer
percorrer um loop de raio "r",
Когда вагонетка проходит петлю 
с радиусом r,
