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...!?

ما دام سينطلق من نقطة ارتفاع 5 على 2ر 
.سيكون كلّ شيءٍ على ما يرام
finché partono da un punto alto 5/2r non ci sono problemi.
ela precisa partir de uma altura
de, no mínimo, 5/2*r.
она не упадёт, если зашла 
на петлю с высоты в 5/2 радиуса.
