Yukimura is working hard on his computer, as usual, when Himuro suddenly says, "I am in love with you. Her confession greatly shakes Yukimura. Unlike the last time, Himuro states her feelings matter-of-factly. Yukimura asks, "What theory did you use to determine that you love me?" Himuro replies by taking Yukimura out on a date and begins performing experiments they've done before such as measuring heart rates, using an emotion counter, collecting saliva, and the kiss experiment.
I did. But we measured heart 
rate before, didn't we?
أجل. لكننا قمنا بقياس معدل نبضات القلب سابقا، صحيح؟
Allerdings. Wir haben doch in der
Vergangenheit schon den Puls gemessen, oder?
Oui. Par contre,
c’est un essai qu’on a déjà fait.
Sì. Ma abbiamo già misurato
la frequenza cardiaca, no?
Sim, mas já medimos os
batimentos cardíacos antes, não?
Не забыл.
